316 TRANS UDAT10NS. 



quantity of albumen, He found the transudation in the 

 pleura to be richest in albumen (= 2'85-g-) ; that in the peri- 

 toneum considerably poorer (=l'13-g-); that within the cranial 

 membranes yet more deficient in this constituent (0*6, or at most 

 0'8%) ; and that of the subcutaneous cellular tissue the poorest 

 (=0*36^). Schmidt found this proportion of the albumen to the 

 effused fluid in the transudationsof one and the same individual, who 

 was suffering from Bright' s disease ; and he convinced himself by 

 further investigations regarding the normal transudation of the 

 cerebral capillaries and hydrocephalic effusions, that not only does the 

 quantity of albumen always remain tolerably equal when there is 

 an excess of the transudation, but also when, after the removal of 

 older effusion, a new transudation occurs through the same capil- 

 laries. In the normal cerebro-spinal fluid of a dog, Schmidt found 

 0-24^ of organic matter; in chronic hydrocephalus of a child, at the 

 first and at a second paracentesis, 0'156-|} and 'I79r ; an( ^ ln 

 acute hydrocephalus 0'37-g-, 0'649<}, and 1'040-g- ; in a pleuritic 

 transudation, obtained by paracentesis, 2'61-J; in that obtained 

 after death from the same person, 2 '85-g; in the first peritoneal 

 transudation, obtained by paracentesis, 0*365; in the second, 

 from the same person, 0'395f. I collected 33*8 grammes of 

 transudation from the pericardium of a perfectly healthy criminal 

 within three minutes after his decapitation ; it contained 0'879 -$ 

 of albumen, with 0'093^ of other organic matter, and 0'089-g- 

 of salts. In the fluid, in a case of hydropericardium ex vacuo 

 (in pulmonary tuberculosis), I found 1'543^ of albumen. 

 In examining the dropsical transudations in the dead body of a 

 drunkard with true and well-developed granular liver, I found, in 

 the fluid of the pericardium, 1*063^ of albumen; in that of the 

 pleura, l'852-g-; in that of the peritoneum, 1'044-g-; and in that of 

 the cerebral ventricles, 0'564-g-. In a peritoneal transudation, in a 

 case of cancer of the liver (where the liver extended two inches 

 below the navel), I once found 4'351^ of albumen, besides O598J 

 of extractive matters, and 0*890- of salts; while, on the other 

 hand, in hydrsemia (consequent on chronic ulceration of the follicles 

 of the large intestine), I have found only 1*1 27# of albumen, with 

 0'448-g- of extractive matters, and 1'014-g- of salts. In the trans,- 

 udation from the cerebral capillaries, in hydrocephalus ex vacuo 

 (cerebral atrophy in an old man), I found 0*144 -g-; in congenital 

 hydrocephalus, 0'012^; and in hydrocele, 6*283J, 4'982-J, 4'055-g, 

 and 3*4 10 of pure albumen.
