140 PROPORTION OF HAEMOGLOBIN IN VARIOUS DISEASES. [BOOK I. 



In health, the amount of haemoglobin in the blood appears to be pro- 

 portional to the number of corpuscles. This relation does not hold, 

 however, in disease, as will be particularly mentioned in discussing the. 

 phenomena of anaemia. 



The largest number of determinations of the amount of haemoglobin 

 in the blood of various diseases has been carried out by Quincke 1 , who 

 made use of Preyer's method for the determination of haemoglobin. In 

 the annexed table may be seen the results which he obtained. The letters 

 V-S. in the second column indicate that the blood was obtained by vene- 

 section, and the letter H that it was obtained by Heurteloup's artificial leech.
