BRITISH AND UNITED STATES PHARMACOPOEIAS. 201 
121, 123, and 124, and Mucilage of Gum-arabic in the In- 
dex; Pulvis ipecacuanhae compositus, Powder of Ipecacuan 
and Opium at p. 140, and Compound Ipecacuanha Powder 
in the Index; Syrupus simplex, Syrup at pp. 90, 123, and 156, 
and Simple syrup at p. 160. The minor discrepancies in 
English nomenclature are innumerable. It may be alleged, 
however, that these discrepancies were intended; various 
English names for the same thing having been given, either 
to identify the substances meant, or to render the Index more 
copious and useful. Now we have no objection to English 
synonymes in certain cases, printed in a subordinate type; 
but the framers of an English Pharmacopoeia should adopt a 
system of English names, which should be printed in a uni- 
form type, and which should always be adhered to, whenever 
it is intended to represent the same substance. The follow- 
ing extracts, printed as they appear in the Materia Medica 
list, show in what a slovenly manner it is drawn up.
