[78 BRITISH PHARMACEUTICAL CONFERENCE. 
portion, as the creasote is thrown down from it again on diluting it with the 
water. If the spirit of juniper has been ordered as a flavouring, and to cover 
the taste of the creasote, it is by no means the best that could have been 
chosen; it has the disadvantage of making the mixture milky at first, which, 
however, will become clearer on being allowed to stand for a day or two by 
the finely-precipitated oil of juniper coalescing and floating on the surface m 
the form of very small globules, besides which the mixture is rendered tar 
more likely to disagree with the patient in the class of affections for which 
creasote is generally administered. For these reasons I suggest the follow¬ 
ing form, as, I think, a decided improvement:— 
Creasote.16 minims. 
Syrup of Orange Flower .... 2 ounces. 
Distilled Water.14 ounces. 
Mix the creasote with the syrup, then gradually add the water, shaking 
the mixture after each addition. . 
I herewith lay before Conference for it to pronounce its verdict upon them 
the following specimens of mist, creasotiNo. 1, prepared according to 
the British Pharmacopoeia; No. 2, prepared without acetic acid, but other¬ 
wise according to the British Pharmacopoeia; No. 3, prepared according to 
the suggested formula. _ 
It will be seen that the suggested formula contains the same amount ot 
creasote as that of the British Pharmacopoeia, that is, one minim to the fluid 
ounce, and I should here state, that without measuring it two drops will be 
found as near as can be equal to one minim. The creasote I used m these 
mixtures was a very fine specimen, prepared by Messrs. Morson and Son, and 
was exhibited at the late International Exhibition, so that it must have been 
prepared some three years and a half ago, and although prepared so long it 
has undergone but very little change in colour. The foreign and much 
cheaper creasote, or impure carbolic acid, should on no account be used for 
internal administration ; it is of uncertain composition, usually obtained from 
coal-tar, and only about one-half the price of the creasote ordered in the 
Pharmacopoeia. . , 
In conclusion, I much regret that some member of Conference has not 
given us an able report on No. 115, or the creasote of commerce ; it is a sub¬ 
ject that requires a great deal of further investigation, as it is doubtful if any 
two samples of creasote are the same either in chemical composition oi me- 
dicinal effect, and I must candidly acknowledge that I know of no reliable 
test for distinguishing them. 
Wilton , near Salisbury , August 8, 1865. 
In the discussion upon this paper, a member stated that he had found magnesia to 
increase the proportion of creasote taken up. 
Mr. Reynolds said that in some experiments upon Calvert’s carbolic acid, he found 
one part of the acid to dissolve conveniently in three parts of glycerine. He thought 
this might be an eligible method of treating creasote for internal administration. 
Mr. Hqt.t,t er thought that more information was needful before we could feel satis¬ 
fied that the great difference in price between different samples of creasote was one that 
was warranted by any superiority in the higher-priced ones. 
Mr. Tuck, in acknowledging a vote of thanks, said any credit in the matter was due 
to the Conference itself, since it had caused him to devote himself to these labours.
