PECULIARITIES OF THE SWEAT IN CERTAIN PARTS 321 



ever, when conditions operate to increase the quantity of sweat, the 

 quantity of urine is proportionally diminished. The skin is undoubtedly 

 an important organ of excretion, and it may eliminate excrementitious 

 matters of a character as yet unknown. In regard to the inorganic 

 constituents of the sweat, there is no great interest attached to any but 

 the sodium chloride, which exists in a proportion many times greater 

 than that of all the other inorganic salts combined. 



Peculiarities of the Sweat in Certain Parts. In the axilla, the 

 inguino-scrotal region in the male and the inguino-vulvar region in 

 the female, and between the toes, the sweat always has a peculiar 

 odor, more or less marked, which in some persons is excessively dis- 

 agreeable. Whenever the secretion has an odor of this kind its reaction 

 is distinctly alkaline ; and its peculiar characters are due to a mixture 

 of the secretion of the other follicles found in these situations. Some- 

 times the sweat about the nose has an alkaline reaction. In the axillary 

 region the secretion frequently has a yellowish color, which may stain 

 the clothing.
