![[Reprinted from the Journal of the Chemical Society, December, 1SG5.] By Maxwell Simpson, M.D., F.R.S. In a paper which appeared some time ago in the “Transactions of the Royal Society,”* I showed that the cyanides of the diatomic radicals (at least those which form glycols) when treated with potash, yield bibasic acids which contain respectively four equiva- lents of carbon more than the parent radicals. Analogy would lead us to infer that the cyanides of the triatomic radicals would suffer a corresponding decomposition when treated with the same reagent, and yield tribasic acids, containing respectively six equi- valents of carbon more than the original radicals. Thus, as we obtain in this way from the cyanide of ethylene (to take a par- ticular case) a bibasic acid of the composition C8H608 (succinic acid), so from the tercyanide of allyl (CcH5Cy3), if the analogy holds good, we ought to get a tribasic acid, having the composition C12H80i2 : C4H4Cy2+ 2(^)0,) + 4HO = O. + 2NH:i C8H5Cya+3(g)o2) + 6110 ) 08 + 3NHS The following experiments were performed with the view of testing the correctness of the above inference :— * Philosophical Transactions for 1861, p. 61.](https://iiif.wellcomecollection.org/image/b22435153_0003.jp2/full/800%2C/0/default.jpg)
