this exception the skin there is quite smooth. In women, hair is 

 developed at that time on the pubis only, and that to a very limited 

 extent. It may occasionally be seen round the nipple of the breast, 

 and in the axilla. In after life, and in some rare instances at an earlier 

 period, there is a development of hair on the female lips and chin. 



Where the operation of castrating has been performed in man, the 

 hairy sexual marks are lost ; and where a corresponding occurrence has 

 been resorted to in a female, {i. e. the removal of the ovaries,) it is stated 

 that the development of hair resembles that of man's. There are some 

 cases on record of women as hairy as men, and yet perfect women in all 

 other respects. After a certain age there is a great tendency to the 

 atrophy of the hair ; this is shown by the bald scalp of old age, and the 

 grey hair of those who retain it — the grey colour being an indication of 

 deficient energy in the bulb. 



I do not know whether these changes take place in other parts besides 

 the head and face ; as far as I can charge my memory I have never seen 

 grey hairs upon the pubis — certainly I have never known them fall off 

 by age on any part except the head. 



Hairs are much influenced by disease ; it is well known they fre- 

 quently fall off after fevers. In this they partake the same characters 

 as the skin; it generally desquamates, they fall off; occasionally the 

 follicles are destroyed — usually, however, the hair is reproduced. This 

 'admits of exceptions : in erysipelas, exempli gratia, the whole of the 

 cuticle peels off, but the hairs are retained. 



Hail's are sometimes met with in out-of-the-way places. I have met 

 with them in the ovary ; others have found them in uterine moles, in 

 tumours, on noevi, in the intestines, gall-bladder, and on the conjunc- 

 tiva. In the nostril they are commonly met with in man, and on the 

 tragus of the ear. This is rare in the opposite sex. 



The only part of the sldn free from hairs, are the palms of the hands 

 and feet, the tips of and the interstices between the fingers and toes, 

 and the great body of the panis. Some calculations have been made 

 respecting the number of hairs on the head and elsewhere ; these vary 

 according to the extent of the parts covered ; any given portion may 

 readily be examined by the microscope. The scalp contains about 200 

 in a square inch ; and, if we consider that the space covered contains 

 about 150 square inches, we have about 180,000 for the whole head; 

 next in numerical order, comes the face, then the pubis, then the fore- 

 arm, then the back of the liaud, and then the thighs. 



Some persons express surprise, that when hairs are pulled out by the 

 roots, they should ever grow again. It is readily explained by con-
