F was surprised to see in a book on polluter science recently published tt chaple' evaded "Tho Alchemists Were Right" anti to lied that the au thor believed that, as regards ih trio usmntatte1 of I 11 chemical ole snouts, "the 0101101010 ts were flunks mentally right". It is true that mho )(10110101010 were aware that gold and other precious metals were different 100m baser ones, and that they col 0010011 the idea that the latter might Abe changed into the former by heat, the use of chemicals, or other artifice; it is true also that transmutation of elements is a process occurring la na- lure and one that has been rattled out in the laboratory. It may be 0r• geed, therefore, that in ono sense the alchemists were right in that they at- tempted to do In their (lay, with the little knowledge and technical me thuds available, what the vast re- .sol1le(s of the twentieth century have shown to bo possible. A closer ex- aminatiou of the facts, however, will shoo• that where the alchemists fail ed sae fail, and that It is knowledge of the fundamental part of the atom, the nucleus, 0111011 has lid to our success. The alchemists wore only right in that they could not de what 0c'cumlot do; 501110lly they were fundamentally wrong, Claims that transmutation is occur- ring us may occur come front three sources, i11 radio -activity it is claim ed that the very heaviest elements are undergoing a spontaneous trans- formation which results veitiably 10 time [production of one element from 0110!llsr. Secondly, 1t 10 claimed that when certain of the lighter elements more particularly nitrogen fluorine, so0ulrn, aluminium and phasp::ous, are bombarded with the charged atoms of helium, ejected by radium and other Indio -active elements, hy tiro;+n and probably other elements are formed. Lastly there are claims of a miscellaueoes character; the production of gold from mercury, of tnereu03' from lead, and of thallium from lead by electrical means, the breakdown of tnngstet into 11elhtin by Passage of a large electric current, and, most astonishing of all, the pro- duction of 0011(101 front ]hydrogen 10 presence of the rare metal palladium. 11 is accepted at the iso prr,semt time that in radio -active clmnge tram. muteflon is occurring In nature. The characteristic property of an element Is its unique atomic number, the post• tire charges borne by the toy 1111010115 situated at the centre of every afoul. Thee nurleme of an atom of a radio- active element Is able to expel) part of itself spontaneously in two ways; either as an atone of helium bearing. two positive charges of electricity, or as an electron, one negative charge. In either case, ,01nc0 the charge on the (melees is altered, the nucleus of one element has become that of an- other, In this way every radio-ac•I live element known is becoming trans- muted more or loss quickly into an-. other 0101110111. The radio -active e)e-' melds are, however, confined to the very heaviest of elements; bismuth,: lead and mercury, heavy though they are. are just too light to lie within the raig0 of elements 01(111) are ratllo•' active. Other characteristics of 1110 radioactive 01011100LS are the 0)00(1 taneily with which either the charg-' et) atom of helium or tie electron are ejected from the nucleus and the very large amount of energy whicit accom- panies these °)cottons. Alterations of temperature and pressure and the application of large quantities of elec- trical energy have altered not a 'whit the rate at which a raddo-activo transmutation occurs. It is a pro• cess which man can observe; he does not know how to alter it; he has not au00001ed in imitating it. Before man existed radioactive changes wore proceeding at exactly the sante rate as they aro now observed to proceed. 1 T`e second claim, the production of 1 hydrogen and possibly other elements from the bombardment of light ele- needs by charged helium atoms, le 1 also accepted as genuine transmute - tion. The charged helium atom spantoneously e)0cled by the radio- active °lenient radium 0 is shot out 1 with a velocity of about 12,000 miles e per second.. It Is a very, very tiny s inejectile, but, plass for mass, has t .boat 400,000,000 times the energy of e a rifle bullet, When it strikes a 0 carom of zinc sulphide it emits a n Pas'' of light which may be observed g through a low-power microscope by n eyes well rested in the dark, The flash has been proved to be due to the 1 collision et a single charged helium P atomwith the molecues of the zinc p sulphide scree 1. It is found, how - over, that if the screen be moved 10 oxygen at atuosphe'0 prossmdo m000 than 7 centrinlelres from the radium, no light due to theeo charged atoms e can be observed; that is because the 7 centimetres of gas offers so 11111011 resistance to the passage of these charged atoms that they lack the energy necessary to cause a flash of ligirt. If, next, these atoms have to force theft passage through a thin sheet of paper or mica, or metal they are found to he stopped nine' 000n - or; they go, however, a distance which is roughly inversely proportional to the density of the thin sheet inter- posed. Sir Ereest Rutherford and Ibis pupils have shown that in cer- tait cases anomalous results are ob- tained. If a sheet of aluminium equivalent in stopping power to 7 - centimetres of oxygen be interposed betwce.n the zinc sulphide scrum and the radium there ought to bo no flashes; actually flashes aro obtained on the screen even when it Inas bees moved so far away as 90 centimetres. These flashes have been shown to he duo to tiro impact of charged hydro- gen atoms which, it was Inferred, had broien off from the nuclei If alumin- 11un 0s a result of headlong collisions between the laitor nod the charged nine of helium The nlunnbe of alunf- Miens nuclei struck 111 this way is re- latively extremely small. Sir E. Rutherford has calculated that only about two charged helium atones col. lido In such a way with the alumin- ium nucle1 that a piece of hydrogee is broken of, although each passes through about 100,000 atoms of alum- inilun Imbue it is stopped; that Is to say, there are only two really success ful lits of this kind in 100,000,000,000 shots, Both at Cambridge and in Vienna this subject has been greatly studied and about a dozen elements of which nitrogen, fluorine, sodium, al- uminium and phosphorus are chief, have been attacked in this remark- able way; 10 every case hydrogen re- sults, The question whether the hydrogen cones from the target (the