General Diseases. 301 



only when the animals had survived more than twenty-four 

 hours was there observable anything in the form of the 

 peculiar and characteristic grey coagulated exudation ; 

 this being sometimes in spots, and at others in considerable 

 stripes, but always adherent to the mucous membrane. 



" More frequently the exudation, which was always pre- 

 sent, was a glossy, tenacious, soft, structureless, or granular 

 material, more thickly deposited on some parts than 

 others. 



" Another form or type in which the disease manifested 

 itself was that where the febrile disturbance seemed scarcely 

 so severe, the extension of the local diseased action less 

 rapid, and the power of swallowing never entirely gone ; 

 but where the glands of the throat and cervical region were 

 early swollen, and increased in size rapidly, together with 

 extensive infiltration of the connective tissue in which these 

 gland-structures are embedded. In such there was from 

 the first marked stiffness of the neck and greater restless- 

 ness until coma supervened. 



•' A third class, again, exhibited what may most fitly be 

 termed the ' nasal type.' After a certain amount of dulness, 

 and fever of a lower character than was met with in either 

 of the other forms mentioned, there would appear evident 

 sore throat, with a discharge of a sanious material from the 

 nostrils. On examining the mouth, material of a similar 

 nature, but more watery from mingling with the saliva^ 

 might be seen bubbling over the tongue from the fauces. 

 Cases of this form survived longest ; and in them only did 

 we find sordes on the teeth and lips, the breath becoming 

 foetid and the lymphatic glands, much swollen. The after- 

 death examination of these showed that the disease had 

 extended — whether from continuity or separate centres was 

 impossible to say — into the posterior nasal channels. 



" The infiltration, however, of the submucous tissue and 

 exudate, in connection with the membrane, was always 

 most distinctive in the pharynx and at the pillars ol the
