oughly with one-sixth part of it, and the rest of the alcohol added. After stirring 2 
the whole well, and pouring it into a well-stoppered bottle, it is allowed to stand 
eight days in a dark, cool place. The tincture is then separated by decanting, 
straining and filtering ; it has a deep orange-brown color by transmitted light; a 
strongly vinous odor; a mawkish taste; and an acid reaction. Pes 
CHEMICAL CONSTITUENTS.—Several analyses of the bark have been made, 
all of which agree with the latest one by Mr. F. H. Davis.* He determined the 
presence of fixed and volatile oil, resin, wax, sugar, tannin, gum, starch, and 
oxalic acid; but failed, as had the others, to detect the presence of alkaloids or 
glucosides. : 
PHYSIOLOGICAL ACTION.—Ailanthus causes nausea, vomiting, great relax- 
ation of the muscles, and death-like sickness, very similar to that produced by 
tobacco-smoking in beginners, According to M. Hetet, the purgative property 
resides in the resin, while the volatile oil gives rise to the prostrating and other 
ill effects produced in some persons by the emanations from the flowers. The 
characteristic symptoms produced by Ailanthus are: vertigo and dizziness, severe 
headache, purulent discharges from the mucous membranes of the nose and eyes, 
dilated pupils with photophobia, pale, sickly, bilious countenance, irritation of the 
throat, loss of appetite, tenderness in the stomach and abdomen, looseness of the 
bowels, suppressed urine, oppression of breathing, languor and lassitude.
