Brown-Séquard at Paris to Boston, and was mustering strength to resume his great place. Calling one day on a friend in Somerset Street, I found a visitor in the parlour, a powerful man weighed down by physical disability, whom I recognised as the sufferer whose name at the moment was uppermost in millions of hearts.
Although he dined with friends the next day, and was present at a family festival that week, he spoke of a dimness of sight, and of feeling "strangely asleep." On the 6th he returned early from the Museum, complaining of great weariness, and from that time he never left his room. Attended in his illness by his friends, Dr. Brown-Sequard and Dr.
The experiments of M. Brown-Sequard throw so much light upon the question at issue that I will quote at some length from the summary given by Mr. Darwin in his Variation of Animals and Plants under Domestication. Mr. Darwin writes: Darwin, "the above several negative cases, we now possess conclusive evidence that the effects of operations are sometimes inherited. Dr.
If, therefore, after the bodies have been galvanized, the duration of rigidity is much shortened and putrefaction much accelerated, it is reasonable to ascribe the same effects when produced by lightning to the property which galvanism shares with lightning, and not to those which it does not. Now this Dr. Brown-Séquard found to be the fact.
Of course I will go, unless Brown-Sequard orders me positively to stay on terra firma. But even then, I should like to have a hand in arranging the party, as I feel there never was, and is not likely soon again to be, such an opportunity for promoting the cause of science generally, and that of natural history in particular.
Not less remarkable than these results are the facts, which I with others of my audience have had the opportunity of observing, as shown by M. Brown-Sequard, of the artificial production of epilepsy in animals by injuring the spinal cord, and the induction of the paroxysm by pinching a certain portion of the skin.
To be sure, the doctrine was only an inference, though well-founded, of which the direct experimental proof was not to be obtained until the researches of Bayliss and Starling. Yet to Brown-Séquard belongs the immortal credit, if not of the originator, at any rate of the resurrector of the idea of using gland extracts to influence the body.
Brown-Sequard gives the following summary of his observations on guinea-pigs, and this summary is so important that I will quote the whole: "'1st. Appearance of epilepsy in animals born of parents having been rendered epileptic by an injury to the spinal cord. "'2nd. Appearance of epilepsy also in animals born of parents having been rendered epileptic by the section of the sciatic nerve. "'3rd.
Of this latter fact thirteen instances were carefully recorded, and a greater number were seen; yet Brown-Sequard speaks of such cases as one of the rarer forms of inheritance.
The Brown-Séquard conception inferred the existence of a postal system between cells, the blood supplying the highway for travel and transmission of the post, the post consisting of the chemical substances secreted by the glands.
