MISCELLANY.

have given quinine in all its forms ; but in certain cases, seeing that 
sulphate of quinine did not answer my purpose, I associated this salt 
with carbonic aoid, in order to combat with greater advantage, the ef- 
fects of the marshy infection which are complicated by a spasmodic 
state of the stomach; in this view, I make a mixture of tartaric acid, 
sulphate of quinine, bicarbonate of soda and sugar. I have administered 
this aerated febrifuge powder, while effervescing, in the interval be- 
tween the fits, after having dissolved it in half a glass of water: the 
patients take it without repugnance, and the fits ordinarily disappear 
after two or three doses. 
1 have observed that sulphate of quinine, rendered soluble by sul- 
phuric, tartaric, or citric acid, acts with great energy, even in a smaller 
dose, than ordinary sulphate of quinine. 
The following are the directions. for preparing the powder: — 
Tartaric acid 9 grammes. 
Sulphate of quinine 10 centigr. 
Triturate well and add to the mixture- 
Bicarbonate of soda 1 gr. 20 centigr. 
Powdered sugar 2 grammes. 
For one dose to be taken in half a glass of water, at the moment of 
effervescence, or else the two mixtures may be separately dissolved in 
30 grammes of water, and the solutions mixed and drunk at the moment 
of effervescence. 
The following is the composition of this gaseous febrifuge: — 
Sulphate of quinine 10 centigr. 
Tartaric acid 4 grammes. 
Bicarbonate of soda 5 " 
Powdered sugar 30 " 
Water 1 litre. 
Care must be taken first to introduce the sugar into the bottle, then 
the quinine dissolved in tartaric acid, and immediately afterwards the 
bicarbonate ; the bottle must immediately be hermetically sealed to pre- 
vent the escape of gas. It may be taken in the dose of half a glassful 
or a glassful every two hours. Ibid. 
The Metal Didym. — The seventh number of Poggendorff's Journal, 
contains a notice of the metal which Professor Mosander has recently 
discovered united with oxide of cerium, in which body he had pre-
