The 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.

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. careignes et des Comores, public par ordre de S. A. S. le Prince Albert 1er.
