u moral turpitude” forgiven, in consequence of his having succeeded in playing 
first fiddle, and making our local secretary play a very indifferent second. 
As to their amendments, I do not see anything to quarrel with, except that in 
clause 4 I would suggest that registration and keeping the register must be 
attended with some little expense, and that as the United Society require a 
guinea for registration and annual payment of ten shillings and sixpence, the 
Pharmaceutical Society are not very grasping in requiring a similar fee but no 
annual payment. 
Clause 16 I need not remark upon. 
THE PROPOSED LEGISLATION AND THE BENEVOLENT EUND. 
TO THE EDITOR OF THE PHARMACEUTICAL JOURNAL. 
Sir,—I think the proposition of your correspondent “ O.” so good, and so 
likely, if agreed to, to produce most important results in reference to our com¬ 
ing Parliamentary campaign, that I cannot forbear asking you to insert this 
note calling attention to it, on the part of the principal parties concerned,—« 
the Council of the Pharmaceutical Society, and the chemists entitled to regis¬ 
tration under the proposed Bill. 
It is my opinion that our Society, being now tolerably well-off for funds, 
could very well afford to incur without assistance the cost of a new Pharmacy 
Bill. Let it, then, abstain from profiting by the registration fee, generously 
applying it to the much-needed increase of our common benevolent fund. 
I believe that by so doing a vast amount of the clamour against the “ ini¬ 
quitous tax” would be knocked on the head, whilst a permanent good would be 
effected to the present and future members of the Pharmaceutical body.

ON THE USE OF LITMUS TINCTURE FOR INDICATING THE 
POINT OF NEUTRALIZATION OF ACIDS AND ALKALIES 
BY GASLIGHT. 
TO THE EDITOR OF THE PHARMACEUTICAL JOURNAL. 
Sir,—When litmus tincture is used by gaslight for the purpose of determin¬ 
ing the point of neutralization of acids and alkalies in volumetrical analysis, it 
is difficult, if not impossible, to note the change with any degree of precision, in 
consequence of the blue colour of the litmus appearing mauve. This may be 
remedied by watching the change through a piece of green glass not too deep in 
colour. The faintest trace of blue is then readily discernible, owing to the green 
glass absorbing the red ray and transmitting the blue, while the change to red 
will show an olive tint. 
The glass best suited for the purpose is that used by opticians for green spec- 
taclas. It is advisable to select the glass by gaslight, using for the purpose a 
few drops of litmus tincture in a tube or phial filled with water.

TITE PRESERVATION OF LEECHES. 
TO THE EDITOR OF THE PHARMACEUTICAL JOURNAL. 
Sir,—The constant loss sustained by retail dealers in leeches, especially by 
living in small towns where the demand is uncertain, has been a subject of dis¬ 
cussion for many years. 2 M 2
