12 General Pathology. 



There is a false membrane extending from the base of the 

 epiglottis through the larynx to the trachea. In some places 

 it is detached, and has left the mucous membrane below 

 apparently little changed. G. C. 683.

1, 38. Lymph on Cutaneous Surface— Burn. 



Specimen required.

Nine months before death (from strangulated hernia) patient had 

 suffered from an attack of localised peritonitis from which he seemed

 now well formed, and has, no doubt, resulted from a slight 

 peritonitis, which must have occurred some years before

1. 41. Thickening" in Subcutaneous Tissue.— Portion of skin, 

 with subcutaneous tissue, taken from the foot of a man, who 

 had suffered from ulcer of the leg for many years. 



The subcutaneous tissue is very dense and firm, from the
