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 of the
