733 closed Vessels. In the first essay Dr. Child sup and corroborates Mr. Darwin’s investigations in to the mode of fertilisation of orchids, but he adduces some important evidence in opposition to that author’s views to the effect that " Nature abhors perpetual self-fertilisation."" The second essay, which is an extremely interesting and important one, is in some sort a continuation of the same train of reasoning, the author being a decided opponent of the view that marriages of consanguinity are necessarily followed by deterioration or degeneracy of offspring. The third essay contains a clear summary of the well-known dispute between the panspermists and the heterogenists, which a year or two ago excited so much attention in France, and with the latter of whom Dr. Child appears disposed, as we gather from his last essay, to rank himself. We have much pleasure in recommending this volume to our readers.

Remarks upon the Causes of Consumption. By VALENTINE DUKE, M.D., F.R.C.S.I., L.K.Q.C.P.I. London : Longman & Co. Dublin : Fannin & Co. 1867. THIS is an excellent and valuable statement of the tubercular cachexia, and of the sanitary principles upon which the approach of consumption is to be arrested, and its development prevented. Phthisis is a disease of no special state, or country, or climate; and it is only by sound sanitary principles, acted on by individuals and communities, that this great destroyer is to be successfully resisted.

CATCH-PIT.
A NEW catch-pit and interceptor has been invented by Mr. Chesshire, of Newhall-street, Birmingham. It consists of an iron box, or tank, one corner of which is screened off by a coarse perforated iron sieve, which permits the aqueous fluid to pass directly into the drain, and retains its more solid
