    not so far depend on the observations of those who have gone before us as to admit further inquiry. The author, therefore, will submit to the reader's judgment an account of some experiments which he has himself made, and the deductions to which, in his opinion, they lead. As many of them were similar in their results, those which have a near resemblance shall be arranged under distinct •classes ; and one of the most satisfactory experi- ments of each class shall be fully related, so as to give a precise idea of its nature and effects. The remainder shall be exhibited in a short tabular form. This arrangement will comprehend four classes. 1. Slight Contraction.—By tbis the fact is ex- pressed, that a part of the vessel, in length not more than the thickness of a thread, became much smaller than the part above or below, and remain- ed in that state sometimes for a minute, sometimes for nearly half an hour. The femoral artery of a cat was exposed, and scraped with a scalpel. During the first twenty minutes no visible effect was produced ; but after that time, the contractions and dilatations were clearly perceptible, and in half an hour a slight permanent contraction occurred, which continued until the experiment was closed. 4
