VII occupies pages 1—27, following which are two appendices. 

 Appendix A is devoted to a study of special cloud forms, by 

 A. E. Sweetland, especially as regards their relations to cyclones 

 and anti-cyclones, to precipitation, and temperature changes. 

 Appendix B, by S. P. Fergusson, gives an interesting discussion 

 of the results obtained by the exploration of the upper atmosphere 

 by means of kites. The special forms of kites are described, as 

 also the registering meteorological apparatus carried by them. 

 The results obtained thus far show the value of this new method 

 of meteorological research.

 Basel (Georg et Cie), 1898. — In these two volumes are collected 

 the addresses and smaller essays of the Swiss naturalist Kiiti- 

 meyer, who is best known for his works on vertebrates, recent and 

 fossil, but chiefly mammals, and who died in 1895. They are 

 mainly written in popular style, and some of them are still inter- 

 esting reading, though reflecting the views of the older school of 

 naturalists. The following are a few of the titles of the papers : 

 On the form and history of the vertebrate skeleton ; on the his- 

 toric method in paleontology. The limits of the animal world, a 

 discussion of Darwin's theory. On the nature of progress in the 

 organic creation. From the sea to the Alps, descriptions of the 

 structure, form and color of our continent upon a section from 

 England to Sicily. A sketch of the history of glacier-studies in 

 Switzerland. Sketches of the lives of Agassiz, of Charles Dar- 

 win, of Bernhardt Studer, etc. 



His more important scientific works were on Ruminants (Bos, 

 Deer. Equidae, etc.), and on the fossil turtles. h. s. w. 



4. Transactions of the American Microscopical Society. Ed- 

 ited by the Secretary. Volume xix, pp. 207, Buffalo. — The vol- 

 ume just issued, bearing date of December, 1897, contains the 

 proceedings of the American Microscopical Society for the twen- 

 tieth annual meeting, held at Toledo, Aug. 5th, 6th and 7th, 

 1897. It includes an address by the President, E. W. Clay pole, 

 entitled, "Microscopical Light in Geological Darkness," which 

 discusses sonie of the ways in which the recent work with the 

 microscope, especially in petrography, has served to throw light 

 upon obscure geological problems. A series of valuable papers 

 follow, chiefly on biological subjects.

 zweite Halfte, 2 Lieferung, Leipsic, 1897 (Wilhelm Engelmann), 

 — Two previous parts of this valuable text-book on physical, 

 chemical and biological science have already been noticed in 

 this Journal (vol. ii, p. 450). The present part, comprising 

 pages 593-944, maintains the high standard of excellence and 

 fullness that characterized the earlier issues. The scope of 

 the work has been somewhat enlarged beyond the original plan,
