twenty-four hours a precipitate fell, giving the general characters of para- 
pectin. The supernatant liquid on evaporation left a scaly residue, astrin- 
gent to the taste, and perfectly soluble in water. Its aqueous solution 
reduced Fehliug and gave a copious bluish black precipitate with ferric 
choloride. Lime-water produced a bright golden-yellow colour, followed by 
a reddish-brown precipitate. From the tannins proper it differed in that it 
was not precipitated by solution of gelatiue. 
(ii.) This residue apparently consisted of pectin intermixed with small 
portions of No. iii. 
(iii.) This was a dark uncrystallizable treace-looking residue, which impar- 
ted to the palate a feeble sensation of sweetness. It was very soluble in 
water and reduced Fehling's solution abundantly. A strong aqueous solution 
was precipitated by absolute alcohol. 
D. The marc from the alcoholic extraction was finally percolated to 
exhaustion with cold water. The liquor was evaporated down and the extract 
obtained taken up with hot water. A considerable amount of albuminous 
matter, which remained insoluble, was removed by filtration. The filtrate 
was treated successively with neutral and subacetate of lead and the pre- 
cipitates decomposed in the same manner as described under C. The three 
liquids obtained, i., ii., iii., were evaporated down. 
(i.) This residue was the smallest of the three. After standing for a 
considerable time some crystals were deposited, which on examination proved 
to be citric acid. 
(ii.) Nothing of a crystalline nature was found in this residue. It appeared 
to consist chiefly of extractive matter. 
(iii.) ThiB residue after treatment with alcohol had the same characters 
and possessed the same properties as C. iii. It was not further examined. 
The result of our examination of this bark may be summarized by stating 
the different principles which we have found— (1) crystalline fat ; (2) wax; 
(51) acrid principle ; (4) oroxylin ; (5) chlorophyll ; (6) pectinous substances ; 
(7) F jhling-reduoing principle ; (8) astringent principle ; (9) citric acid ; (10) 
extractive matter.— Pham. Journ. Sept. 27, 1890.
