    the intercoflal mufcles of the oxygenated rabbit. They continued longer too in this. But confidering the * force and frequency of the contra&ions, the quantity of a&ion would have been greater in the oxygenated, had the irritability continued five times as long in the Other. Thefe phaenomena made me wifh for an opportu- nity of oxygenating animals of large fize, as horfes, and of drawing blood from their veins and arteries both before and afterwards. Such a train of experi- ments would form a very interefting fupplementto Mr. Hunter's refearches concerning the general principles of the blood. (See his Treatife on the blood, inflamma- tion, and gun-Jhot zuoands, p. 11—too.) The fpee- dier coagulation of the oxygenated venous blood I think remarkable, and as it happened in three experi- ments, it probably was not accidental. The more vi- gorous aftion of the oxygenated mufcles too deferves to be compared by a courfe of experiments with the tendency of oxygenated blood to coagulate fooner. Several perfons, of whom all did not know the one rabbit from the other, found the boiled flefh of the oxy- genated, in both cafes, more ftringy, harder, and lefs juicy. The difference was moft fenfible in the young pair. The greater ftringinefs was apparent on both thefe occafions to the eye. We obferved that the rabbits drank repeatedly du- ring their confinement in oxygeneair. The latter had been watered a fhort time before; I could not learn whether the former had or not. Perhaps this thirft (if fuch it was) depends on the excitement produced,
