The right nostril is covered with dirty gray, partly dried secretion. Under the 

 tongue a croupous membrane has formed, being about 34 cm. 2 in size. 



March 26. — General condition bad. The hen lies on the bottom of the 

 cage in somnolent state ; occasionally it wakes up, rises and walks around, tak- 

 ing some food or water. The tumor in the right eye-lid has grown down the 

 fa("(^ ;is far as the wattles. It is soft and hot. The eye-lids are sticking to- 

 gether. By opening them, a large quantity of a purulent secretion exudes ; and 

 a clear jelly-like mass about one c.c.m.2 in size, can be removed from the depth 

 of the eye-lid. A pseudo-membrane, about 2-^ mm. thick, has formed on the 

 conjunctiva at the bulbus oculi, just over the cornea. On removal, the mucous 

 membrane beneath begins to bleed. The membrana nicticans is greatlj' swoll- 

 en. On the interior side a pseudo-membrane has formed about 4 mm. in size. 

 The Dseudo-membrane in the mouth has increased in thickness and size. A 

 purulent secretion exudes from the right nostril. 



ATarch 27. — General condition, better. The membrane on the ludbus oculi 

 lias reformed and the jelly-like mass in the lid sack has reappeared, but is now 

 turbid and gray. 



March 28. — The secretion from the nostrils smells offensively. The right 

 eye-lids are again sticking together, and the eye-lid contains a jelly-like, gray- 

 isih ma<;'5 



IMarch 29. — ^General condition is very bad. The eye-lids are sticking to- 

 gether and bulge out, because a yellowish-white, solid cheesy mass fills the 

 whole eye-lid. This mass has formed from the jelly-like mass, which had been 

 removed yesterday. 



April I. — Dead. 



Post-Mortem: Fairly well nourished carcass. Left eye normal. The 

 right eye-lid diffusely swollen. Between the partly opened lids a cheesy tumor 

 protrudes (See Fig. N. 11). It fills the whole eye-lid and can be removed 

 by pressing on the eye-lids. The conjunctiva gray and uneven. On the 

 upper eye-lid a small pseudo-membrane has formed ; similar membranes are 

 located on the outside and inside of left eye-lid. Small masses of solid yellow- 

 ish matter can be found in the subcutaneous tissue of the upper and lower eye- 

 lid. The nasal cavities are blocked up w-ith cheesy yellowish-white matter. The 

 right infra-orbital cavity is filled up with the same cheese-like substance. On 

 account of the pressure of this mass, the lateral bone-wall has disappeared, 

 and the cheesy mass lies directly under the skin of the face. The mucosa of the 

 nares is grey and \'ery soft. I'he mouth ontains sticky masses of saliwi ; 

 spleen and liver are small and normal. Cultures made from portions of these 

 organs remained sterile.

March 25. — General cundition is considerably disturbed. Eye-lids swollen, 

 conjunctivitis, on the upper lid is a small croupous membrane. Nostrils are 

 dirty. A small quantity of yellowish-white liquid can be pressed out of the 

 risht one. 



March 26. — The pseudo-ni<nibranc cm the eye-lid has spread upon the bulbus
