_A Series of Questions Pertaining to the Curriculum of the Dental Student._--Embracing Dental Histology, Dental Pathology, Dental Surgery, Dental Prosthesis, Dental Metallurgy, Dental Materia Medica and Therapeutics, Anatomy, Physiology and Chemistry. By Ferdinand J. S. Gorgas, A. M., M. D., D. D. S., University of Maryland. Publishers: W. K. Boyle & Son, Cor. Baltimore and St. Paul Streets, Baltimore, Md. 1885. Price, $1.50. This work comprises leading questions on all the branches belonging to the course of study pursued by the dental student, and its object is to facilitate the study of dental science and its collateral sciences. Some years ago the author published a small work embracing in an abridged form, questions on Dental Science, and the favor with which it was received by the students of his class, was such as to rapidly exhaust the limited edition, and induce him to prepare, when opportunity offered, a more complete series of questions embracing the entire curriculum of the dental student, and even that of the medical student so far as related to Anatomy, Physiology and Chemistry. The present work, therefore, is the result of such an intention, and is presented with the hope that it may accomplish the object for which it has been prepared. * * * * * _Practical and Analytical Chemistry._--Being a Complete Course in Chemical Analysis. By Henry Trimble, Ph. G., Professor of Analytical Chemistry in the Philadelphia College of Pharmacy. Illustrated. Publishers: P. Blackiston, Son & Co., Philadelphia. 1885. Price, $1.50. The object of this excellent work is to place before the student of pharmacy and medicine a compact course of analytical chemistry. The distinguished author believing that the study of Qualitative Analysis should be preceded by some practical experience such as relates to the preparation of the important gases and a few of the salts, devotes Part First to the consideration of Hydrogen, Chlorine, Hydrochloric Acid, Oxygen, Nitrogen, Ammonia, Nitric Acid, Carbon Dioxide and the preparation of such salts as Potassium Chloride, Potassium and Sodium Tartrate, Ammonium Nitrate and Oxalate, Calcium Phosphate, Magnesium Sulphate, Carbonate and Oxide, Aluminium Hydrate, Ferrous Sulphate, Ferric Sulphate and Hydrate, Copper Sulphate and Lead Acetate. Part Second is devoted to Qualitative Analysis, and Part Third to Quantitative Analysis, together with a description of apparatus, and the processes of filtration, evaporation, crystallization, ignition, etc. The work extends over nearly one hundred pages, and is a valuable text-book for the student. * * * * * _Chemical Problems._--By Dr. Karl Stammer. Translated from the second German edition, with explanations and answers, by W. S. Hoskinson, A. M., of Wittenberg College, Ohio. Publishers: P. Blackiston, Son & Co., Philadelphia. 1885.
