acute than the voice of men. The voice of female children 

 also is more acute than that of males, and the windpipe is 

 more acute in girls than boys. 



4. They also want especial care at this period, for their 

 sexual desires are very strong at the commencement, so 

 that if they now take care to avoid every excitement, except 

 such as the change of their body requires, without using 

 venery, they generally remain temperate in after-years. For 

 girls who indulge in venery when young, generally grow up 

 intemperate ; and so do males if they are unguarded either 

 one way or both ways ; for at this age the ducts open, and 

 afford an easy passage for the fluid through the body, and 

 at the same time the memory of past pleasures causes a 

 desire for present gratification. 



9. Some men never have hair on the pubes from their 

 birth, nor seed, on account of the destruction of the parts 

 appropriated to the semen. There are some women also 

 who never have hair on the pubes. The male and female 

 also change their habits of sickness and of health, and 

 the proportions of their body, whether slight or stout, 

 or of a good habit. Some thin boys after they attain 

 puberty become stout and healthy, in others the contrary 

 takes place. This is the case also with females ; for whe- 

 ther boys or girls have their bodies loaded with excre- 

 mentitious matter, this is separated in the one by puberty, 

 in the other by the catamenia. They become more healthy 

 and thriving when that which had prevented health and 

 growth is removed. 



6. Those which are of the contrary habit of body become 

 more thin and delicate ; for their naturally healthy condi- 

 tion is separated in the puberty of one sex., and the cata- 

 menia of the other. There is also considerable variety in 

 the bosoms of young girls, for in some they are very large, 

 in others small. This generally takes place in those girls 

 which have much superfluous humour, for when the cata- 

 menia are about to appear, but before they arrive, the more 

 fluid the patient is, the more necessary it is that the breasts 

 should increase until the catamenia make their appearance, 

 and the breasts, which then begin to increase, remain so after- 

 wards. In youths and aged men the breasts are more con- 

 spicuous, and more like those of females ; and in those who
