The Teachers' School of Science, estab- 

 lished by the Lowell Institute of Boston, offers 

 this winter, as a new departure, a course of 

 fifteen lectures to teachers, on the funda- 

 mental principles of physical chemistry, dis- 

 cussed with special reference to their applica- 

 tion in the teaching of elementary science. 

 The lectures will be given by Professor G. N. 

 Lewis, of Massachusetts Institute of Technol- 

 ogy, on Saturday forenoons, beginning No- 

 vember 16. This course is offered at the re- 

 quest of the New England Association of 

 Chemistry Teachers and will be open free of 

 charge to all science teachers. 



Nature states that the Philosophical Insti- 

 tute of Canterbury, New Zealand, is making 

 arrangements for an expedition to some south- 

 ern islands included in the colony's bound- 

 aries. The expedition will be under the lead- 

 ership of the Hon. R. McNab, minister of 

 lands and minister for agriculture, who is 

 interested in the history of the islands, and 

 has written an interesting work dealing with 

 the old sealing and whaling days in the islands 

 and the southern part of the mainland. The 



expedition will be under the auspices of the 

 government, and will be taken to the islands 

 in one of the government's steamers. It will 

 leave New Zealand about the end of Novem- 

 ber or the beginning of December, and will 

 visit the Auckland Islands and Campbell 

 Islands. About twenty New Zealand men of 

 science will take part in the undertaking. 

 They will be divided into two parties, one 

 going to each group. Work will be done in 

 regard to terrestrial magnetism, zoology, geol- 

 ogy and botany, and reports will be prepared 

 dealing with the results of the investigations. 



The report of the Departmental Committee 

 appointed to inquire and report as to the 

 nature and extent of the benefit accruing to 

 British arts and industries from the participa- 

 tion of Great Britain in great international 

 exhibitions, has been issued as a parliamentary 

 paper. According to an abstract in Nature, 

 the committee found that the evidence it re- 

 ceived went to show that international exhibi- 

 tions are of little use to the textile and other 

 great staple industries of the country. The 

 committee is, however, in favor of the con- 

 tinued participation of this country in all 

 really important exhibitions, owing to the in- 

 direct advantages resulting. One aspect of 

 exhibitions to which considerable importance 

 should be attached is the effect which they 

 have in encouraging national emulation and 

 in stimulating individual exhibitors to improve 

 their productions. Examples of the effects 

 which particular exhibitions have had on the 

 development of different industries will be 

 found in the evidence of Sir William Preece, 

 K.C.B., Mr. Bennett Brough, and other wit- 

 nesses. Sir William Preece attributes to the 

 Paris Exhibition of 1881 many of the most im- 

 portant developments of the electrical in- 

 dustry. The exhibition at Paris of certain 

 high-speed tool steels by an American firm is 

 said by Mr. Bennett Brough to have con- 

 tributed in a large degree to the development 

 of what has become a British industry of great 

 magnitude; and an exhibit by the Courrieres 

 Colliery Company, at the mines of which the 

 death-rate from falls of roof was abnormally 

 low, has since led to considerable improvement
