pansions, with a smaller one, apparently in process of formation, 
attached to it.

Note to Pa'per on the Action of Hydriodic Acid on 31andelic Acid, 
hy Dr A. C. Brown. Bead March 20, 1865.

Since this paper was printed I have prepared the aldehyd of 
alpha-toluic acid. I shall only mention here that it possesses in a 
very high degree the smell of honey, which was observed in the 
case of the alpha-toluic acid described in the paper; and that it is 
probable that that acid contained traces of the aldehyd to which it 
owed not only its smell, but also the excess of carbon and hydrogen 
indicated by the analyses.
