    experience of Mr. Spalding in confirmation of this con- jeéture. It is not fo eafy to make the experiment upon animals, the efforts of fome under confinement being fo much more violent than of others. The laft experiment was made with a view to this queftion, but the two pre- - ceding incline me to refer {peedier death in this inftance to the violent ftruggles, rather than to the wine. Vil.—Another comparative experiment with an Animal charged with oxygene. Of two half-grown rabbits (K and L) of the fame brood, colour, fize, and apparent ftrength, K was put into a large refervoir containing atmofpheric air with a little oxygene. After fome hours it was taken out, and placed for an hour in a mixture of nearly equal parts of oxygene and atmofpheric air. It did not feemto fuffer in its refpiration ; K and L, which latter had remained at large inthe fame apartment, were then inclofed in a veffel, and placed in afreezing mixture. In 20 minutes fome of the cold brine was poured upon the bottom of the veffel in which the rabbits were: in 30 minutes L feemed affeéted, in 45 was fcarce alive, and in 55 was quite lifelefs, and frozen fiiff. K feemed fufhciently lively, only its feet were frozen ftiff, They were dip- ped in cold water, andthe animal recovered perfeétly. 1 obferved many convulfions and much tremor of the limbs during recovery. It was between 8 and g o’clock in the evening when the rabbits were taken out of the velfel. K, by 12, had recovered the ufe of its forelegs, and being left not far from a dying fire within the tender, was found in the morning running about the room, when it eat cabbage leaves freely. It was kept alive fora week, when the legs appeared difeafed from too quick application of heat at firft. The experiment being repeated without admitting ]i- quor into the receiver, the refult was fimilar, Would opium and wine enable an animal to refift the freezing mixture, as oxygene does ? Be VUL--
