more-powerful. Two grains are sufficient to destroy a large dog. M. Ma- 
gendie saw vomiting produced by one-sixteenth of a grain, in a man aged 
eighty-five : in whom, however, vomiting was readily excited. 
M. Magendie recommends the following formula for the exhibitions of 
pure emetine :— 
EMETIC DRAUGHT OF PURE EMETINE. 
Take of Infusion of Lime Flowers . . . 3 ounces 
Pure Emetine, dissolved in a suffi- 
cient quantity ofnitricacid . . 1 grain 
Syrup of Marshmallows ... . 1 ounce.—Mix. 
Dose—a dessert-spoonfal every quarter of an hour, until vomiting be 
produced. 
The following syrup is also a convenient mode of exhibiting emetine. 
, SYRUP OF PURE EMETINE. 
Take of simplesyrup . . . .. +. - 1 pound 
Pure Emetine. . .. . . 4 grains.—Mix. 
Dose—one or two tea-spoonsful, according to circumstances. 
M. Lerminier, of the Hospital Za Charité, has frequently administered 
emetine in the form oflozenges ; and, from his observations, he is enabled to 
a sert that ten or twenty grains of the root of ipecacuanha are adequately 
represented by one or two grains of emetine, (impure or coloured) so far as 
regards intensity of action. The convenient and agreeable form under 
which emetine may be administered, gives it a preference over ipecacuanha 
in substance.*
