PATENT FOR PURIFIED QUINOIDINE, ETC. 47 
I apply the designation Basic Extract of Bark, or I pre- 
pare this as follows: — To three pounds of the dry residue, 
as above, I add nine ounces by measure of concentrated 
sulphuric acid diluted with one gallon of water, and dissolve 
the same; and through this solution I pass sulphuretted hy- 
drogen, and proceed in the same manner as when produc- 
ing purified chinoidine, and in making solutions and saline 
compounds therefrom. 
Having thus described the nature of the invention and the 
manner in which the same is to be performed, I would 
have it understood that I do not confine myself to the details 
herein described so long as the peculiar character of either 
part of the invention be retained; but what I claim is, 
First, The manufacture of what I have called "Purified 
Chinoidine, " by purifying and reducing that matter to a state 
of powder, as herein described; and I also claim the making 
alcoholic and other solutions of such purified chinoidine, 
and also the producing saline compounds thereof. 
Secondly, I claim the manufacture of what I have called 
"Amorphous Quinine" by separating the matter soluble in 
ether from other matters, as herein described; I also claim 
the preparing alcoholic, ethereal, and other solutions there- 
of, and I also claim the preparation of saline compounds of 
the same. 
And, thirdly, I claim the manufacture of what I have 
called "The Basic Extract of Bark," by separating such 
product by ether from the soluble matter, and preparing such 
extract as herein described, and producing alcoholic and 
other solutions and saline compounds thereof. 
In witness whereof, I, the said John Lloyd Bullock, 
have hereunto set my hand and seal this twelfth day of 
November, in the year of our Lord one thousand eight 
hundred and forty-six.
