and twigs of Uncar ia gambir (fain. Rubiacese.). Both drugs contain 
a large percentage of tannic acid and its compounds. Gambir was 
introduced on account of the difficulty of obtaining in the market true 
Acacia catechu. The Tinctura Catechu Composita and the Trochisci 
Catechu (U. S. P., 1890) are replaced by Tinctura Gambir Composita 
and Trochisci Gambir.

GELATINUM. 
Gelatin. 
Official in the British Pharmacopoeia under the same name; in the 
German as Gelatina alba. The U. S. Pharmacopoeia demands that 
upon ignition it leave not more than 2 per cent of ash. Most of the 
gelatin on the market has an acid reaction. 
GELATINUM GLTCERINATUM. 
Glycer ilia ted Gelatin. 
A mixture of equal parts of gelatin and glycerin. The mass when 
cold is solid, but easily melts on applying gentle heat. 
Basis for suppositories and bougies. 
Of late years both ointments and cerates have been largely super- 
seded. especially in Europe, by dermatologic pastes and glvcero- 
gelatins. The former are mixtures of the medicinal agents with 
starch, dextrin, or kaolin, and glycerin, soft soap, petrolatum, or 
lard, and are intended chiefly for antiseptic, astringent, or germicidal 
effects. The glycero-gelatins are firmer than the pastes, and must be 
melted before they can be applied. 
GLANDULE SUPRARENALES SICCT. 
Desiccated Suprarenal Glands. 
The cleaned, dried, and powdered suprarenal glands of the sheep or 
ox, freed from fat. 
Properties. — A light, yellowish, amorphous powder, having a slight 
characteristic odor; partially soluble in water. One part of the dried 
glands represents approximately 6 parts of fresh glands.

should, therefore, be freshly prepared. 
Dose. — 4 ‘Average dose: 0.250 Gm.=250 milligrammes (4 grains)."

The blood-pressure raising constituent of the suprarenal glands is 
upon the market under the names adnephrin , adrenaline , epinephrine , 
epirenan , hemisine , paranepjhrin , suprarenalin , suprarenin , etc.
