Found by experiment that after frogs had been immersed for several hours in oil or water, or after they had been suffocated by ligature of the aortic bulb, their muscles had an acid reaction.--_Med. Centralb._, 1882, No. 50.

“The sub-maxillary gland of the dog was chosen for experiment, owing to its exposed condition, and the comparative ease with which its nerves can be isolated; a few experiments were made on the parotid, but these were not increased in number, since there seems little reason to doubt that that which is true for one salivary gland is also true for the rest.… In observing the flow of blood all the veins going to the jugular were tied, except the veins coming from the gland; then either the jugular was tied and cut across on the peripheral side of the ligature, and the blood allowed to run into a narrow test tube…; or a cut was made just at the division of the jugular, the jugular itself clamped, and the blood collected as before.… The pilocarpin was injected sometimes into the saphena vein, and sometimes through the facial artery direct into the gland, in the manner described by Heidenhain.… In every case the stimulus used was a Daniell’s Cell with a Du Bois Reymond’s induction apparatus.”--_Studies from the Physiol. Lab. Camb._, Part III. (1877), pp. 44, 45, 46.
