ON CARRAGEEN MOSS. 
ployment. Carrageen is a substance which, without con- 
tradiction, deserves the attention of practitioners, on ac- 
count of the abundance of its gelatinous, demulcent, and 
nutritious principle ; moreover, the formulae of M. Mou- 
chon appear so rational that we hasten to lay them before 
our readers. 
1. Gelatine of Carrageen. 
Carrageen was submitted to three successive decoctions 
to almost completely exhaust it of its gelatinous matter, 
then the decoctions were evaporated on sand-baths, in a 
glazed saucepan to the consistence of a thick syrnp, and the 
concentration was finished on the stove to almost perfect 
dryness, in moulds of white iron, covered with a thin layer 
of cacao butter, and furnished with gelatine, in such a 
manner as to form thin, transparent, and easily pulverised 
plates, especially by mixing the matter with sugar. 
One gramme (15£ grains) forms 180 grammes of water 
into a jelly, and constitutes with 90 grammes of water, and 
as much sugar, an equal quantity of a sufficiently consistent 
product. 
2, Saccharide of Carrageen. 
To obtain this product we have only to add to the gela- 
tinous liquid, concentrated to the consistence of a thick 
syrup, four times as much sugar as carrageen. The opera- 
tion is completed in a sand-bath, care being taken to stir 
the syrup often until every portion may easily be powdered.
