ON ATROPINE. 
ART. XXVII.— ON ATROPINE. 
By Drs. Bouchardat and Stuart Cooper. 
The authors recommended the substitution of atropine 
for belladona, in order to obviate the uncertainty of the 
operation of the latter. The dose can be increased from 
two milligrammes to one centigramme [about T §^ths t0 
T Vo-ths of a grain troy.] 
The local pain caused by atropine when endermically ap- 
plied is only of short duration, and is not accompanied by 
any bad consequences. Internally, atropine may be given 
in the following forms : — 
1. Tinctura atropini. — 1 gramme of atropine dissolved 
in 100 grammes of spirit of wine of 85 per cent. ; one 
drop of this solution contains about half a milligramme of 
atropine. The dose is ten drops. 
2. Syntpus atropini. — One decigramme of atropine dis- 
solved in ten grammes of water, acidulated with one drop 
of muriatic acid, and mixed with 100 grammes of simple * 
syrup. In 100 grammes of this syrup is contained one 
centigramme of atropine. The dose is twenty grammes. 
3. Pulvis atropini. — One centigramme of atropine mixed 
with two grammes of sugar, and divided into twenty equal 
parts. Each powder contains half a milligramme of atro- 
pine. Children of five years old may take it in hooping- 
cough two or three such powders daily. 
4. Pilulse atropini. — Five centigrammes of atropine, 
mixed with pulv. rad. althseae and a small quantity of 
honey, may be made into fifty pills, and one or two given 
for a dose. 
5. Collyrium atropini. — One decigramme of atropine 
dissolved in 100 grammes of distilled water. Collyrium 
atropini fortius is prepared with five centigrammes of 
atropine and twenty grammes of distilled water. For dilat-
