It will be seen from the foregoing statement regarding the contents of the 
work that it departs from the usual order ado23ted by authors in 23reseiiting a 
subject to readers. There is really no S 2 :)ecial order about the book—it is 
com 2 )osed of a series of disconnected treatises in which an attem23t is made, 
with more or less success, to summarize our 25resent knowledge. Some of the 
views of Hartmann on classification are by no means likely to meet with 
general acce23tance. The “ Chlamydozoa,” about which there has been much 
controversy, are treated very fully. Some of the authors base their opinions to 
a great extent iqjon ingenious hjqjotheses and “ Hilfshy 2 J 0 thesen,” consequently 
the book is scarcel}" one to be commended to workers commencing the study 
of 2 )rotozoology. The work is, nevertheless, valuable for the many suggestions 
it contains—suggestions which will doubtless influence future im'estigations. 
The text is excellently illustrated, and co23ious references are given to the 
literature, n.

As stated in the introduction, the object of this book is to bring to 2 )iiblic 
notice the necessity for the reduction of domestic mosquitoes and to describe 
how this is best effected. The book is consequently' not overburdened with 
detail and written with a view to familiarizing those in authority with the 
2 )ractical im 2 )ortance of mosquito reduction. The twelve chapters into which 
the book is divided deal with the importance of domestic mosquitoes and their 
biology; the fever census; estimating the cost of mosquito reduction; the 
manner of starting anti-mosquito cam23aigus and observing their effect.