nitrogen, aluminium, etc.) or from the projectile (talo charged atone 'of helium) has been answered es "neith- er" by experiments with nitrogen in Sir E. Rutherfortl's laboratory. The hydrogel Is ejected after Projectile anti target 110vo coalesced, leaving be- hind an atom that is very probably 011 atom of oxygen with the 0lnlormal atomic mass of seventeen, instead of the usual sixteen. This Is the first i case known in which a heavier ele- meat has sen made from a Helder In the lao'atory, oxygen being heavier' than nitrogen, This extremely inter eating branch of knowledge 1s at pres- ent 111 Its infancy. It rentable to discuss briefly the; last class of supposed transmutation, the production of gold from mercury, 1101 flint from tungsten, 11011001 from hydrogen, and so forth. These claims have been persistent of late, and have conte from all over the world, but no case is accepted by the scientific world as genuine, In such as have been critically examined the supposed transmutation has been shown to be simply an unexpected contamination of the originally pure element by the element into which trans.the former was supposed to be trans. muted, Thus, the production of a very small but definite quantity of gold from mercury by electrical means has been traced to contamination of the mercury by gold 00010 objects in the laboratory, such as the spectacles of the experimenter; the helium, pro: (laced from the hydrogen in contact with the metal palladium, has been Graced to the air supposedly excluded from the apparatus in which the ex- perhnent was taking place; and so forth. When really rigid precautions are taken to exclude the possibility of contamination of the element, which' s supposed to result front the trans; nutation, none of it lo found. Not all the eases of this hind have been disposed of in this way, but there is no likelihood that those outstanding differ in Rind from those investigated. These experimental failures, although disappointing to those who would Ike to take gold from lead or mer- ury, or to tap the supposed enormous torn of energy 01111in the atom, are o bo expected from present 011501 - age of the structure of the atom, The sseltdal part of the structure, the ucleus, Is known to be so tiny and so marded from attack, that such ther- 101 and electrical forces at present available for direction against it aro oughably inadequate. The only 1-0otieal suggestion so far is the enh- loymont of the swift charged atoms Il Canada's Most Popular Winter Sport ANSWER THE CALL OF WINTER TO OUT•OF-DOORS The photograph here shotes three young 'Toronto ladies, all enthusiasts of the glorious 011000 of skiing, ready for a real time in Ifigh Park, Toronto, Less of boli t)s elements, many oP t -ahe World's Wheat Less radioetSve eleeuts, and, as stated World �j% above, Herta are epowerless excret Than Last Year against contain of the 11„ hto• 01010011t0.

Until re cantly he has had no practicable means of taking bearings on invisible objects, The radiocoupass on shipboard and the radfobeacon at lighthouses and on lightships provide the navigator with the most important additional help since the mariner's compass became known the first successful signals of this hind were established In the ap- Preaches to Now York, and the sys- tem las since been extended by the Lighthouse Sovic of the Department of Commerce, so that there are radio• beacons at the more important light- ships and lighthouses along the coasts of continental United States and Canada, the Great hakes, the St, Lawrence River, with a few in Alaska and 1)000)1. Important tsignals have recently been placed at mho 1100 approaches to the Panama 1 Canal. Itadiobeacous are also being t installed by the other leading maxi - time countries, Radio Compasses on Ships A considerable proportion of the larger ships in tlho world are now equipped t*ltll radioeonpassee for tak- ing radio bearings. The navigates may tante these bearings himself, and the general problems in their use are essentially the same in principle as in the use of visual bearings; the practical differences between radio and eight bearings are not differences In principle, but in the availability of the former at vastly greater distances and under all weather conditions, That such a radical change in navi- gation has been 'so quickly adopted by marines is proof of how success- fully It filled a long existing need. One master says "he would not sail a ship without a direction finder." Distance of Bearings Radio bearings are frequently tak- en at distances of 100 to 200 n1iles, and Ole possibilities a to distance ap- pear to be limited mainly by what is wort[ while In aavlgatioe, This system not duly greatly facllt• totes and safeguards the navigation of vessels in approaching the coasts and making harbor entrances, but It enables vessels to take bearings on each other when approaching in fog, and thus to avoid collision. This important use of radio bearings be•. tween ship and ship is already com- monly employed. There are import- ant possibilities in its further develop- ment through the use on ships of low automatic radio transmitters. The radio compass has made pos- sible some of the 111001 notable ocean rescues of recent years by giving a moans of locating the vessel In dis- tress through radio bearings. In a number of great rescues In the north Atlantic there is a strong probability that the radio compass alone made It possible to find the sinking ships and rescue the crews. The radio beacons may bo placed at any lighthouse or on any lightship at reasonable cost and the expense of maintenance is moderate, as no addl. tional personnel are required. This 0, therefore, a system which can ef- fectively cover an area of some 300 tImes as great. There is no present prospect, however, that the sound -in - air or signals can be dispensed with. There are others ways of using radio hearings in navigation, but the method stere briefly outlined, with he radio compass on the ship taking t 10001nga of radi0bea0ons or other 'adto signals; is the only possible get- 1 A Sun Dance Relic Old Indian Link with the Past Now at National Mus- eum at Ottawa Though it still belongs to the Black- foot Indians, an old, weather heat 011, painted buffalo skull, part of the al- tar of the Sun Mance Lodge, the most sacred 111uUtulton to tribosmml of mho old £0114, has been brought to tine, No- t)o01(1 110001110 in Ottawa. - Nothing connected 011 II the lodge could be given or said to anyone, the Indians said.
