FIG. 38.
The chart M. M. (Fig. 38), as taken from Bourneville, represents the course of the temperature in a rapid case: each perpendicular line denotes an hour.
The difference in the temperature of the two sides has been variously stated, and probably depends on a number of factors besides the length of time that has elapsed since the first attack. There is probably, however, a tendency to excess of heat on the paralyzed side soon after the attack, owing to vaso-motor paralysis; and this difference will be more marked in the hands than in the axillæ. After a length of time which may be from days to months the temperature becomes equalized, or more frequently the relation is reversed, the paralyzed side being colder as atrophy takes place. Lepine19 gives a case where the axillary temperatures of the two sides continued the same within a small fraction of a degree for three days, and then separated very slowly, until at death the paralyzed side was six-tenths of a degree (Cent.) hotter than the other, in both being inferior to the rectal (107° Cent.).20

20 The chart in the original, and as reproduced by Bourneville, is wrongly lettered. The text says that the left side was the hotter.
FIG. 39.
The chart C. M. (Fig. 39) shows the excess of temperature in a case of meningeal hemorrhage. The dotted line is from the paralyzed side. The first observation was made two and a half hours after the attack.
