when applied to the arm in a fresh state it causes irritation and 

 raises pustules. Major Megaw, I.M.S. has found a watery- extract 

 of 0-63 grams and an alcohohc extract of 0-2 grams by injection 

 sufficient to kill a guinea pig in 5 days and 4 hours respectively, 

 proving that tlie fresh bark contains a poison of distinctly 

 virulent type (Ann. Rep. Bd. Sci. Advice India, 1911-1912, p. 20). 

 Major Windsor, I.M.S. finds that the Arrow poison of the Arbors 

 is a paste made by pounding the soft parts of the plant and is 

 not obtained from the seeds (Chem. & Druggist, Feb. 10th, 1912, 

 p. 212; Indian Med. Gaz. Jan. 1912). 



The plant grows freely at Old Calabar and other parts of the 

 West Coast and in Tropical Africa generally under cultivation ; 

 but as wdth Bixa Orellana [see p. 57) the market for the seeds 

 could readily be overstocked.
