Xlviii PROCEEDINGS OE THE 



the business of his father, who had become paralyzed and incapable 

 of attending to it. 



In the autumn of 1837 he took the business at Clapham, having 

 been assisted by several friends, especially by the late Eichard 

 Hotham Pigeon, vs^hose large pecuniary aid was afforded in the 

 most liberal and trusting spirit. 



In 1841 on the establishment of the Pharmaceutical Society he 

 became one of its first Members, but took no active part in its 

 formation. In 1844i he was requested to become one of the Board 

 of Examiners. 



Mr. Deane was for nearly twenty years member of the Council, 

 and was President during a somewhat troubled and difficult period 

 in the existence of the Society. His services on the Pharmacopoeia 

 Committee will be remembered by those associated with him at 

 the time ; and although the College of Physicians, at whose insti- 

 gation the Committee was formed, had not the opportunity of utili- 

 zing the practical information obtained thereby, the labour was not 

 thrown away ; for many preparations of the British Pharmacopoeia 

 issued by the Medical Council bear traces of it. 



It should not be forgotten that Mr. Deane was the first President 

 of the British Pharmaceutical Conference ; and the fact of his 

 being chosen for that office is testimony of the high estimation in 

 which he was held by the leading pharmacists of the kingdom. 



In 1840 the Microscopical Society was formed, and he joined it 

 on its foundation. In 1845 he made the discovery of the existence 

 of Xantliidia and PolytJialamia in the grey chalk of Polkestone, a 

 bed below the common white chalk. 



The first Meeting of the new society which Mr. Deane attended 

 was at 338 Oxford Street, when he read a short paper on " Dis- 

 placement as a Method of preparing Tincture, &c. ; " and although 

 the value of the paper was not highly estimated by its author, he 

 nevertheless believed that it set many chemists to work in experi- 

 menting upon that method of preparing tinctures and extracts. 

 The process has since that time become more completely understood 

 and consequently more successful. His next contribution was a 

 paper entitled " Experiments on Senna," which was noticed by both 

 Dr. Pereira and Dr. Royle ; and he subsequently wrote (besides 

 many smaller ones) papers on opium preparations and extract of 

 ■meat, in which he was assisted by H. B. Brady, by whose ready 

 pen and pencil (Mr. Deane has observed) their interest was greatly 

 ausmentetl.
