BRITISH AND UNITED STATES PHARMACOPOEIAS. 191 
Unguentum Zinci Oxydi would have been a better title. 
In the " compound tincture of ammonia," two ounces, in- 
stead of two drachms, of mastich are ordered. This error 
has been corrected by Mr. Phillips, in his authorized trans- 
lation of the London Pharmacopoeia. 
We have already mentioned that the Edinburgh Pharma- 
copoeia was revised in 1839, and that a second edition of the 
revised work appeared in 1841. On this second edition we 
propose to make some remarks. The work is not well edit- 
ed, and many small details, trifling individually, but import- 
ant in the aggregate, have been but imperfectly attended to. 
The typography is not executed according to a consistent 
plan. The general plan is to print genitives with ae, in- 
stead of the diphthong ae ; yet this rule is violated always in 
the Index, and frequently throughout the body of the work. 
In reciting the ingredients of preparations, the unit of weight 
or measure is expressed, indifferently, in two ways: as " a 
drachm," "one drachm;" "an ounce," "one ounce;" "a 
pint," "one pint," &c. Now neatness required the adoption 
of the first or second way exclusively, and good usage would 
have declared for the first. 
The following misprints occur in the work: — page 42, Te- 
rebintha Chia, for Terebinthina Chia ; page 56, Spiritus 
Dilutior, for Spiritus Tenuior; page 96, Jlntiraonii Tar- 
tarizatum, for Jintiinonium Tartarizatum ; page 98, 
Compound Tincture of Lavender, for Compound Spirit 
of Lavender \ page 178, Tincturae Senna Composita, for 
Tinctura Sennae Composita; page 195, Aqua Potassas Ef~ 
fervescens and Aqua Sodas Effervescens, for Potassae Aqua 
Effervescens and Sodae Jiqua Effervescens; page 196, Citrus 
Medicaz Fruclus* for Citri Medicas Fructus, — Convolvulus 
Scammonii Gummi-resina, for Convolvuli Scammonim 
Gummi-Resina, — Decoctum Althaese, for Decoctum Al- 
thaeas Officinalis,— Decoctum Hordeij Comp., for Decoctum 
♦This is given in the column of old names; but lemons were not offici- 
nal in the last Ed. Pharmacopoeia.
