Diz MIKROSKOPISCHE ANALYSE DER DROGENPULVER.+- 
Microscopical Analysis of Powdered Drugs—An atlas 
for Apothecaries, Druggists and Students of Pharmacy, 
by Dr. Ludwig Koch, professor of botany at the Univer- 
sity of Heidelberg. First volume, First number. Pub- 
lished by the Brothers Borntraeger, Berlin, 1900. Price 
3 marks 50 pfennig (85 cts.), post free. 
The contents of this first volume embrace the Cortices 
and Ligna (barks, peelings and woods) of the German 
Pharmacopeeia, the present issue being devoted to Cor- 
tex Aurantii Fructus, Cortex Cascarilla, and Cortex 
Chine Succifubra—these being preceded by a general 
and special introduction, in which the methods of inves- 
tigation, including preparation of the sample, the media, 
reagents, etc., are fully set forth, us well as the special 
microscopical methods of research. There is also a special 
introductory dissertation on the Cortices of the Pharma- 
copoia, their anatomical structure, etc. 
The work will appear in parts, from time to time, but 
without fixed periods of issue, until completion, each part 
costing 3 marks and 50 pfennigs, or say 85 cents of our 
money. The exact number of issues has not yet been an- 
nounced. Every apothecary interested in the micro- 
scope, and every student of pharmaceutical microscopy 
should have this work. Nothing like it has ever been is- 
sued in any language, and that it is in German, should 
make but little difference, in this region, at least, where 
a general knowledge of German is almost universal among 
the educated classes. The plates alone are worth the 
money asked for the book.
