FECULA OF SOLANEiE. 
229 
Our experiments were made with two kinds of green fecu- 
la; the first, which we shall term the insoluble matter, is the 
substance held in suspension in the juice after expression. — 
It may be separated by passing the juice through a linen 
cloth to remove any fragments of the plant, and afterwards 
filtering through paper; the residue is to be well washed with 
pure water. 
The second kind of green fecula, is the coagulum that 
forms when the juice after having been strained through a 
cloth, but not filtered, is subjected to the action of heat; it 
contains all the substances found in the first, and also albumen 
in a state of coagulation. This fecula was also purified by 
repeated washings before it was used. 
As these green feculas, and especially the last, acquire much 
density in drying, and hence would be difficult to administer, 
we took the precaution whilst they were still in a soft state, 
of triturating them with sugar, and drying the mixture in a 
stove, thus obtaining a finely divided powder. 
Insoluble green fecula of belladonna. This was admi- 
nistered to two patients; in the first, a woman of sixty years 
of age, affected with catarrh and chronic gastritis; we com- 
menced with one grain and augmented the dose in the same 
proportion every day; on the tenth day some effect appeared 
to be produced, the patient stating that she experienced slight 
vertigoes. The quantity was increased to fourteen grains 
without inducing any dilatation of the pupil, any headache 
or modification of the pulse, or even any derangement of the 
digestive functions. 
The second trial was made on a female of thirty-three 
years of age, convalescent from an attack of articular rheuma- 
tism. The dose of the fecula was increased to twenty grains 
without producing any appreciable effect. 
Green fecula of belladonna by coagulation. This was 
administered to a woman aged 20, affected with rheumatic 
pains. We commenced with two grains, augmenting the
