The air fe.emed to have fuffered little diminution either in quantity or quality : the reafon will appear from a fubfequent experiment. On cutting the wind-pipe of A, to blow up the lungs, a good deal of vifcid mucus flowed out. This was occafioried by flrong a£tion continued for fome time,. and was not feen in anything like the lame degree in B.

Upon comparing the experiments made upon blood out of the body, I was formerly uncertain what might be expe&ed to be the efR £t of hyper-oxygenation of the fyftem upon the colour and other qualities of the venous blood. (See' my obfervations on confump- tion.) Many fubftanees, containing oxygene, brighten venous blood, but oxygenated marine acid, according to feveral foreign chemifts of reputation, has an oppo- site effeft. Mr. Guillemarde and myfelf often noticed the dark appearance of the veins in animals charged with oxygene, and of the bloody they difcharged when wounded.

Both were killed, by blows on the back of the head, and opened nearly at the fame time. This ex- periment
