other fevers, manifestly retarded the progress of this ; and if the sweat was 

 encouraged for 5 or 6 hours, by laying on more clothes, or taking some sudo- 

 rific medicine, most of the complaints would entirely disappear, or at least very 

 much abate. The giddiness of the head and want of appetite would often 

 continue some days after, but with the use of the open fresh air, they certainly 

 in 4 or 5 days at farthest recovered, and were perfectly well : so transient and 

 favourable was this disease, that it seldom required the help of a physician ; and 

 of 1000 that were seized with it, I believe scarcely one died; and by the middle 

 of August following it wholly disappeared ; so that its whole period was about 

 7 weeks. 



This fever also spread itself all over England ; and it raged as generally in 

 London as in Dublin, and with the same symptoms, but with some difference 

 of time in relation to its first appearance ; for whereas they began to take no- 

 tice of it at London about the middle of May, and it continued there till about 

 the latter end of June ; it did not show itself here in Dublin till the beginning 

 of July, after it had wholly disappeared in London. So likewise our late gene- 

 ral colds, as beforementioned, were observed to keep such a sort of regular 

 precedence of time, as to their rise and fall at London, in respect of Dublin. 

 Whence we may reasonably infer, that these spreading epidemic distempers 

 take their progress from east to west. But this should be further confirmed by 

 more frequent observations, before we may safely determine any thing on this 

 head generally : however, that it held true in the two foregoing instances is 

 certain : and it is not less certain that the plague and pestilential fevers rage 

 more frequently in the east towards Constantinople and the Levant, than in 

 these more western parts of Europe.

After throwing up the sternum, and inspecting the parts contained in the 

 cavity of the breast, I found the lobes of the lungs extremely turgid, and its 

 vesicles replete with a grumous blood, and their investing membrane in the 

 upper part adhered firmly to the pleura ; the right ventricle of the heart was 

 filled with a large quantity of coagulated blood, but the left seemed exsanguinous : 

 I took but a cursory view of these parts, yet I could not but observe a stagnation, 

 and great extravasation of blood upon the right side of the pleura. 



Beneath the diaphragm, in the cavity of the abdomen, I found the ventricle 

 and intestines much inflated, the omentum fair and large, and the spleen so 

 much augmented in bulk, that it could not weigh less than 2 or 3 pounds ; 

 upon cutting through its body, there was discharged several ounces of a very
