Oldkr Mesozoic Flora ok \'iRaisiA. liy William Mokuis Fontaine. Washinj;- ton : Government Piinting-Offico. Pp. 144, with Fifty-seven Plates.
The Sle.^ozoic beds of Virginia arc all Bituntcd east of the Blue Ridge, and most of them are found within the terrain of the crystalline Azoic rocks. The beds are di- vided into two classes, which appear to have but little in common with one another. The older Mcsozoic beds, which furnished the plants described in this book, are of fresh- water or brackish-water deposit, and often contain coals. The younger formations also contain plants, but of a totally different character from that of the plants of the older Mesozoic. The most important of all the beds passes about ten miles west of Richmond, and is about thirty miles long and six broad. It contains nearly all the coal and yields nearly all the plants found in the formation. Besides the plants found in these bods, and for the sake of compari- Bon with them, plates and descriptions are given from Emmons's work of plants from the older Mcsozoic strata of North Caro- lina, most of which, however, coming from strata above the coal, are supposed to be of a somewhat later age than the Virginia plants.
The Q. p. Index for 1884. Fourth annual issue. Bangor: Q. P. Inde^. Pp. 57. Price, $1.
In this issue, which forms No. 17 of the Q. P. scries, the numbers for 1884 of fifty periodicals, and of the United States con- sular reports and education circulars, arc indexed. The list includes all the impor- tant American literary magazines and re- views, most of the British literary maga- zines which have a circulation in this coun- try, and about a dozen German periodicals. Tiic "Revue de Bolgiciuc" is included, but not the " Revue des Deux Mondes." Since the British reviews were indexed in No. 16, they do not appear in this issue. When one realizes that about scvcnty-fivc thou- sand pages are indexed in these fifty-seven pages, it becomes evident that Mr. Griswold has brought the art of abbreviating to a wonderful state of cfTiciency. lie is also a spelling reformer who has the courage of his convictions, for he writes "forein," VOL. xxviii.— 9

Commercial Organic Analysis. By Al- fred 11. Allen, F. 1. C, F. C. S. Sec- ond edition, revised and enlarged. VoL I. Philadelphia: P. Blakision, Son & Co. Pp. 470. Price, $4.50.
The edition of this work now publish- ing is to appear in three volumes instead of two, as in the first edition. A new arrange- ment of the subject-matter hus been adopt- ed, :o that each volume may treat more especially of kindred products. The vol- ume now presented is devoted chiefly to the consideration of bodies of the fatty series and of vegetable origin, and includes chap- ters on the alcohols, ethers, and other neu- tral derivatives of the alcohols, sugars, starch and its isomers, and vegetable acids. In revising this volume, the author has made considerable changes and additions in order to bring the information contained up to the latest possible date, so that very few pages remain as they stood in the first edition. He promises as thorough treat- ment of the rest of the work.
Insomnia ; and other Disorders of Sleep, By Henry M. Lyman, M. D. Chicago : W. T. Keener. Pp. 239. Price, $1.50.

In the discussion the author covers an even wider ground than is indicated in his title, and considers all the phenomena of sleep, both normal and trou- bled, lie begins with a full chapter on " The Nature and Cause of Sleep," which is followed by the consideration of the imme- diate subject of the treatise — insomnia, or wakefulness, the remedies for it and the treatment of it in particular diseases ; and after this are given chapters on " Dreams," " Somnambulism," and "Artificial Somnam- bulism, or Hypnotism."
