The bark contains a volatile oil, fixed - wax, albumen, gum, 
sugar, starch, butyric acid, oxalic acid, an aromatic resin, iron- 
ming tannin, and an alkaloid miley the author names 
atherospermine. The lead compound of the tannin, obtained by 
precipitating the clear watery extract of the bark with acetate of 
lead, digesting the washed precipitate with acetic acid, and repre- 
cipitation with ammonia, added to exact neutralization, gave 
numbers agreeing with the formula C,H, 
After removal of the tannin and wéboteaieel éolable d in water and 
in dilute sulphuric acid, treatment of the bark with dilute soda 
extracts the aromatic resin, Saws can be precipitated by dilute 
hydrochloric acid, and purified by treatment with alcohol se 
water. The resin is brownish red, has an aromatic odour:
