Moore’s Bacteriology.’ 
in the form of mimeograph sheets for the use of students in the bac- 
teriological laboratory at Cornell University, and its statements have 
consequently been tried in the fires of actual use. Now that these 
directions have been printed in a simple and inexpensive form, it is 
to be hoped that they will find their way into many schools and 
laboratories where bacteriology is studied. No claim is made to 
completeness or infallibility, but at the same time it would be diffi- 
cult to find anywhere in the world, in the same number of pages, 
as many important and useful suggestions. Dr. Moore’s courses in 
bacteriology in the veterinary school at Cornell are among the very 
best in the country, and this book is to be welcomed as an extension 
of the influence of a conscientious teacher who is at the same time 
a competent investigator. The book contains 89 pages, beginning 
with the cleaning of glassware and ending with the bacteriological 
examination of water. It is arranged in 59 chapters, designed for as 
many separate laboratory exercises. Migula’s system of classifica- 
tion is adopted. The occasional imperfections and omissions will 
no doubt be rectified in subsequent editions, of which we trust there 
may be many.

Monographie der Myristicaceen.* — In few even of the tropical 
groups of plants have generic lines been so poorly understood as in 
the Myristicacez, the nutmeg family. From time to time attempts . 
have been made to separate from the large and evidently heterogene- 
ous Myristica various independent genera, but hitherto the herbarium 
materials of the whole family have been so fragmentary, and the diffi- 
culty of constructing from them a satisfactory group of genera so 
great, that even in 188o it still seemed best to Bentham and Hooker 
to treat the whole family as a single complex genus 
For some years Dr. Otto Warburg, of the Botanical Museum in 
Berlin, has been engaged on an exhaustive revision of this confused 
group, and his completed work, now before us, shows that the task 
could not have fallen into better hands. The monograph (filling a 
thick folio of some 680 pages) is of a kind that only Germans have 
patience to prepare. A liberal space has been allotted to the treat-
