GENERAL DISEASES. 283 



''Post-mortem examination of these cases showed that 

 only when the animals had survived more than twenty-four 

 hours was there observable any thing in the form of the pecu- 

 liar 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 pres- 

 ent, 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 exten;.io;i 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 swol- 

 len, 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 restlessness 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 nos- 

 trils. 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 con- 

 tinuity 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 of the soft palate.
