BRITISH PHARMACEUTICAL CONFERENCE. 
a list of them is in your hands. The Committee next drew up a list of subjects requi¬ 
ring investigation, and requested members to accept one or more and report thereon 
to the Annual Meeting. The result is that twenty-eight papers have been received 
—every one of considerable pharmaceutical interest; they will be read to you at the 
present and subsequent sittings of the Conference. In addition to the papers, a Re¬ 
port of the Sub-Committee appointed to consider the best means of preventing acci¬ 
dental poisoning will be brought before you.” 
Its adoption was moved by Mr. Jones, seconded by Mr. Bright, and carried. 
The Treasurer’s statement of accounts was presented and accepted.

Dr. Attfield introduced the Papers which had been sent in by reading one “ On 
the Extraction and Preservation of Aromata,” by Mr. C. R. Ticliborne, F.C.S.:— 
<e ON THE EXTRACTION AND PRESEEYATION OF AROMATA. BY C. R. C. TICH- 
BORNE, F.C.S., CHEMIST TO THE APOTHECARIES’ HALL OF IRELAND. 
[. Abstract .] 
11 Observing the preservative powers of glycerine for vegetable substances, the author 
packed different kinds of scented flowers in jars, and covered them with glycerine. In 
this way he had kept some for two years. If flowers, etc., so preserved be pressed, it 
is found that the glycerine has absorbed all the volatile oil, and when diluted and 
distilled furnishes a water in all cases superior to that from flowers preserved by salt. 
If the odoriferous glycerine be diluted and agitated with oils or fat, ointments, etc., of 
excellent quality are produced. In all these cases the glycerine is recovered by mere 
evaporation of w T ater from it. The delicate oils of orange, jasmine, heliotrope, etc., are 
best isolated by steeping the flowers in the glycerine, pressing, and again steeping more 
flowers, and so on ; finally diluting with water and shaking with chloroform, which 
removes the oil. The low boiling-point of the chloroform admits of its being separated 
from the oil by a temperature which does not injure the oil.” 
Mr. D. Hanbtjry remarked that the objects of the author were divisible into two 
classes, firstly, the preparation of distilled waters, and secondly, that of the more 
delicate volatile oils. He feared that the cost of pure glycerine and the difficulty of 
recovering it would prove serious obstacles to such a process. For the second purpose 
that had been named, a better method was required than the system of enjleurage , 
now in use in the south of Franee, etc. His friend Dr. De Ary, when travelling in 
Java, had extracted the delicate odoriferous principle of some species of jasmine, Pan - 
dora odoratissima, etc., and by the use of ether got minute quantities of butyraceous 
volatile oils. It would be an important desideratum if this method would answer 
in such cases, and he (Mr. H.) was satisfied that it well deserved more extended inves¬ 
tigation. 
Mr. Reynolds had found that the quantity of chloride of sodium in elder-flower 
water made from salted flowers was almost infinitesimal, and not to be determined 
quantitatively. The superior quality of water so made could not be doubted.
