THE AMEEICAN MONTHLY. 



[November. 



certainly was astonished on learning for 

 the first time that I had been precluded 

 in the observations which begat my paper 

 entitled Pscudo-Cyc/osis, published in the 

 last March number, and my delight was 

 increased on reading Dr. Wallich's ex- 

 tracts from his papers published so long 

 ago, at seeing that, excepting the hyphen 

 used by me, we both had coined the same 

 word as a name for the interesting move- 

 ment which we both had studied in the 

 Ai)Hvba. As I was in absolute ignorance 

 of Dr. Wallich's work done in the Old 

 World so many years ago, I am content, 

 as an humble worker in the New World, 

 of rediscovering and re-naming the 

 phenomenon in question. How is it, let 

 me ask, that the learned Doctor's word 

 has not become, ere this, current coin of 

 the realm ? Also that good word of his 

 used in this connection to denote the 

 reciprocal convertibility of endosarc and 

 cctosarc in the Amoeba, namely, ama;ba- 

 hnsis? S. LOCKW^OOD.

NOTICES OF BOOKS. 



The Opiutn Habit. By F. M. Hamlin, 

 M. D., Auburn, N.Y. Reprinted from 

 The Transactions of the Medical So- 

 ciety of the State of New York for 1885. 

 (Pamphlet, pp. 13.) 



In these few pages Dr. Hamlin describes 

 his experience with persons addicted to 

 the use of opium, and his method ot 

 treatment, which is rapid and effective. 



The Microscope in Botany. A Guide for 

 the Microscopical Investigation of Vege- 

 table Substances. From the German 

 of Dr. Julius Wilhelm Behrens. Trans- 

 lated and edited by Rev. A. B. Hervey, 

 . A. M., assisted by R. H. Ward, M. D., 

 F. R. M. S. Illustrated with thirteen 

 plates and one hundred and fifty-three 

 cuts. Boston: S. E. Cassino & Co. 

 1885. (Large 8vo, pp. 15 and 466.) 

 This is an elegant volume, which should 

 be in the library of every student of bot- 

 any and histology. The first two chapters 

 treat of the microscope and accessories, 

 adapted to the requirements of American 

 and English students by Dr. Ward. The 

 third chapter deals with the methods of 

 preparing microscopic objects, including 

 the cutting of sections, and mounting, in 

 various ways, examining living organisms, 

 and instructions for making drawings 

 from the microscope. The fourth and 

 fifth chapters nre probably the most valu- 



able, since the information contained in 

 them is not to be readily found elsewhere. 

 The former treats of reagents for micro- 

 chemical tests, the latter describes the 

 method of conducting such observations. 

 The methods for the complete microscopi- 

 cal investigation of vegetable structures 

 are here given in a manner that makes 

 the work invaluable to the student, who 

 is also relieved of the necessity of search- 

 ing through the very scattered literature 

 of this subject.

 Blakiston's) for 1886. Thirty-fifth year

This convenient pocket-book is so well 

 known to practicing physicians that no 

 commendation is needed in this place. 

 It is issued in excellent style, and contains 

 valuable tables that the physician should 

 never be without, as well as a most com- 

 plete system of recording particulars of 

 cases and visits.
