carbonate of ammonia which rises in the form of vapour, 
and becomes condensed within the recipient, whence we ex- 
tract it, as soon as the operation is at an end, and preserve 
it by introducing it immediately into glass tubes, hermetically 
sealed. 
At other times, we prepare a sort of oily carbonate of am- 
monia by the distillation of stag’s horns over the naked fire, 
and collecting the liquid product of the operation. From 
this it has been called spirit of hartshorn, a name we give it 
in the pharmacy. Ammoniacal salt thus obtained always 
contains pyrogenic oil (animal oil of Tippel), which modifies 
its properties. It is a medicine generally in our days aban- 
doned. 
As to that here mentioned, its modus operandi is that o 
liquid ammonia, than which, however, it is less active. 
Spoken of as being mollifying and depurative, carbon&te of 
ammonia has been employed under this title against glanders 
and farcy. It was imagined that by giving fresh organic 
activity, it might favour the resolution of certain organic 
enlargements, though nothing has shown that it possesses 
any special influence on the absorbent system. Lauded like- 
wise in certain epizootic diseases characterised by great pros- 
tration of strength, we have had to speak well of its employ- 
ment. 
However that may be, whenever it has been proposed to 
administer it to animals, they have had it given them mixed 
with honey or the extract of juniper, or in solutoin in bitter 
infusions. The dose for a horse varies from 8 to 32 grains 
(from 2 to 8 drachms), and for the ox between 16 and 48 grains 
(from 1 to 12 drachms). 
Here, we will bring our inquiry to an end. We have 
seen the classification of our author ; we have given speci- 
mens of his pharmacological detail under each of his grand 
divisions, all which will speak for itself. In our next, we 
shall take the work of Delafond and Lassaigne in hand, and 
examine it after the same manner.
