    I sxaxy commence thie series with a few preliminary remarks, which will render more intelligible the subjects hereafter to be discussed. The natural temperature of the blood; circu- lating in the body, is 98 degrees of Fahrenheit’s thermometer ; the pulsations of the heart in a state of health from 60 to 84 degrees in a minute, the medium is 72, which may be con- sidered the natural standard. The pulsations, with respect to respiration, may be considered nearly as 4 to 1, or rather 7 pul- sations of the heart to 2 respirations in the adult: im children the pulse is much more frequent, in old age less so; and the smaller in proportion the animal is, the more frequent is the circulation: in children the pulse is very quick*. In the brute creation, as for instance, the horse, we cannot distinguish above 32 or 37 in a minute; in the dog 180. The pulse becomes ‘much accelerated in fevers, from 72 it has risen to 120, 130, 150 and even 160 in‘a minute, even so quick that it could not be ascertained, and beyond 200 it would be impossible to count it; * According to Heberden and Blumenbach, in infants at birth, the pulse 1s 140; first year 124 ; second 110; third and fourth 96; seventh 86; at puberty 80; manhood, or 21 years old 75; sixty years of age 60. | B
