II. Notice of researches on the sulphocyanide and cyanate of naphtyl, conducted by Vincent Hall, Esq

The transformation of phenylcarbamide and phenylsulphocarbamide under the influence of anhydrous phosphoric acid, respectively into cyanate and sulphocyanide of phenyl, an account of which I submitted to the Society several months ago, suggested the probability that the hitherto unknown cyanates and sulphocyanides of radicals similar to phenyl might be obtained by analogous processes. To establish this point experimentally, Mr. Vincent Hall has examined, in my laboratory, the deportment of some of the derivatives ofnaphtylamine under the influence of agents capable of fixing ammonia and its analogues.
