ZOOLOGY AND BOTANY, MICROSCOPY, ETC.

known handbook, which is a distinct advance on the two earlier editions. 
His knowledge and experience fully entitle him to select the methods which 
he thinks should be recommended to the worker, and to bury in the cold 
shade of absenco from his book those that have been superseded or have 
not stood the test of work. It is difficult to select where so much is 
admirable, but we think the severest critic will be satisfied with the 
paragraph on methyl-green or those on carmine staining. The chapter 
on Hrematein and other organic stains must be studied by every micro- 
scopist. But it is not only he who makes microscopical preparations 
that should obtain this book, it has many useful hints for the dissector 
of animals or the preparer of parts or specimens for museums. 
The microscopist who is unacquainted with the German tongue — and 
we fear there are still one or two left in out-of-the-way villages — will be 
misled by the term “juice of fruits” in par. 358 ; retranslation into 
German shows, however, that liquor amnii is meant. The author informs 
us that there is an error in par. 151, where 1 per cent, salicylic acid 
should read 0 * 1 and 5 per cent, salicylate 0*5; those who use the book 
must note this correction.

the stage-aquarium described by him in ‘ Lotos,’ xiii. ( 1893). The 
apparatus there described consisted of an object-holder, 5 by 10 cm. in size,
