234 Progress of Rational Pathology. 



exsudation, of the form of the epiglottis (?) is expectorated with 

 a violent cough that often lasts for hours, and with excessive 

 difficulty of breathing preceding it. — The seat of pneumonia, 

 according to the consent of most modern authors, is in the 

 mucous coat of the minutest lung-cells, and the granulations 

 of hepatised lungs are formed by the filling of these cells 

 with exsudation : on this account they are largest in full 

 grown and in emphysematous lungs. 



o. Kidneys, — Bright's disease is, according to Henle, amor- 

 bid action exactly similar to that of cirrhosis of the liver : in 

 both, elementary granules, fat, and cellular tissue in its various 

 stages of development, are found between the elementary parts 

 of the glands, in both is the gland at first thereby swollen, and 

 becomes afterwards atrophic, and granular by their contraction. 

 Of both, there is an acute and a chronic form : the first of 

 these appears to differ from pure congestion and inflammation 

 of the kidney only in degree and in extent, and perhaps also 

 in the source of the exsudation, in as much as it is thrown 

 out chiefly by the arterial portion of the capillary system in 

 pure inflammation, chiefly by the venous in cirrhosis and in 

 Bright's disease. The various forms of Bright's disease des- 

 cribed by different observers, are only stages of the same 

 affection. 



p. Eyes. — Although many writers speak of alterations of 

 the corpus papillare of the conjunctiva in blennorrhoea of 

 the eyes, yet Engel and Henle prove that they do not 

 take place. What has been called hypertrophy of it, consists 

 in the plastic matter, deposited upon and in the tissue of the 

 conjunctiva, becoming organised. Nasse calls attention to 

 a form of inflammation of the cornea in women who are 

 nursing, which at first attacks only one eye, and is re- 

 markable from its tendency to form ulcers : he thinks that 

 it is caused by impoverishment of the blood, (anaemia from 

 excessive secretion of milk, like keratitis in animals whose 

 blood has lost its fibrine.) Schroder van der Kolk regards a
