Publication 159. The Lord Baltimore Press, Baltimore, Md., TJ.S.A. 26 x 18 cm. 
Volume II contains 150 plates. 
The first copies of this monumental work were issued 21 Jan. 1913. The 
two volumes represent work commenced in 1903 with the aid of grants from 
the Carnegie Institution of Washington, and from the U.S. Dept, of Agriculture 
etc. ; a part of the expense was defrayed by two of the authors, Messrs Dyar 
and Knab. Many volunteers have however helped in the work of collecting 
material. A number of paid investigators were sent to different localities to 
collect specimens and make studies upon the biology of various species of 
mosquitoes. The authors themselves travelled extensively for the purposes of 
the investigation and Dr Howard went to Vienna to examine the Wiedermann 
and Winthem types.- 
The authors condemn the genus Stegomyia , the familiar S. fasciata disappears 
in favour of Aides calopus. The so-called Anopheles macidipennis (of America) 
is now A. quadrimaculatus and A. occidentalis. Culex fatigans or C. cubensis 
becomes C. quinquefasciatus etc. The authors give a great deal of valuable new 
information on bionomics. 
Following upon an historical introduction the anatomy of mosquitoes in all 
stages is described, then follow details regarding their biology, enemies, 
methods of collecting mosquitoes, their relation to disease, remedies against 
mosquitoes with examples of mosquito control in different parts of the world. 
Whilst quoting extensively from difierent authors, due credit is given to others 
for the work they have done. The bibliography occupies 37 pages and a very 
full index concludes the volume. 
Volume II includes the plates of which there are no less than 150. Of these 
39 illustrate the external male genitalia (270 figs.); 1 the wings, 43 the larva 
seen in toto, 58 details in the structure of larvae, the remaining plates illus¬ 
trating a few of the eggs and pupae of different species. The illustrations of 
the larvae are exceptionally beautiful, they were executed by one of the authors, 
Dr F. Knab, a fact which we did not find mentioned in the text. Altogether 
we have before us a most excellent publication upon which the authors are to 
be congratulated most heartily, n. 
Ross, H. C., Cropper, J. W., Ross, E. H. and others (iv. 1913). Researches into 
Induced Cell-reproduction and Cancer and other papers. Vol. III. (The John 
Howard McFadden Researches.) London : John Murray, Albemarle Street, W.

This volume consists of a collection of papers including such diverse 
subjects as “The Problem of the Gasworks Pitch Industries and Cancer,” 
“ Protozoal Parasites found in Syphilis,” and the cultivation of trypanosomes. 
Many of the articles have been previously published elsewhere. 
The descriptions of parasites seem to be based mainly on the appearances 
presented by films prepared by the so-called “jelly method,” whilst, in the case 
of those papers dealing with malignant growths, the theory of auxetics is called 
in to explain their origin. The descriptions of the life-cycles of the Lympho- 
cytozoa are of a highly speculative character and very unconvincing, and before 
accepting the theories advanced by the authors independent confirmation is 
much to be desired.
