194 BRITISH AND UNITED STATES PHARMACOPOEIAS. 
Sol. Jlrgenti Jlmmoniati (test), Sol. Barytae Nitratis 
(test), Sol. Sodae Phosphatis (test), Morphiae Muriatis 
Sol., Calcis Muriatis Sol., Cupri Jlrrimoniati Sol., Plumbi 
Diacetatis Sol. Using " Liquor," they have Liquor Jlrse- 
nicalis and Iodinei Liquor Compositus. Certainly, in a 
work intended as a standard of Pharmacy for Scotland, greater 
uniformity was to be expected. One mode of expression in 
these cases should have been selected, and uniformly em- 
ployed. As " Aqua" is now universally applied to the " distil- 
led waters," and as "Solutio" is not good Latin for "solution," 
the Edinburgh College would have acted wisely, if in their 
late revision they had followed the example of the London 
College, in invariably using the word "Liquor." 
In the titles of two preparations, dried alum and dried sul- 
phate of iron, " exsiccatum" is used to signify u dried;" in 
the title of a third, dried carbonate of soda, " siccatum" is 
employed. The nomenclature would have been neater, if 
"exsiccatum" had been employed here also. 
To express the vegetable medicines, the general principle, 
adopted successively by the U. S. and London Pharmaco- 
poeias, of using a single name where one part only of a plant, 
or one species of a genus is used medicinally, is usually 
acted upon by the Edinburgh College, but violated in a few 
instances. Thus we find in the Materia Medica list, Calamus 
aromaticus for Calamus; Cassiae cortex for Cassia; 
Cassiae pulpa for Cassia Fistula; Dauci radix for Ca- 
rol a; Glycyrrhizae radix for Glycyrrhiza; Gummi aca- 
ciae for Acacia; Quercus cortex for Quercus ; Rhamni 
baccae for Rhamnus; Rosae fructus for Rosa Canina; 
Salicis cortex for Salix. 
To the chemical nomenclature of the Edinburgh Pharma- 
copoeia many exceptions may be justly taken. For its de- 
fects a sort of apology is made in the Preface, consisting in 
the allegation that it is impossible to follow the nomenclature 
of the chemist, without too frequent and violent changes. 
Indeed the opinion is expressed, that a great error was com- 
mitted when chemical terms were first introduced into phar-
