FOOTNOTES:
[1] The usages in English laboratories in relation to this experiment are in accord with Professor Richet's views.—(W. D. H.)
[2] It may not be known to many readers, that it is possible to keep alive for hours and even days the heart entirely removed from the body of a dead mammal. On such a heart the action of drugs can be admirably studied and demonstrated. I once had in my own laboratory a rabbit's heart that continued to beat for nearly five days after the remainder of the rabbit had served for the dinner of my laboratory attendant.—(W. D. H.)
[3] The word intoxication here and elsewhere is used in its literal sense, viz., poisoning. It is not limited, as in popular parlance, to the poisonous effects of alcohol.—(W. D. H.)
