mentation soon sets in, and should be promoted by main- 
taining the temperature between 70° and 80° F., during 
thirty-six hours. The supernatant fluid should then be 
decanted from the dregs of the malt, and the tar added 
gradually to these, in a small stream, stirring constantly, so 
as to distribute it uniformly among them and prevent its 
conglomerating in masses. The decanted fluid is then re- 
turned to the vessel, and the whole well stirred up from 
time to time for several days or a week, observing to add 
water occasionally to keep the original measure. The 
whole is then thrown on a piece of canton flannel, or other 
close strainer, the fluid allowed to pass, and the dregs ex- 
pressed strongly, to remove as much as possible of the fluid 
enclosed. The expressed liquid is then filtered for use: 
there is an advantage in allowing it to stand, until it gets 
nearly clear by subsidence, before filtering it. 
When first made, before filtering, wine of tar has but 
little color, but soon acquires a reddish-brown hue by ex- 
posure. It smells and tastes strongly of tar, is slightly acid, 
is not unpleasant to most persons, and when prepared as 
above, is undoubtedly a valuable auxiliary to the physician 
in pulmonary diseases. 
Solution of Citrate of Magnesia. — As this preparation 
has found favor with physicians and the public, and as it 
is of some importance to be able to prepare it speedily and 
without much complication, the following recipe is offered 
as more practicable than that noticed at Vol. XX, p. 254 of 
this Journal. The formula is for six bottles, and by mul- 
tiplying the quantities, any desirable amount may be pre- 
pared ; but as the solution has a strong tendency to deposit 
basic citrate of magnesia, the number mentioned will be 
sufficient for most retail establishments at one time. 
First prepare six twelve ounce bottles, and fit to them 
corks of the best quality.
