there is olten lurmcd in the inner corner of the eye a viscous, kicrymal secre- 

 tion, which contains air-'bubbles. These bubbles come from the nose, and are 

 forced into the eye through the lacrymal duct, because the natural air-passage 

 through the nostrils is half stopped up and the air finds this outlet. 



Soon a serous Conjimctivitis forms. The Conjunctiva becomes very moist. 

 swollen and grey. The secretion gradually assumes a slimy, purulent condi- 

 tion. The lids well oedematously. and become perceptibly thicker in a single 

 night. They are hot. sore, very much inflammed, and stick together very 

 easily, because the eye at this stage of the disease is, for the most part, kept 

 shut. Often the lacrymal duct remains open, and the secretion passes out 

 into the nasal or pharyngeal cavity. In all the more severe cases, however, 

 this canal is completely closed. The accuinulating secretion frequently over- 

 flows into the inner corner of the eye, and defiles the surrounding region with 

 greasy crusts of dried secretion. The small feathers on the side of the head 

 stick together, and often fall out. When the lids stick together, they are 

 forced outwards by the masses of secretion formed under the eye. The se- 

 cretion consists of a somewhat thin, clear, or turbid fluid, containing jelly-like 

 lumps, which are clear or striped with grey. The gelatinous masses are 

 formed by a homogenous, or lightly striped, unstainable substance, mingled 

 with pus corpuscles, epithelial cells, and bacteria. The grey parts are much 

 richer in leucocytes than the clearer ones. The epithelial cells ars ciliated, 

 with or without a swollen unstainable nucleus. The free epithelial nuclei are 

 usually very much swollen (as large as i6m.m.m.), round. Iiomogenous. or 

 slightly granular and unstainable. In the centre of the nucleus there may be 

 found one or two small, round bodies which can be stained. 



Tf the secretion is left in the closed eye-lid, it may be completely changed 

 in 24-4S hours to a firm, smooth, yellowish-white, cheese-like body, which fills 

 up the whole eye-lid. and lies like a cap over the bulbus ocnli. This chee-y 

 mass may become so large that it forces the lids open, and projects between 

 them. The outside then dries and becomes a brownish crust. Moore ex- 

 plains the formation of these cheesy masses by assuming that the liquid con- 

 tent of the eye-lid undergoes coagulation ; but. as stated above, they (the 

 cheesy masses) are formed from jelly-like masses in the eye-lid. In all prob- 

 ability, the secretion is an abnormal product of the lacrymal glands and con- 

 junctiva, and contains epithelial cells, as well as free swollen epithelial nuclei. 



The grey spots of these gelatinous masses contain very many round cells. 

 The greyer, firmer, and more turbid this mass becomes, the more numerous 

 are the cells. When the mass finally assumes the cheese-like appearrmce. it 

 consists of leucocytes, granular detritus, epithelial particles, and bacteria. 

 The yellow cheese-like masses are produced by the pus corpuscles exuding in 

 large numbers on to the surface of the mucous membrane, where they stick 

 together, mix with the pathologic secretions, and probably with coagulable 

 plasm. If the gelatinous masses are removed from the eye-lid and allowed 

 to dry. they become a dirty, grey crust. 



It is astonishing with what rapidity cheesy masses that have been removed 

 form again. Thus, from lien ri, cheesy masses, the size of marbles, were re-
