Adelaide, 6th January, 1886. 
As most of your readers will doubtless be aware, there has been some little 
stir of late in this colony concerning pharmaceutical matters. Chiefly owing to 
the exertions of Mr. Main, of King William-street, a meeting was held in 
August last, at which most of the city and suburban chemists were present. 
It was convened for the purpose of considering the invitation of delegates to 
the Sydney Conference then pending, and also of discussing the desirability 
of founding a Pharmaceutical Society in this colony. After deciding that to 
send delegates would be premature, those present unanimously agreed to form 
the nucleus of the Pharmaceutical Society of South Australia, and a committee 
was appointed to frame rules for its conduct, etc. At subsequent meetings these 
rules were discussed and passed, after some alterations had been agreed to, and 
the election of officers for the present year took place, resulting in Mr. Harrison, 
of Rundle-street, being chosen as president; Mr. Grundy, Hindley-street, vice- 
president ; Mr. Poole, King William-street, hon. treasurer ; Mr. Main, King 
William-street, hon. secretary ; and Messrs. Grummet, Parker, and White for 
the remaining members of the committee. 
Of course, up to the present, little has been done except initiatory work, 
but as soon as this has been disposed of it is intended that subjects of 
pharmaceutical interest shall be considered, with a view to stimulating the study 
of such, especially among the younger members, while the trade interests of 
pharmacy are also not to be overlooked at the meetings of the society. At 
present these meetings are held in Jackman’s Rooms, but it is proposed that a 
private room be taken for this purpose, where also the society could place such 
specimens, books of reference, etc., as it is hoped will be accumulated for the 
use of its members. 
A noticeable feature in the earlier meetings was the unanimity of opinion as 
to the inadvisability of a Pharmacy Act. It was generally considered that at 
present such an Act would not benefit the chemists of the colony, and it was
