152 PRACTICE OF PHYSIC. 



face ; and the liquids of the mouth and throat becoming thick- 

 er, are more difficultly thrown out. There is, at the same time, 

 some difficulty of swallowing, so that liquids taken in to be 

 swallowed, are frequently rejected, or thrown out by the nose. 

 But all the affections of the fauces abate as the swelling of the 

 face subsides. 



DXC. In the other form of smallpox, or what is called the 

 Confluent, the course of the disease is in general the same with 

 what we have described ; but the symptoms of every stage are 

 more violent, and several of the circumstances are different. 



In particular, the eruptive fever is more violent ; the pulse 

 is more frequent and more contracted, approaching to that state 

 of pulse which is found in the typhus ; the coma is more consid- 

 erable, and there is frequently a delirium. Vomiting, also, is a com- 

 mon symptom, especially at the coming on of the disease. In very 

 young infants, epileptic fits are sometimes frequent in the first days 

 of the disease, and sometimes prove fatal before any eruption ap- 

 pears ; or they usher in a very confluent and putrid smallpox. 



DXC I. The eruption appears more early on the third day, 

 and it is frequently preceded or accompanied with an erysipela- 

 tous efflorescence. Sometimes the eruption appears in clusters, 

 like that of the measles. When the eruption is completed, 

 the pimples are always more numerous upon the face, and at the 

 same time smaller and less eminent. After the eruption, the fe- 

 ver suffers some remission, but never goes off entirely ; and after 

 the fifth or sixth day, it again increases, and continues con- 

 siderable through the remaining course of the disease. 



The vesicles formed on the tops of the pimples appear soon- 

 er ; and while they increase in breadth, do not retain a circular, 

 but are every way of an irregular figure. Many of them run 

 into one another, insomuch, that very often the face is covered 

 rather with one vesicle than with a number of pustules. The 

 vesicles, so far as they are anywise separated, do not arise to a 

 spheroidical form, but remain flat, and sometimes the whole of 

 the face is of an even surface. When the pustules are in any 

 measure separated, their circumference is not bounded by an 

 inflamed margin, and the part of the skin that is free from pus- 

 tules is commonly pale and flaccid. 



The liquor that is in the pustules changes from a clear to an
