magazine devoted to Ophthalmology. Price S2.00 — same size

 Practical Methods in Microscojjy. By Charles H. Clark. Boston, 

 D. C. Heath & Co., 1894. 12° pp. 233. 41 cuts, 17 plates. 

 Believing that none of the existing volumes on the micro- 

 scope were sufficiently concise and explicit for the beginner, and 

 for those who have no teacher, the author has undertaken to 

 briefly present all that a beginner needs to know in order to use 

 the microscope success full}'. Gage's book is for the student 

 under guidance of a teacher; Clark's, for the solitary student. 

 He certainly has touched upon a great number of things of ele- 

 mentar}^ importance and has made very plain what others 

 sometimes leave unexplained assuming that their readers 

 " know something." The apparatus of Messrs. Bausch & Lomb 

 is quite fully pictured and described, and this makes the book 

 of more value in America than that of Cross & Cole, who de- 

 scribe English apparatus only. Bacteria, photomicrograph}', 

 polarization, and other collateral topics are briefly sunjmarized. 



Kindnes.U.o Animals. A. S. P. C. A. New York, 1S93, 24° 



53pp. 



This little catechism of 398 questions and answers i.s, we are 

 astonished to find quite sensible- Nearl}' everything said and 

 done by societies for jirevention of cruelty smacks of crankism, 

 silliness and folly, but this book, though containing a few fool- 

 ish things, is prett}'^ good. The fact that the English sparrow is 

 an intolerable pest is ignored and children are encouraged to 

 throw crumbs to it. Boj'S are warned that "it is cruel to catch 

 fish not good for food" (i. e. good for oil, guano, etc ) but we 

 ask is not the cruelty the same in all cases ? 



An earnest eff'ort should be made to introduce such a book 

 into Sunday School classes.

To the microscopist the book is of interest as explaining full}' 

 what is to be seen in plant life by means of the microscope 

 though the author alludes to the microscope only incidentally.
