water to extract everything soluble, is pressed and cut into small 
pieces. To every five hundred parts of it in this state twelve 
of bicarbonate of potash are added, and the whole boiled in a 
sufficient quantity of water till solution takes place : evaporated 
on the water-bath it leaves a mass which may be drawn into 
strings or sheets, and dried like glue. In this state it may be 
preserved for any length of time, is soluble in water, and with 
sugar &c. forms an agreeable article of diet. 
Bubidin. —Morin* has extracted from cow-dung a substance 
to which he has given the name of Bubulin, and which he con¬ 
siders to be the ingredient to which the utility of cow-dung as 
a mordant is owing. It is obtained by taking up the soluble 
parts with water, evaporating to dryness, treating the extract- 
like matter with sether and alcholol, after which water dissolves 
the bubulin. It is precipitated by alum, by acetate of lead, and 
by sulphates of copper and iron. The soluble matter in dry 
cow-dung amounts to about 20 per cent., of which the bubulin 
constitutes upwards of one fourth. Berzelius considers this 
substance not peculiar to the dung of graminivorous animals. 
Odorhi , Animin , $c. —Unverdorben, to whose researches upon 
resinous bodies we have already referred, has discovered no less 
than four substances possessed of basic properties in animal 
(Dippals) oil. The first Odorin, is obtained by distilling the 
rectified oil previously neutralized by a little muriatic acid, and 
changing the receiver as soon as what comes over ceases to be 
entirely soluble in water. It is a colourless, oily, powerfully re¬ 
fracting body, soluble in water, and restoring the colour of red¬ 
dened litmus-paper. Animin is procured by continuing the di¬ 
stillation till only one twentieth part of the oil remains in the re¬ 
tort. The oily matter in the receiver is a mixture of odorin and 
animin : water dissolves out the former, and leaves the greater 
part of the latter. It is also in the form of an oil soluble in 20 
times its weight of water, and acting like odorin on litmus-paper. 
Olanin (ole um, aniu iale,) constitutes the greater part of what 
remains in the retort: if this residue be treated with 20 times 
its weight of water, the animin it contains is taken up, and a 
thick oily fluid remains, which is olanin. It acts also upon red¬ 
dened litmus-paper, and when exposed to the air gradually be¬ 
comes brown, and is changed into a substance which Unverdor¬ 
ben calls fuscin. 
Ammolin .—Ammolin is obtained only from the unrectified oil: 
the oil is digested for several hours with dilute sulphuric acid, 
decanted from the acid solution, washed with water, and the 
washings added to the solution. The acid has taken up the three
