BLOOD. 335 



puscles lying closely attached to eacli other, while the chyle- 

 corpuscles almost always swim about separately. By this means 

 I have recognized pus in the blood, both when it has been arti- 

 ficially placed there, and on analysing the blood which I took 

 from the inflamed vein of a person who had died from plilebitis. 



In one instance, in which I found a considerable quantity of 

 pus in the blood, taken from the inflamed vein in a case of 

 traumatic phlebitis, I could detect no traces of pus in the blood 

 taken from the vena cava and from the heart. 



This is all that I can state from my own experience regard- 

 ing the detection of pus in the blood. 



VI. ANIMALS IN THE BLOOD. 



Early authors speak of living animals in the blood. Dr. Chiaje,i 

 of Naples, has recently stated that he found the polystoma san- 

 guiculum in the expectorated blood of two phthisical patients 

 who were attacked with haemoptysis. Some of these small flat 

 worms, which are similar to leeches, were floating about in 

 the serum, others attached themselves to the sides of the vessel. 

 Chiaje characterizes the polystoma in the following terms : " Cor- 

 pus teretiusculum, seu depressum, pori sex antici ventrales, et 

 posticus solitarius ; habitat in venoso systemate hominis, et prae- 

 sertim in ejusdem pulmonali parenchymate.'^ 



[Dr. Goodfellowhas lately recorded a case in which an immense 

 number of animalculse were found in the blood of a fever-patient. 

 They varied in length from 1 -5000th to 1 -3000th of an inch, and 

 in diameter, which was the same throughout, from l-40,000th 

 to ]-20,000th of an inch. A singular case was observed by 

 Mr. Bushman, in which worms of about half an inch in length 

 were found in the blood of a boy labouring under influenza.

SUPPLEMENT. 



The following analyses of the blood of a pregnant woman (in 

 her fifth month), and of menstrual blood, could not be naturally 

 inserted among either of our four forms of diseased blood, and 

 will find a proper place in a supplement.
