The hark of the Indian tree Ail a n thus e:ccelsa. Roxb, 
has ])een chemically examined "by the author, v;ho states that 
it possesses medicinal virtues T!7hioh depend upon an 
azotized oitter principle of an fiC-; d natr're, which he 
names ailanthic acid. This suhntance he obtained as 
follows: .Exhaiist the "bark "by hoiling repeatedly '171 th 
ivater and concentrate the combin',^d aecoctions; Cool 
and add sufficient stror^g oxalic acid solution to pre- 
cipitate the lime, Add stroJig hasic lead acetr?,to solu- 
tion, v/hich precipitates f^mri, extractive matter, colouring 
natter, and excess oxalic acid raid filter, Conccntro.te 
the filtrate and when colu treat with hydrogen rolphide to 
precipitate the load, "boil, filter, and evaporate. The 
chenicrJ. properties of the arllanthic acid thus ohtained 
and of its lead and lino piJ-ts ijrc alscusscd. 
This tree possesses the characteristic medicinal 
and plv''siolof:iCQl properties of. the family ( Slm-aruhacaea) 
to^ v/hich it belong;:.. They resemhle so closely those of 
Ficraena excelsa , or Jamaica quassia tree, that the 
Indian plant may safely "bo considered a. substitute for 
it. These properties are discucsed at some length.

Rose bushes attacked by Aph i s rosae should be sprayed 
with quassia extract prepared, i rom chips of Q,uar~sia . amara , 
not of Picraena excel sa . When the bushes are badly infested, 
a vigorous syringing with water before spraying is very useful,
