CHEMISTS’ BUILDING. The Chemists’ Building Company of New York City, organized to promote the interests of Chemical Science and Industry in America, has erected a ten-story &e-proof building, on a lot 56 it. wide and I W it. deep, a t 50-54 East qist Street, New York City. The lower half of the building is leased to the Chemists’ Club, and contains all the appurtenances a i a social club, together with a large auditorium for scientific meetings and ample space for a complete chemical library and museum. The five upper stories have been specially constructed for laboratory purposes, and can be rented either as cntire floors, or in suitablc sub-divisions, to analytical, commercial or research chemists, physicists, electrochemists, bacteriologists, etc.; but not as manufacturing laboratories. They are provided with ventilating flues, water, gas and electric mains, steam and compressed air lines, in suitable locations; but the tenants are expected to make their own connections and provide their own fixtures. Rental will includc free janitor and elevator service, heat and clectricily for lighting purposes, and the Company will construct proper partition walls for the subdivision of the laboratories, according to the tcnants‘ wishes. I t is intended to charge low rentals and in many way facilitates the prosecution of scientific and industrial research. Locntion.-Close to the Grand Central Station and the q m d Street Express Station of the Subway, as well as to the praspective tcrrnini of the ”Steinway” and “McAdoo” terminal systcms; a few minutes’ w d k from the New York PublicLibrary, Engineering Society’s Building and Academy of Xedicine.

Adzanluges within the Building.-Excellent light and ventilation; construction equal to that of university laboratories; command of a complete chemical library; opportunities for social and scientific intercourse ; the natural meeting-place of out-of-town chemists and manufacturers, for whom the Club provides excellent apartments; possibility for reduction of laboratory expenses through cooperative installation of expensive apparatus.
The value of this neighborhood for such purposes has been further indicated by the erection of a large physicians’ and dentists’ building alongside, and the attention of physicians and pathologists is called to the advantages which the Chemists’ Building laboratories could afford them for their own researches. Until February Ist, communications should be addressed to Dr. Morris Loeb, President, 106 West 55th Street. After that date, his office will be in the Building, 5 0 East 41st Street.

view of the many questions coming up under the Food and Drugs iict the data found in this section of the book should be appreciated. Professor Kraemer has devoted much study to the microchemistry of drugs and methods of identification. I n Part IV the newcr developments in this field are discussed; the opinion is expressed that the petrographical microscope will prove as useful in the study of the crystalline constituents of drugs as it has in other directions. The value of this general method is illustrated by the details of a number of practical examinations on well-known crystals which occur in certain drugs. The method of securing the crystals is explained and enough is presented to make the general plan of identification helpful and suggestive to the drug analyst. J. H. LONG.
Intended for the A Text-Book of Botany and Pharmacognosy. Use of Students of Pharmacy, as a Reference Book for Pharmacists, and as a Hand-Book for Food and Drug Analysts. By HEXRYKRAEMER,Ph.D., Ph.B. 888 pages, illustrated, 4th edition, revised and enlarged. Philadelphia: J. B. Lippincott and Co. 1910. Price, $5.00 net. This book is well known in schools of pharmacy where for some years it has been recognized as a standard work, while the nature of the book makes it naturally of somewhat limited interest to chemists: it possesses certain features which deserve more than a passing notice in this place. The work is divided into four parts: Part I , in five chapters, covers the general subject of botany as related to medicinal plants; P a r t I1 is concerned with a study of crude drugs as derived from these plants, while Parts I11 and I V , which are much shorter than the others, deal with reagents and technique and methods of microchemical analysis. I n Part I1 there is a great deal of information on this subject of plant constituents which will be found very useful to any one interested in the chemistry of drugs and drug analysis. In
