A Manual of Chemical Analysis, as applied to the Examination of Medicinal 

 Chemicals and their Preparations. Being a Guide for the Determination of their Identity 

 and Quality, and for the Detection of Impurities and Adulterations. For the use of 

 Pharmacists, Physicians, Druggists and Manufacturing Chemists, anil Pharmaceutical and 

 Medical Students. Third edition, entirely rewritten and much enlarged. In one very 

 handsome octavo volume of 621 pages, with 179 illustrations. Cloth, $4.25. 



We congratulate the author on the appearance 

 of the third edition of this work, published for the 

 first time in this country also. It is admirable and 

 the information it undertakes to supply is both 

 extensive and trustworthy. The selection of pro- 

 cesses for determining the purity of the substan- 

 ces of which it treats is excellent and the descrip- 



tion of them singularly explicit. Moreover, it is 

 exceptionally free from typographical errors. We 

 have no hesitation in recommending it to those 

 who are engaged either in the manufacture or the 

 testing of medicinal chemicals. London Pharma- 

 ceutical Journal and Transactions, 188.3.

 Colleges and by Beginners. Second American from the third and revised English edition. 

 In one very handsome royal 12mo. volume of 372 pages, with 47 illustrations. Cloth, $2.50. 

 The chief object of the author of the present work i renders it unintelligible to the primary student 

 was to furnish one which was sufficiently elemen- j unless supplemented by copious verbal explana- 

 tary in the description of apparatuses, chemicals, i tions from the teacher. The Elementary Treatise 

 modes of experimentation, etc., so as to "reduce I of Dr. Clowes, examined with reference to the 

 to a minimum the amount of assistance required above claims, is found to be a great improvement 

 from a teacher." It is a generally recognized fact on other elementary works. A student who care- 

 that one of the most serious hindrances to the , fully reads this text will scarcely need the assist- 

 utility of many of the smaller text-books is the too ! ance of a tutor in following out any of the ex- 

 great conciseness of the language employed, which | periments described. Va. Med. Monthly, Ap., 1881.

cine. Dr. Ralfe is thoroughly acquainted with the 

 latest contributions to his science, and it is quite 

 refreshing to find the subject dealt with so clearly 



This is one of the most instructive little works 

 that we have met with in a long time. The author 

 is a physician and physiologist, as well as a chem- 

 ist, consequently the book is unqualifiedly prac- 

 tical, telling the physician just what heougntto 

 know, of the applications of chemistry in medi- 



and simply, yet in such evident harmony with the 

 modern scientific methods and spirit. Medical 

 Record, February 2, 1884.

It is probably the best manual of an elementary ! and then advancing to the analysis of minerals and 

 nature extant, insomuch as its methods are the j such products as are met with in applied chemis- 

 best. It teaches by examples, commencing with try. It is an indispensable book for students in 

 single determinations, followed by separations, chemistry. Boston Journal of Chemistry, Oct. 1878.
