more pronounced. The diagnosis of paretic dementia seemed natural 

 under the circumstances. The patient had been a chloral faker and said 

 he had used "tons of the stuff." While under the author's care in the 

 hospital, either that drug, sulfonal or other hypnotics were employed to 

 retain the nervous excitement for the time being. Under a suspicion that 

 the case was one of chloral habit, all hypnotics were withdrawn. Four 

 weeks later he was himself again.

Atlas of Methods of Clinical Investigation with an Epitome of Clinical Di- 

 agnosis a?id of Special Pathology and Treatment of Internal Diseases. 

 By Dr. Christfried Jacob. W. B. Saunders, Philadelphia. 

 Saunders' Medical Hand Atlases are in many ways remarkable books. 

 "Well gotten up, well printed and bound, convenient in size and form and 

 remarkably reasonable in price. We have often been surprised to find 

 that books of such rich illustration could be published for the price. The 

 present volume is an addition to any technical library. For the student of 

 medicine it is invaluable ; the practising physician should certainly have 

 it, or have access to it. For the pharmacist who is entering into clinical 

 work to aid the doctor in accurate diagnosis, it is a very valuable work, 

 though for this class of workers its use is restricted to about one-third of 

 the book. For him, however, the illustrations of the blood, normal and 

 diseased, parasites in the blood, blood spectra and blood crystals, micros- 

 copy of the mouth and nasal cavities, microscopy of the sputum, the 

 parasites of the sputum, microscopy of contents of the stomach and intes- 

 tines, the most important color reactions of the gastric juice, urinary sedi- 

 ments, crystalline urinary deposits, organized urinary deposits, urinary 

 tube casts, urinary sediments in kidney and bladder diseases, the most 

 important color reactions of the urine, demonstration of some medica- 

 ments in the urine, contents of cysts, abscesses, etc., some important pyo- 

 genic organisms. These and some others are very valuable. 



The text of the work is short and to the point, the translation is excel- 

 lent and the book is really a very excellent one throughout. 



Elements of Sanitary Engineering . By Mansfield Merriman. Profes- 

 sor of Civil Engineering in L,ehigh University. John Wiley & Sons. 

 New York and London, 1898. 



Though written from a technical engineering point of view, this little 

 book of some two hundred pages is in many ways a good common-sense 

 manual for others than engineers. The chapter on Sanitary Science, 

 Water and its Purification, Disposal of Garbage and Sewage are practical 

 and scientific. The book deserves a wide recognition.
