In the same manner in which Dr. Brown-Séquard proved that paralyzed muscles have greater irritability, he also proved the correlative proposition respecting cadaveric rigidity and putrefaction.
Darwin's conclusion was that "the effects of injuries, especially when followed by disease, or perhaps exclusively when thus followed, are occasionally inherited." Let us now see what Professor Weismann has to say against this. He writes: "The only cases worthy of discussion are the well-known experiments upon guinea-pigs conducted by the French physiologist, Brown-Sequard.
Brown-Séquard establishes the law may be enumerated as follows: 1st. Paralyzed muscles have greater irritability than healthy muscles. Now, paralyzed muscles are later in assuming the cadaveric rigidity than healthy muscles, the rigidity lasts longer, and putrefaction sets in later, and proceeds more slowly.
Brown-Séquard, as the outstanding figure in the history of the glands of internal secretion, deserves some notice as a personality. In the words of the note-makers for novels and plays, he was a card. He was born in 1817 at Port-Louis, on the island of Mauritius, off Africa, then French property. His father was a Mr. Brown, an American sea captain; his mother a Mme. Séquard, a Frenchwoman.
According to the theory of Brown-Séquard, it produces an abatement of the nutritive functions through the suppression of an internal stimulus; and, although its relations to the imagination have not been especially studied, it is not rash to admit that it is an arresting cause.
Nay, it is only the other day that an eminent physiologist, Dr. Brown-Sequard, communicated to the Royal Society his discovery that epilepsy, artificially produced in guinea-pigs, by a means which he has discovered, is transmitted to their offspring.
Certainly the ether carries, untransformed, emanations, effluences, electricity, for instance, or the fluids of a magnet which sends to a distant subject an order to traverse all Paris to rejoin it. Science has no call to contest these phenomena. On the other hand, Dr. Brown-Sequard rejuvenates infirm old men and revitalizes the impotent with distillations from the parts of rabbits and cavies.
Brown-Sequard and made perfectly well; but he had temperament, climate, and everything that money might give, in his favor. A good many invalids have been helped by Brown-Sequard after other doctors had failed to help them. A sturdy New Hampshire farmer wounded his foot with an axe and was supposed to have split a nerve in it.
"It should be especially observed that Brown-Sequard has bred during thirty years many thousand guinea-pigs from animals which had not been operated upon, and not one of these manifested the epileptic tendency. Nor has he ever seen a guinea-pig born without toes, which was not the offspring of parents which had gnawed off their own toes owing to the sciatic nerve having been divided.
As a result, forty years elapsed before the implications of his studies were rediscovered by the Columbus of the modern approach to the internal secretions, the American Frenchman, Brown-Séquard.
