THE PHARMACEUTICAL JOURNAL AND TRANSACTIONS. 
[January 25 , 187<f, 
side of the Atlantic, thus rendering comparisons not 
absolutely hopeless.) The drachm weight is heavier 
than the fluid drachm, for it contains 68‘2 minims; the 
scruple of 20 grains weight contains 21 minims, and 
one grain has the volume of 1 *0533 minims. On the 
other hand, the gallon of eight wine pints weighs a 
trifle over ten troy pounds, or 58,329 grains; the 
pint is rather more than one troy pound and 
a quarter or 7291 grains ; the fluid ounce is 
nearly *95 of j an ounce weight, or 455-6944 grain; 
the fluid drachm weighs not quite 57 grains; the 
weight-equivalent of 1 minim being 0-9493 grain. 
“It is highly important that persons engaged in pre¬ 
paring medicines should be provided with troy weights. 
But those who are not so provided can make their avoir¬ 
dupois weights available as substitutes for troy weights, 
by bearing in mind that 42-5 grains, added to the 
avoirdupois ounce, will make it equal to the troy ounce; 
and that 1240 grains, deducted from the avoirdupois 
pound, will reduce it to the troy pound.” 
Following, indeed heading, the lead of the British Phar¬ 
macopoeia the weights and measures of the metric decimal 
system, are set forth in appended tables, their relation to 
the weights of the U. S. Pharmacopoeia and the relation 
of the latter to the former being very fully given. 
Also the relation of measures of the U. S. Pharmacopoeia 
to cubic measure. 
The galenical nomenclature of this fifth edition of the- 
Pharmacopoeia has scarcely been altered. The term 
alcoholicum has been dismissed in all cases where there 
is but a single extract of a medicinal substance, and this, 
is specified by the term extraction, as “ extraction nucis- 
vomicae ’ instead of “ extraction nucis vomicae alcoholi — 
cam .” 
_ The chemical nomenclature has been altered con- 
siderably “to place the work in accord with the pro— 
gress of chemical science.” The particular variety of 
modem nomenclature adopted is that which, five vears-. 
ago, was strongly advocated for use in pharmacy, by the ■ 
writer of this notice, in a paper which had the support 
| of all the leading chemical, medical, and pharmaceutical 
authorities in this country. He may, perhaps, be par¬ 
doned for regarding with much satisfaction the very- 
practical support his advocacy has now received at the- 
hands of the compilers of the important Pharmacopoeia 
under review. It is unnecessary to recapitulate the- 
many advantages, of the system, its simplicity, or the- 
ease.with which it may be understood and employed 
but inasmuch, to use the words of the preface of the new 
U. S. P., “the modifications thus made will probably 
soon be the language of pharmacy,” it may be desirable- 
to give a list of the old and new names now first officially- 
sanctioned.
