BLOOD.

The blood contained, mucTi to my surprise, a larger amount 

 of solid constituents than I have ever obsened in any other 

 analysis. The fat, when isolated, smelt strongly of the volatile 

 fatty acid of the cod-liver oil, the odour of Avhich was also 

 strongly developed during the evaporation of the blood to dry- 

 ness. A considerable quantity of hsemaphsein was present, and 

 deeply coloured the extractive matters and salts. It is very pro- 

 bable that the pecuKar changes in the blood in this instance are 

 due principally to the cod-liver oil and to the repeated bleedings. 



Andral and Gavarret have analysed the blood in 21 cases of 

 this disease. Then' maximum of fibrin was 5*9, their minimum 

 2"1. In only two instances did the amount of corpuscles ap- 

 proximate to the normal standard, as fixed by Lecanu : in these 

 two cases it Avas represented by 122*1 and 120"4 respectively. 

 The amount was frequently below 100, and the decrease of cor- 

 puscles was almost always found to be accompanied v,ith a cor- 

 responding increase of fibrin. 



The maxima, minima, and average of the various constitu- 

 ents, as deduced from 22 analyses, made by Andral and Gavarret, 

 are given in the following table :

This table shows the great difference that may exist between 

 the quantities of the soHd constituents, and of the corpuscles, 

 in healthy and in diseased blood. 



[Becquerel and Rodier examined the blood of nine persons 

 atfected with pulmonary phthisis, \az. five men and four women.

 blood of the men :
