 add the sulphate of iron in the proportion of 3 \ grains to each 

 fluid ounce. 



The next formula respecting which I would offer a few words, 

 is that for Mucilago tragacanthce. This preparation is rarely Mucilago 

 wanted, and never, I believe, kept ready prepared. It is, more- Tragacanthse. 

 over, much too thick, and twenty-four hours is a longer time 

 than can generally be allowed for its preparation. If a mucilage 

 containing tragacanth only is required, which in the presence 

 of so convenient preparation as the compound powder is very 

 questionable, the following formula will be found to afford a 

 good result. 



MUCILAGO TKAGACANT1LE. 



R Gum. tragacanth. pulv. grs. 60. 

 Aq. dest. fluid ounces 10. 



To the water contained in a pint bottle add the tragacanth, 

 agitate briskly for a few minutes and again at intervals until 

 the gum be perfectly diffused, which will occur in about five 

 or six hours. 



SOME REMAKES ON THE NOMENCLATURE OF THE 

 PHARMACOPOEIA. 



" Pharmacorum nomina, ssepius licet absurda, sanete servavi, utpote 

 complurium seculorum auctoritate, ratione legibusque exempta." Linnaeus. 



SOME months ago, there was presented to the Pharmaceutical ises. 

 Society by Professor Redwood, a very interesting paper "On the p r ^ife^or 

 Construction of a Pharmacopoeia," 1 one of the objects of which Redwood, 

 was to invite suggestions for improvements in a proposed new 

 edition of that work. As almost every pharmacist must have 

 made in the course of his experience some useful observations 

 respecting one at least of the 600 drugs and preparations which 

 the pharmacopoeia specifies, it is to be hoped that Professor 

 Redwood's invitations may receive many replies. For one, I beg 

 permission to offer a few remarks on the nomenclature of
