Many experiments have been made to determine whether 

 any difference exists between the blood o/ males and females. 

 From the trials of Lecami it follows that the proportion of albu- 

 men in both is sensibly the same. 



In man. In woman. 



Maximum, . 78-270 74-740 

 Minimum, . 57-890 59-159 

 Mean, . 68-080 66-9495 



The proportion of globules is greater in the blood of men than 

 in that of women. 



In man. In woman. 



Maximum, . 148-450 129-999 

 Minimum, .. 115-850 68-349 

 Mean, . 132-150 99-1695 



The proportion of water is greater in the blood of women than 

 of men. 



In man. In woman. 



Maximum, . 805.263 853-135 

 Minimum, .. 778.625 790-394 

 Mean, . 791*944 821-7645 



With respect to temperament, the blood contains more water 

 in persons of a lymphatic than of a sanguine temperament ; the 

 proportion of albumen is nearly the same in both, but the glo- 

 bules are more numerous in the blood of sanguine than of lym- 

 phatic individuals. 



When blood is repeatedly drawn from the same individual 

 the proportion of water increases, while that of the globules di- 

 minishes after each bleeding. This was ascertained by M. Le- 

 canu* and by Dr Andrews, f 



In the case of uterine hemorrhagy the proportion of water is 

 greatly augmented, while that of the globules, and even of 

 the albumen is much diminished.^ When the nourishment is 

 diminished, the water in the blood increases, while the globules 

 diminish. The albumen is not much altered in quantity. 



Many experiments have been made to ascertain whether any 

 difference exists between venous and arterial blood. The follow- 

 ing table exhibits the specific gravity of each as determined by 

 different experimenters :
