Sugar.12 ounces. 
Dissolve the protosulphate of iron and 
carbonate of soda, each separately, in four 
fluid ounces of water, and mix the solutions. 
Wash the precipitated carbonate of iron with 
sweetened water, and drain on a muslin 
filter. 
Having placed the salts of lime, soda, and 
potassa in a suitable porcelain dish, add 
about two fluid ounces of water, and one 
fluid ounce of hypophosphorous acid; heat 
the mixture gently, and add the moist car¬ 
bonate of iron in small portions from time to

until the solution is complete. 
Add sufficient water to make the whole

The dose of this is a fluid drachm. 
Uniformity of Prices. —The chemists of 
Dumfries, guided by the example of their 
Edinburgh brethren, have unanimously 
adopted a uniform dispensing price-list and 
private mark.—June 17, 1869.

glycerine (so-called), see Yol. VIII. (n. s.)

J. F. T. (Kettering), wishes to know what 
quantity of Gingerine is yielded by ginger. 
P. P. (North Walsham).—‘Hooper’s Me¬ 
dical Dictionary ’ would probably answer the 
purpose—published by Longman and Co.

phite of lime may be made in the proportion 
of 3 grains of the salt to 1 ounce of simple 
syrup. Syrup of hypophosphite of soda, in 
the proportion of 5 grains of the salt to 1 
ounce of syrup. 
The Grievance of Apprentices. —Mr. T. 
H. Smith, Newport, Isle of Wight, in com¬ 
menting on the injustice done to apprentices 
by the new Pharmacy Act, is of opinion that 
all those who had been engaged in dispensing 
prior to the passing of the Act should, on 
obtaining a certificate of competency from a 
medical man and a chemist and druggist, be 
registered; and he hopes that petitions to 
this effect will be presented to the Society 
from every town. 
jET. J. P. —(1.) The chromic acid battery 
is constructed without porous cells. Plates 
of zinc and carbon are immersed in a mixture 
of bichromate of potash and oil of vitriol, 
sufficient of the latter being used to decom¬ 
pose the former. There is no evolution of 
gas, but the plates must be withdrawn from 
the solution when the battery is not in ac¬ 
tion. (2.) Oleate of soda may be made as 
described, but it is difficult to get it neutral. 
W. R. —There may be differences of opi¬ 
nion, as no doubt there are, as to the limits 
of the capability of Nessler’s Test for detect¬ 
ing ammonia. We should say about 1 in 
20,000,000. The preparation of the test is 
well described in Wanklyn’s book, which you 
appear to have.
