Dec. 19. — Discharge irom both nostrils. Nasal secretion is slimy and 

 putrid. 



Jan. 3, igo2. — Hen has lost very much flesh. All visible mucous mem- 

 branes are pale. General condition occasionally normal, but generally great- 

 ly depressed. Appetite always fair. On the mucous membrane in the mouth 

 is some sticky slime, and on both sides near the tongue there are two small 

 greyish-white pseudo-membranes about i mm. thick. They can be easily 

 removed. The mucous membrane under them is uneven, red and begins to 

 bleed at various spots. 



Jan. 8. — Pseudo-membranes have disappeared from the mouth. The left 

 nostril is entirely closed by a dry, yellowish-white, cheesy mass, which can 

 only be removed with difficulty, when the surface underneath bleeds. This 

 diseased part was treated with a 2>4 per cent, solution of Creolin. 



Jan. 9. — At the place treated with Creolin yesterday, a new pseudo-mem- 

 brane has formed. Treatment again renewed. 



Jan. II. — The left nostril again blocked up by the cheesy yellowish mass. 

 In many places in the mouth, thin, grey pseudo-membranes and at two places 

 on the left side of the mouth yellowish-wihite patches of croup-membranes have 

 formed. 



Jan. 14. — Both nostrils are free from any secretions, but the disagreeable 

 smell continues. At several places in the mouth, small pseudo-membranes 

 may be seen. General condition, fairly good. 



From 15th of Jan. to 3rd of Feb. — Chronic catarrh of both nostrils, some- 

 times with serous, and at other times with much pus. From time to time, 

 the discharge from the nostrils may stop for one or a few days. There is 

 always a very bad smell present. Very often pseudo-membranes appear 

 in the mouth, especially on both sides near the tongue, around the entrance 

 into the larynx, or on the palate, etc., for one or a few days. They never 

 grow larger than 1-4 cm. The general condition was always disturbed, some- 

 times more, sometimes less, with loss of flesh and anaemia. 

 Feb. 3. — Killed with chloroform. 

 Post-Mortem : Thin carcass. 



Conjunctiva and mucous membrane 01 the mouth very pale, without pseudo- 

 membranes. Nostrils are filled with dirty grey dried secretion. The mucous 

 membrane in the regio olfactoria is very soft, red and swollen. It shows at 

 several places, small, bloody extravasations. It is covered with a grey, slimy 

 mass mingled with pus and bloody streaks. The lower parts of the nasal 

 canals are blocked up with a mass, consisting of putrid slime, and solid granu- 

 les of solid white pus. The whole mucous membrane and submucous tissues 

 have disappeared. The cartilage of the left oral concha is at several places 

 black, dry and necrotic, or grey with very bad smell. In the dorsal wall of 

 the pharynx and the mucous membrane of the higher third of the oesophagus 

 are very many lymphoid follicles, swollen and filled with a yellow ciheesy mat- 

 ter. They extend often as deep as the muscles and consist of pus corpuscles 

 and four different kinds of germs (short thick rods, single or generally two 

 together ; long chains of another germ ; streptococci and staphlococci). The
