2. Report of the IT. S. National Museum. Pp. xv, 598. Wash- 

 ington, 1901. (Annual Report of the Board of Regents of the 

 Smithsonian Institution, showing the operations, expenditures, 

 and condition of the institution for the year ending June 30, 

 1899.) — The report of the Secretary of the Smithsonian Institu- 

 tion lor the year ending June 30th, 1899, was announced in the 

 last number, p. 400. We have now the accompanying report of 

 the U. S. National Museum giving the account of additions to 

 the museum and other related points for the same period, by 

 the Assistant Secretary, Mr. Richard Rathbun; to this are added 

 also the reports of the Head Curators. Of the accompanying 

 papers, forming Part II, the most extensive (pp. 153-483) is that 

 by Mr. George P. Merrill, entitled a Guide to the Collections in 

 the Section of Applied Geology in the National Museum ; the 

 Non-metallic Minerals. This paper, also published as a separate 

 volume, contains much more that is interesting and of general 

 value than might be anticipated from its title, since the author 

 has brought together a large amount of material, much of which 

 is new, particularly in regard to the occurrence of species 

 described. Accompanying these descriptions are numerous plates 

 showing quarry exposures, specimens of striking character, and 

 other similar points. Two other interesting papers in the volume 

 are by O. T. Mason on ethnological subjects. 



3. The Journal of Hygiene. Edited by George H. F. Nuttall 

 in conjunction with John S. Haldane, and Arthur Newsholme. 

 Vol. i, No. 1, pp. 152. (University Press, Cambridge ; price live 

 shillings.) — This new journal, to fee published quarterly in vol- 

 umes of about 500 pages, has been established to fill the obvious 

 need of an English publication containing original contributions 

 on the subject of hygiene. It will embrace papers oh all the 

 different scientific lines which converge upon this department, 

 and will also include discussions of administrative and practical 

 questions. Of the papers contained in this number may be men- 

 tioned the following : two studies of the Anopheles and its distri- 

 bution in England, in relation to malaria ; another on pathogenic
