record output of 1910. Of this production, 

 5,135 tons were made from foreign ore. 

 Spelter stocks were reduced from 23,232 tons 

 to 17,788 tons. Imports remained about the 

 ■same but exports were nearly double those of 

 ialf the preceding year. The apparent consump- 

 tion of spelter was 135,497 tons, an increase 

 ■of more than 12,000 tons over the half of 1910 

 but about the same as in half of 1909. The 

 average price of spelter at St. Louis for the 

 period was 5.36 cents per pound, the London 

 average being .2 cent less per pound. During 

 the latter part of May and the first part of 

 June the average London price was about .1 

 cent higher than the corresponding St. Louis 

 prices. Under this stimulus the May exports 

 of spelter, zinc ore and dross were largely in- 

 creased over those of the preceding months. 



The Electrical World states that the Dan- 

 ish government, under the direction of its 

 biological department at Copenhagen, has 

 undertaken to aid the fisliSrmen of the Baltic 

 Ocean by preventing the migration of eels 

 from that arm of the sea into the outer ocean. 

 The means employed is a barrier of light, 

 formed by placing fifty electric lights along a 

 submerged cable between the island of Fano 

 and the coast of Funen. The eels migrate 

 only during the dark hours, and, accordingly, 

 as soon as darkness begins in the season of 

 migration the lamps are illuminated and a 

 wall of light is thus interposed which the eels 

 are fearful of passing. A similar plan, using 

 submerged lamps, is said to be a favorite re- 

 sort of Italian fishermen to keep eels from 

 leaving the shallow waters. 



The account in the July issue of Man, by 

 Miss A. C. Breton, of some of the museums 

 of archeology and ethnology in America, will 

 excite among British students of these sci- 

 ences mingled feelings — admiration at the 

 enterprise and liberality of the American 

 people, and regret that the contrast between 

 the institutions of America and those in 

 England is so clearly to our disadvantage. 

 The museums described in this paper are the 

 New York Natural History Museum, the 

 Brooklyn Institute, the Peabody Museum of 



Harvard College, the Tale University Mu- 

 seum, the Philadelphia Academy of Sciences, 

 the National Museum at "Washington, and the 

 National Museum of San Jose, Costa Rica. 

 Practically all these representative collections 

 are provided with suitable buildings and ade- 

 quate staifs; each has its library, to which ac- 

 cess is readily permitted, and arrangements 

 are made by which the ofiicials usually spend 

 part of each year in field work, and are thus 

 in a position to supply to inquirers first-hand 

 information. — Nature. 



It is stated in Nature that the Eoyal Com- 

 missioners for the exhibition of 1851 intend 

 to put into operation at an early date a 

 scheme of industrial bursaries. The scheme 

 is as follows : The commissioners propose to 

 establish a scheme of industrial bursaries for 

 young men who, after a course of training 

 in a university or approved technical college, 

 desire to enter engineering, chemical, or other 

 manufacturing works. The bursaries are in- 

 tended to enable suitable applicants to tide 

 over the period between their leaving college 

 and obtaining remunerative employment in 

 industry. The value of the bursary will de- 

 pend on the circumstances of the candidate, 

 but will, as a rule, not exceed £100 a year. 

 A bursar will be elected in the first instance 

 for one year, but the tenure of his bursary 

 will ordinarily be prolonged for a second 

 year provided that the commissioners are 

 satisfied with the work done by the bursar 

 during his first year. In special circum- 

 stances a bursary may be renewed for a third 

 year. The appointments to the bursaries will 

 be made by the commissioners from among 

 candidates recommended by the authorities 

 of certain selected universities and technical 

 schools. In dealing with these recommenda- 

 tions, great weight will be given to evidence 

 that a candidate has the practical abilities 

 likely to lead to his advancement in manufac- 

 turing work, academic success alone being an 

 insufficient recommendation. The candidate 

 must be a British subject under the age of 

 twenty-five. The candidate must have been 

 a hona fide student of science for a term of 

 three years. The candidate must further sat-
