This handbook gives a brief account of the principal insect and mite pests 
of crops in the Lesser Antilles. The author, who is entomologist on the Staff 
of the Dep’t of Agriculture, writes on the subject with authority. The object 
of the book is mainly educational for agriculturalists, and it shoidd answer the 
purpose for which it is intended, being indeed a creditable production, n.

The book represents the subject matter of a course of lectures given by the 
author to students at the University of Bern. It contains three chapters 
dealing with (i) Stinging, biting and injurious or rash-inducing arthropods ; 
(ii) Parasitic arthropods; (iii) Arthi’opods which transmit disease. The 
illustrations, mostly borrowed from other authors, ai’e on the whole fair, 
though they have suffered in the process of reproduction. The booklet can 
be recommended as an introduction and cursory review of the subjects of 
which it treats. N.

This is a remarkable and original book, well written and well illustrated, 
and full of information which cannot be found in more pretentious works. 
The author has discarded useless lumber and confines himself to what is 
useful to-day. It is a book that should be in every laboratory dealing with 
histology, zoology, botany and parasitology. We heartily congratulate both 
author and publisher on its appeai’ance. N.

The rapid increase in our knowledge of the trypanosomes is well evidenced 
in the present edition, which contains no less than 1000 pages—an increase of 
582 pages on the first edition, published in 1904. 
The book is divided into a general part, the greater poi'tion of which is 
new, and a special part containing chapters on the various trypanosome 
infections of vertebrates and invertebrates, and finally an appendix on the 
invertebrate carriers. LTnfortunately, the book lacks an index—a great 
necessity in such a voluminous work—and we would earnestly draw the 
attention of the authors to this omission which should be remedied in future 
editions. 
The second edition of this monumental treatise contains references to all 
the literature up to date, and no one concerned with trypanosome research 
or working in trypanosome-affected countries can afford to be without it. h.
