    The liftli and seventh experiments differ in their ivsults from the others, for in these the number of pulsations was only inereascd, and their maximum was induced in a short time. On the other hand, however, the third and sixth experiments are more striking, as a diminution of the pulsations took place, and did not gain their minimum in two hours more, besides being accompanied by those effects \\ hich attended the other experiments, viz. vertigo, nausea, See. ^vhich are generally reducers of arte- rial action. The gixjater permanency of the sedative or de- pressing effect of digitalis should mark its character among the articles of the Materia Medica. In all the experiments in which the pulse was first ele- vated and then depressed, notwithstanding the pulse gained its maximum of elevation in less time than it arrived at its minimum of depression, yet, the ratio of decrease was greater than the increase. If we take the first experiment it will be proved thus: The pulse was raised six strokes in 35 minutes, and then depressed eighteen in 85 mi- nutes. Thus, then, as 35 : 6 : : 85 : 14*57; that is to say, according to the ratio of the increasing pulsations, the diminished number ought to be 14*57, for the time given, instead of the real num- ber 18. The ratio will not be the same in the other ex- periments, but still it will exceed the ratio of in creasing pulsations. Here then, we llnd, that by a partial view of the .subject Dr. Moore has been led into an error, in
