misprints in the names and references of the Index. 
The Latin nomenclature is, in many instances, inconsistent 
with itself. In support of this criticism, the following instances 
may be adduced: Spirit of Ammonia is Ammonias Spiritus in 
the Materia Medica, and Spiritus Ammoniae in the Prepara- 
tions. The following are similar discrepancies: — Aqua Ammo- 
nias and Aqua Ammoniae Fortior, (Materia Medica), Am- 
moniae Aqua and Ammoniae Aqua Fortior, (Preparations); 
Plumbi Diacetatis Aqua, (Mat. Med.), Plumbi Diacetatis 
Solutio, (Prep.); Aqua Ammonias Acetatis, (Mat. Med..) 
Ammoniae Acetatis Aqua, (Prep.); Aqua Potassae, (Mat. 
Med.), Potassae Aqua, (Prep.); Copaibae Oleum, (Mat.Med.), 
Oleum Copaibas, (Prep.) Almonds are expressed by the Latin 
singular Amygdala, and yet, in the Preparations, the Edinburgh 
College have given us the titles of Conserva Amygdalarum, 
and Mistura Amygdalarum, instead of Conserva Amyg- 
dalae, and Mistura Amygdalae. Again, Gallae is the Ed. 
officinal name for galls ; but the name is in one instance not 
consistently carried out ; for we have as a preparation, Un- 
guentum Gallae et Opii. In the case, however, of the tinc- 
ture, the name is consistently given, — Tinctura Galla- 
rum. The oil of cubebs is directed to be obtained according 
to a general formula, given under the head of " Volatile 
Oils." Its Latin officinal name, from the manner in which 
these oils are enumerated, is not distinctly indicated ; but as 
Cubebae is given as the name of cubebs, the oil should be call- 
ed, to be consistent, Oleum Cubebarum. This name, how- 
ever, is not recognised by Dr. Christison, who gives, in his
