CIRCULATING FLUIDS: 



[Becquerel and Rodier liave analysed the blood of 13 persons 

 attacked with typhoid fever^ 11 men and 2 women. Of the 

 11 men, 6 were bled once, 4 twice, and 1 thrice; of the 

 2 women, 1 was bled once, and 1 thrice. 



The following table exhibits the mean composition of the 

 blood of the male patients, obtained at the first venesection :

The fibrin varied considerably, the maximum being 4-9, 

 while in three cases it was considerably below the normal 

 standard. The albumen and blood-corpuscles were, in most 

 instances, diminished. 



Four of the same men were bled a second time, and the fol- 

 lowing table gives the mean results of the blood obtained in 

 these four cases, on both occasions
