The transformations of the animal world, C. Dki'ekkt (Nciv Yoh-Jc, 1909, 

 pp. XY 1+360). — In the first part uf the book the author gives a summary of 

 the work of the principal authors regarding the evolutionist theory, including

 deals with the different processes of the variation and the extinction of species, 

 together with the effects of migrations and the problem of the first appearance 

 of life on the globe. 



The origin of vertebrates, W. H. Gaskell {London and Neio York, 1908, 

 pp. IX+5.37, pgs. KiS; rcr. in Science, n. scr., 29 {1909), No. 751, pp. 816-S18).—

Inoculating wolves {Breeder's Gaz., 55 {1909), No. 20, p. 166).— B. J. Peter- 

 son states that a large number of coyotes and jack rabbits severely affected with 

 mange have been killed in Nebraska, and M. E. Knowles, Montana state vet- 

 erinarian, that reports from southern Wyoming indicate that the mange of 

 coyotes has spread to that section. H. Avare, Montana state game and fish 

 warden, re[)orts that due to a crusted snow about 2C»0 deer were killed during 

 the winter of 1908-9 near Ovando. Reports were received from other sections 

 of the State to the effect that coyotes were killing deer at a rate that threatens 

 their extincion. 



Rabbit destruction, G. M. McKeown {Agr. Gaz. N. S. Wales, 20 {1909),

 with a bibliography of 40 titles, is given. 



"Owing to the differences in altitude, tempei'ature, etc., the study of bird 

 migrations is more complicated than in more level regions, there being a sort of 

 vertical migration as well as the regular northward and southward movements. 

 Valuable notes on vertical migration a few miles south of this county were made 

 by Mr. T. M. Tripp." 



List of injurious and beneficial insects and other animals received during 

 1908, .J. AV. SnoEBOTHAM {Jour. Cooper Research Lab., 1909, No. 1, pp.
