remarkable for the large amount of chlorine present. No 
manganese was detected. The juice of the fresh bark and 
leaves had an acid reaction. 
It appears to us highly probable that the stimulating effects 
of the fresh bark, when applied locally, are due to the presence 
of trimethylamine, a part of which no doubt exists in it ina 
free state, and the remainder as a salt, most likely as the 
chloride. The rapid and painless manner in which the dilute 
aqueous solution of trimethylamine produces redness of the 
skin, might perhaps be utilized, if the extremely offensive — 
odour of the drug were not a bar. Trimethylamine is stated 
to act in a similar manner to aqueous ammonia locally, but it 
appears to us that trimethylamine is more active. 
The fleshy portion of the dried fruit of 8. oleoides has a taste 
‘similar to that of grape currants, and contains a large amount 
of sugar, which reduces an alkaline copper solution on boiling. 
The seeds contain a white fat with a melting point of 39 to 
40° C (uncorr.). The alcoholic solution was neutral to litmus 
paper. We also isolated an alkaloid, soluble in ether and 
amylic alcohol, and giving very marked precipitates with 
alkaloidal reagents, but no special colour reactions. It also 
afforded marked precipitates with chromate and bichromate of 
potassium from its solution in H*So*. The taste was some- 
what bitter and harsh. We are not in a position to state 
whether this principle differs or not from the one we detected 
in the root bark. A yellow colouring principle is also present 
in the seeds, which gives a deep bright yellow coloration with 
alkalies.
