named above, which proportions the chemist cannot fully deter- 
mine. ‘The ethers of wine elude quantitative analysis. More- 
over there are doubtless substances in wine not identified. It 
may be perfectly true that a mixture of pure alcohol, water, glu- 
cose, bitartrate, and ethers, may be made in such carefully 
adjusted proportions that it will probably be capable of producing 
whatever effect wine would produce upon the system, and indeed 
may be less objectionable for administration, more agreeable, 
and more saleable than are many grades of actual wine; yet 
such a mixture is not actual wine, and should not be presented 
as such.” 
In treating of malt liquors, the author does not endorse the 
view that strychnia, if added to beer, would be thrown out of 
solution by the tannic acid of the hop. The tannin of the hop 
does not remainin beer. ‘* Moreover the insolubility of the tan- 
nate of strychnia in 20,000 parts of water is by no means assured, 
and with the solvent action of acetic acid, as in beer, is quite 
improbable.’’ Further, where strychnia is used, the hops will 
either be greatly reduced in amount or dispensed with altogether. 
We may finally characterise this work as a valuable comple- 
ment to the labours of Mr. Allen, Professor Wanklyn, and 
others of the much-abused public analysts who are successfully 
striving to place the chemical examination of food upon a sound 
and sure basis.

Tuis is a decidedly unreadable book, and yet as a work of refer- 
ence we must pronounce it a most valuable contribution to 
geological literature—a store-house of authenticated facts placed 
at the disposal of men of science. 
After a historical sketch of the progress of mining and metal- 
lurgy in the State of Missouri, we find an account of its caves, 
water-supplies, soils, timber, minerals, and rocks. Then follow 
more detailed notices of the geology of the various counties, and 
a description of the lead regions of south-western and of central 
and south-eastern Missouri, and of the iron ore deposits of the 
State. In the appendices are given a description of the lead- 
mines of upper Louisiana, the metallic statistics and mineral 
springs of Missouri, and an abstract of the chemical analyses exe- 
cuted by the department. These latter refer chiefly to coals, 
limestones, waters, lead and zinc ores, and slags. 
The presence of cadmium in the blende from the south-western 
region is a fact of some interest. In its determination the 
samples usually taken were of the weight of 20 grms. The cad- 
Mmium was first thrown down by means of sulphuretted
