m. Pancreas, according to Claessen, the symptom of acute 

 pancreatitis is, a slight kind of drawing together pain, united 

 with remarkable anxiety, which bears no proportion to the 

 violence of the accompanying stomach symptoms. The tongue 

 is moist and clean or with a white coating ; the fever trifling. 

 Resolution and induration of the organ have been observed as 

 its sequelae, never suppuration or gangrene. This inflamma- 

 tion does not appear to arise, as some have supposed, from the 

 use of mercury, or from the suppression of the salivary flow, 

 indeed the sympathy between the pancreas and the salivary 

 glands has been assumed without warrant. Chronic inflam- 

 mation shews itself by pain, copious dejections and vomiting 

 of watery and slimy fluid (coining from the stomach) loss of 

 appetite, excessive thirst, obstinate constipation and falling 

 away. 



n. Organs of respiration. Angina externa comes on, 

 with or without slight fever, or with a feeling of lassitude 

 and rheumatic pains, as a hard swelling, but neither hot, 

 red nor painful in the submaxillary, parotid, or laryngeal 

 region especially of the left side. As it increases, difficulty 

 of speaking and of swallowing occur, but without any inflam- 

 matory symptoms in the mouth or lining of the air passages : 

 there is in addition fever with nightly exacerbations. The ter- 

 minations are, resolution, or death with the symptoms of 

 putrid fever by suffocation, either before or after evacuation of 

 the contents of the swelling. The fluid evacuated is ichorous. 

 Either gangrenous destruction of the cellular tissue (of the 

 muscles and nerves in the neighbourhood, not of the salivary 

 glands) or infiltration of it with lymphatic albuminous fluid, are 

 found after death, or both. Henle sees in this inflammation 

 an excellent example of obstructed action in the absorbents ; 

 but this obstruction is distinctly related to the rheumatic pro- 

 cess ; its most usual exciting cause is exposure to cold. Hen- 

 nemaen names as epiglottitis chronica exsudaliva, a disease, 

 in which from time to time a whitish crust of inflammatory
