The Mesozoic beds of Virginia are all situated east of the Blue Ridge, and most of them are found within the terrain of the crystalline Azoic rocks. The beds are divided into two classes, which appear to have but little in common with one another. The older Mesozoic beds, which furnished the plants described in this book, are of freshwater 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 beds, and for the sake of comparison with them, plates and descriptions are given from Emmons's work of plants from the older Mesozoic strata of North Carolina, most of which, however, coming from strata above the coal, are supposed to be of a somewhat later age than the Virginia plants.

this issue, which forms No. 17 of the Q. P. series, the numbers for 1884 of fifty periodicals, and of the United States consular reports and education circulars, are indexed. The list includes all the important American literary magazines and reviews, most of the British literary magazines which have a circulation in this country, and about a dozen German periodicals. The "Revue de Belgique" 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 seventy-five thousand 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 efficiency. He is also a spelling reformer who has the courage of his convictions, for he writes "forein," "welth," "tarif," "primitiv," "fotografy," "iland," etc.

edition of this work now publishing is to appear in three volumes instead of two, as in the first edition. A new arrangement of the subject-matter has been adopted, so that each volume may treat more especially of kindred products. The volume now presented is devoted chiefly to the consideration of bodies of the fatty series and of vegetable origin, and includes chapters on the alcohols, ethers, and other neutral 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 treatment of the rest of the work.

book discusses in a clear and readable style one of the severest afflictions to which man is liable. 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 troubled, lie begins with a full chapter on "The Nature and Cause of Sleep," which is followed by the consideration of the immediate 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 Somnambulism, or Hypnotism."

nine hundred and fifty-three tests are described briefly under the names of the originators, which are arranged alphabetically, and a subject-index is added. The very common tests are not included.
