for all apothecaries, druggists and students of pharmacy. 
By Dr. Ludwig Koch, Professor of Botany, at Heidelberg 
University. Appearing in parts—3d Fasiculus.. Leipzig 
and Berlin. - The Borntraeger Bros., 1901. 
The third fasciculus of, this suberb work, which com- 
pletes the first volume, is just at hand and is in every 
respect well worthy of those that have already appeared 
and of which we haye heretofore spoken at length. The 
present number finishes up the Barks and takes up and 
finishes the Elements of Wood Fibres, Wood Parenchy- 
mata,etec, Four plates (from X to XIV) and two tables. 
We desire to impress upon students of pharmaceutical 
microscopy the importance of this work. Nowhere else, © 
in all the literature of the profession, can the microscopi- 
eal structure of this most important part of the stock 
of every druggist, be found so plainly and excellently de- 
picted. In the text all the methods are of procedure are 
fully explained, so that with the book in hand the drug- 
gist is always in position to thoroughly test the purity 
of his powdered drug. 
The price of the volume just completed is 12 marks, 
and in accordance with the announcement made origi- 
nally, that of the second volume will be 15 marks. It is 
obtainable only on subscription, which may be made at a 
bookstore, or sent directly to the publishers at Berlin.
