GENERAL DISEASES. 51 



times swollen and tender to the touch. The pulse is feeble 

 and frequent, and the thermometer indicates a variable 

 elevation of temperature. In a few days the temperature 

 may rise to 105° or 106° ; the pulse may reach 60 — 80 beats 

 per minute, and the respirations become accelerated. The 

 other symptoms also increase in severity : the cough becomes 

 deeper and deeper ; the throat becomes sore, and difficulty 

 of swallowing follows in consequence. 



The debility and prostration becomes more intense, and 

 thirst is marked. The nasal mucous membrane, at first dry, 

 becomes moistened, and there is a discharge of mucus. The 

 bowels are sluggish, the fa3ces become hard and coated with 

 mucus, and the urine is scanty and high-coloured, often 

 containing albumen, or excess of urea and hippuric acid or 

 of urates. 



In about a week the symptoms gradually abate. The nasal 

 discharge increases in amount, becoming thicker and purulent. 

 The cough is moister, and the temperature falls by lysis, 

 and convalescence_is established in about fourteen days from 

 the onset ^f tjie fever^ 



Sometimes, however, recovery is retarded, and the pyrexial 

 symptoms recur. This is owing to the implication of the 

 glandular structure around the throat, and of the neigh- 

 bouring connective tissue, terminating in suppuration in 

 the submaxillary and parotid glands, or in the surrounding 

 tissue. 



A Special form of Catarrhal Influenza, known by the 

 names of ' pink eye,' ' pneumo-enteric fever,^ ' epizootic 

 cellulit is,' has of late been very prevalent. By some it has 

 been regarded as a distinct disease, but it is probably 

 only a modified form of simple influenza. In this form, 

 the conjunctiva is of a pinkish colour, and in many cases 

 the sub-conjunctival tissue is infiltrated with hoemorrhagic 

 exudation. The constitutional symptoms are sometimes
