experiment station for plant pathology of the agricultural bureau of Saxony. 
e work is compiled from all available sources, American methods 
being extensively quoted. It devotes three pages to preparations in which 
the chief ingredients are of animal origin, such as fish oil, lard, soap and 
glue ; twenty pages to those with vegetable substances, such as cotton-seed 
and other plant oils, resin, tar, pyrethrum, tobacco and hellebore; and the 
remainder of the work, 141 pages, to those with mineral ingredients. 
Although primarily a volume of recipes, the metric system of weights and 
measures being exclusively employed, yet their uses and methods of appli- 
cation are clearly and succinctly set forth, with an estimate of their efficiency, 
-and references to the source of information. 
The work is admirably conceived and executed, and as closely up to 
date as any general work is likely to be. The classification makes it handy 
for reference, which is further aided by a full index.—J. C. A 
Bryology of Madagascar. 
SINCE THE publication in 1879 of Bescherelle’s Florude bryologique de la 
Réunion et autres tiles austro-A fricaines de 1’ Océan Indien, a number of papers 
on the mosses of Madagascar and allied regions have been published by 
Miiller, Bescherelle, Brotherus, Wright, Mitten, Warnstorf, Renauld, and 
Cardot. Collections by French officials, missionaries, and others have accu: 
mulated. M. F. Renauld has sought to bring all this scattered information 
together in a sumptuous volume published by order of Prince Albert of 
onaco.° 
In preparing this work he has had abundant cooperation of bryologists 
who have been working in this field, or those who have charge of collections 
from South Africa, A preface on the generic nomenclature and the value 
Specific characters contains nothing novel. The geology, topography, : 
climate of the islands are briefly described. The chapter on the distribution : 
of the mosses is very unsatisfactory because knowledge of the region is still 
much too imperfect to allow adequate treatment. M. Renauld calls the 
bryological flora south tropical; holds that the islands constitute an inde- 
pendent domain, each island having its own individuality but unequally 
_ marked; and sees relations on the one hand with the flora of the In os - 
Javanese archipelago through allied species, and on the other with that 
the mountains of South Africa both by allied and by identical species. 
The flora of the whole group is enumerated as follows: Acrocarp! 413,
