KA rURE 



[October 17, 1S9: 



gla^s. losses up to as much as four-iiHu~ m; ur- uhole electrifica- 

 tion were sometimes oliserveil, hut never complete iliselectrifica- 

 tion. The results, however, were ver)- irregular. Xon-electrifieti 

 air never became sensibly electrifietl by lieing drawn through the 

 hot glass tubes in our experiments, but it gained strong positive 

 electrification when pieces of copjwr foil, and negative electrifi- 

 cation when pieces of carlxjn, were placeil in the tube, and when 

 the teni]x;rature was sufticient to jiowerfiilly oxidise the copjier 

 or to burn away the charcoal. 



§ 12. Through the kindness of Mr. E. Matthey. we have been 

 able to experiment with a platinum tube i metre long and I 

 milimetre bore. It was heated either by a gas flame or an 

 electric current. When the tube was cold, and non-electrified 

 air drawn through it, we found no signs of electrification by our 

 receiver and electrometer. But when the tube was made rett or 

 white hot, either by gas burners applied externally or by an elec- 

 tric current through the metal of the tulje, the previously non- 

 electrified air drawn through it was found to be electrified 

 strongly jxjsitive. To get complete command of the temperature 

 we passed a mea.sured electric current through 20 centimetres of 

 the platinum tube. On increasing the current till the tube Iwgan 

 to be at a scarcely visible dull red heat, we found but little elec- 

 trification of the air. When the tube was a little warmer, so as 

 to be quite visibly red hot, large electrification became manifest. 

 Thus 60 strokes of the air-pump gave 45 scale divisions on the 

 electrometer when the tube was dull red, and 395 scale divisions 

 (7 volts) when it was a bright red (produced by a current of 36 

 amperes). With stronger currents, raising the tube to white-hot 

 temperature, the electrification seemed to be considerably less. 



UNIVERSITY AND EDUCATIONAL 

 INTELLIGENCE. 



Oxford. — There are few changes of imixjrtance in the lists 

 of lectures issued by the Board of Faculty of Natural Science 

 fca Academical year. 



I'rof. Cntch h.ts come into permanent residence, and has 

 ap|V)intcd Dr. (iustav Mann, of Edinburgh University, to be 

 Demonstrator in I'hysiologj-, in place of Dr. I'embrey, who has 

 been appointed Lecturer in I'hysiole^' at the Charing Cross 

 Hospital.

 I'rofess<jr of Medicine is appnaching completion, and Dr. J. 

 Ritchie will give a course of practical Tathologicil Bacteriology 

 for the Regius Professor. The present pathological laboratory 

 is on a mo<lest scale, and it is hoped that before long the Uni- 

 versity will Iw in a position to afford a building and equipment 

 more worthy of the growing needs of the medical school at 

 Oxford. 



The examination for the Burdelt-Coutts" Scholarship is to

 College on December I, 1895, and in addition the Warden and 

 I'ellows have power to give exhibitions of Cyi to £,a,o a year. 

 No papers in Natural Science will lie set, but in the case of one 

 of the exhibitions preference will \k given to any candidate who 

 shall undertake to read for honours in Natural Science, and to 

 proceed to a degree in Medicine in the University of Oxford.

SCIENTIFIC SERIALS. 



Aiiieritaii Journal of AfatluiiialiiS, vol. xvii. No. 4 (Baltimore, 

 October). — On the deformation of thin ela.stic wires, by \. B. 

 Basset. In the author's previous iK»|X'r (vol. xvi. ) im the 

 deformatiiui of thin elastic plates and shells, whilst commending 

 the novelty, power and elegance of the :;(omclriial investigations 

 employed in Mr. I.ove's treatise on elasticity, he impugned the 

 treatment of the //yti'o// portion of the subject. It is on the 

 same ground of defective treatment that Mr. Ha,sset considers 

 that a further expiisition on the theory of wires is needed, and 

 this is what is furnished In the present paper. A useful table of 

 contents precedes the text. — Investigations in the lunar theory, 

 by Prof. E. W. Brown, is a memoir to which reference lia-s 

 already been m.iile in oiu' colunms (No. 1352, p. 533). The 

 closing |ia|>er is by Otto Staude, " Uelwr den Sinn der Windung 

 in den ninguliircn Puncteii ciner Raumcurve,"
