    CHAPTER III. THE PULSE. The pulse varies with the age of individuals; at birth it beats from 130 to 140 in a minute: mean rate for the first month, is 120; limits during the first year, are 106 to 120; for the second year, from 90 to 100, for the third, from SO to 90—nearly the same for the fourth, fifth, and sixth years; in the seventh year, pulse about 78; from the twelfth year, it differs but little from that of adult age, which is estimated at from 60 to 80, according to individual constitutions, &c. (Heberden.) The common standard of frequency may be placed at from 70 to 75 beats in a minute. (Falconer.) From the 45th to the 60th year, the pulse gradually becomes slower; after this period, it again rises in frequency. (Floyer.) Generally more frequent in women than in men. (Falconer.) Climate influ- ences pulse; more frequent in hot than in cold countries. The time of day: slower in the morn- ing than at other times; most frequent soon after dinner; slower during sleep than in the waking state. Bodily exercise accelerates the pulse; varies according to the position of the body; slowest while lying down; slower when sitting than when standing. (Dr. Robinson.) Mental excitement in- fluences the pulse; joy, and anger, render it fuller and more frequent; grief, sorrow, and fear, de- press it. Mode of examining the pulse. (Celsus, Rush.) Not to be examined immediately on entering the patient's room;—the examination to be repeated at short intervals; should be felt in both wrists, the arm having its muscles relaxed by proper positions; two or three fingers to be applied to
