298 On Cutaneous Absorption* 



Urine drawn immediately before entering the bath 

 was pale, and yielded no colour when treated with the 

 potash. Urine drawn three hours after entering the 

 bath was pale. Urine discharged one hour after leav- 

 ing the bath had considerable colour : and, with the 

 potash, yielded the bright- red. In three hours from 

 the time of leaving the bath, I again examined the 

 urine : it had more colour than the last portion, and 

 rendered a deeper red with the alkali. The urine dis- 

 charged the following morning had a faint tinge of red, 

 and was visibly affected by the alkali. 



Blood was drawn from my arm two hours before I 

 went into the bath, and again one hour and a half after I 

 came out of it. The two portions of serum had consi- 

 derable colour, though the last drawn portion was deep- 

 er than the first : neither of them were sensibly altered 

 bv the addition of the tests.

EXPERIMENT XIV. 



My friend Mr. Clark politely offered to assist me in 

 making an experiment. April 7, he entered the mad- 

 der-bath, fifteen minutes before 1 o'clock, P. M., and 

 left it fifteen minutes after 4 o'clock, P. M. The tem- 

 perature of the atmosphere was 47°, that of the bath 

 G5°, during the first 45 minutes : the remainder of the 

 time it fluctuated from 85° to 95°. His pulse, on en- 

 tering the bath, was 50 in a minute. An hour after, it 

 was 83. At the end of two and a half hours, 72; and 

 at the time of his leaving the bath, it Mas at G7.
