What effects this drought has had on the bodies of animals, I leave others to 

 judge. It is well known how contagious and fatal a distemper has raged among 

 our black cattle, as also in many other parts of Europe. And I observed the 

 itch was epidemical among the poorer sort, at the beginning of the year; that 

 the measles were very common, some parts of the year; and that pleurisies and 

 malignant fevers, infested a great many, especially in the summer months. But 

 how far these distempers might be owing to the dry season, I leave to the judg- 

 ment of our learned physicians. 



To compare with these, we have collected from the Memoirs of the Royal 

 Academy of Sciences, the quantity of rain and dissolved snow which has fallen 

 at the Observatory at Paris for the same years; according to the observation of 

 M. De la Hire. And that the comparison might be made more justly, we have 

 reduced the French measure to our own. But it is to be observed, that the diver- 

 sity of stile makes the years not exactly the same, though, as to this matter, 

 the difference may seem very inconsiderable, the one being only between lO 

 and 1 1 days later than the other.

 The solution of the problems mentioned in these two articles being found in 

 Mr. Demoivre's doctrine of chances, in an improved form, afterwards pub- 

 lished, and in other books on the doctrine of chances, it were quite unprofitable 

 to reprint them in this place. 



• Nicolas was the second son of the celebrated John Bernoulli, who with his younger brother, 

 Daniel, pursued the same mathematical studies with their father. These two brothers were invited 

 to Petersburg on the foundation of the Academy, in 1725, where Nicolas died the year following, 

 at an early age, and was honourably interred by the Czarina.
