The author stated, that, being struck with the singular resemblance between the properties of creosote and those of carbolic acid, as described in all chemical works, he had tried the action of a mixture of chlorate of potash and hydrochloric acid on creosote, and had thus obtained a very large proportion of chloranile, the compound yielded by carbolic acid, when treated in the same way. He had also obtained, by the action of nitric acid on creosote, evidence of the production of nitropicric acid, which is also obtained from carbolic acid.
