in view the desirability of at least a gradual approach upon mutual 
concessions toward uniformity with similar preparations of other 
pharmacopoeias, particularly in the case of potent remedies which 
are in general use among civilized nations. 
6. GENERAL FORMULAE. 
It is recommended that general formulae be introduced, as far as 
the particular nature of the several drugs will permit, for fluid ex- 
tracts, tinctures, and such other preparations as are made by identical 
processes, and that the general formula to be followed in each case be 
merely indicated by reference. 
7. WEIGHTS AND MEASURES. 
The committee is instructed to retain the metric system of weights 
and measures as adopted in the seventh decennial revision. 
8. SUPPLEMENT. 
That the committee on revision be authorized to prepare a supple- 
ment to the pharmacopoeia at any time they may deem such action 
desirable. 
The delegates from the Ohio State Pharmaceutical Association 
offered the following suggestions : 
9. LIMITATIONS. 
It is recommended that every article in the United States Pharma- 
copoeia that has no medicinal value and is used solely for commercial 
or technical purposes be discarded from the next issue of the United 
States Pharmacopoeia. 
10. SYNONYMS. 
It is recommended that every common name and English title of 
articles used in the present United States Pharmacopoeia that is syn- 
onymous for both the medicinal and commercial drug be either dis- 
carded or modified so as to leave no doubt as to what is wanted. 
11. PRECEDENTS. 
In all matters not specially provided for in these “ general prin- 
ciples ” the rules established for previous revisions, if there are any, 
should be followed. 
Several additional resolutions are recorded as having been offered 
and discussed, but not adopted. 
12. MEDICINE DROPPER. 
At the fourth session Dr. Wm. H. Seaman offered the following: 
It is recommended that an official medicine dropper have its delivery end 3 
millimetres in external diameter, and adapted to deliver 20 drops of distilled 
water to a gramme at 15° C. 
This was referred without recommendation to the Committee on 
Revision.
