said to have been A in a minute. A
case is also related of healthy man of
81 whose pulse was seldom over 80 dur
ing the last two years of his life, and
sometimes not over &c. Another man
of 81 years of age enjoyed good health
and spirits with a pulse of 20, and there
| is also on record the curious instance
of a man whose pulse in health was
| never more than 10, and, to be consis-
tent in his inconsistency, when he had
fever his pulse fell to 40, instead of
rising, as is usual.
