On the Effects of Inoculation; the Eclipse of the Sun in November 1722; and 

 the Fenom of Spiders. By Mr. Tho. Robie, Physician in Neiv England. 

 N"382, p. Qj. 



They had not hitherto observed any ill effects of inoculation in New Eng- 

 land; the inoculated being as well, and some of them a great deal better than 

 ever. As for the ill consequences that have been in England, Dr. R. can hardly 

 think they are the genuine effects of inoculation, but may arise from some 

 previous disposition to distempers, or for want of due evacuations after inocu- 

 lation, and too soon healing the places of incision. 



As to the great eclipse of the sun in November last. Dr. R. observed it 

 Nov. 27, 1722, at 7''27"' morn. He saw the sun rise eclipsed, on its supreme 

 vertex to the south, about 4 digits, though some on the top of the new college 

 saw it 2 or 3"^ before. The sun's true rising this morning was 7*^ 30"" ; hence the 

 refraction is about 6'. From this time, till about S*' SO'" or 40"", he saw no 

 more of the sun, but then he judged it was eclipsed 6 digits or more. 



At g*" 25"^ 45* he saw the moon go off the sun. 



At g^ 25*" 45% Mr. Danforth, in a room just by, saw the shadow go off the 

 paper about 30° from its lower vertex to the east. 



At Q^ 25'" 20% Mr. Appleton saw the shadow go off the paper fixed to the 

 college brass quadrant at his house. 



Mr. Owen Harris, an ingenious schoolmaster in Boston, says, he observed 

 the end at about 26™ past Q. 



At Boston the eclipse was observed, allowing for its distance, as Dr. R. ob- 

 served it at the college. And at Barnstable, on Cape Cod, there was but a 

 little left of the sun, and nearer the head of the cape there was a ring of light 

 quite round the moon. 



Dr. R. gives an account of a remarkable accident relating to the venom of 

 spiders, Sept. 13, 1722, one Nat. Ware of Needham was bit by a small spider, 

 which he could not give an exact description of, crushing it to pieces between 

 his stocking and leg. The account he gave is this, viz. that getting up early 

 in the morning, and putting on his stocking, he presently felt something bite 

 his left leg a little above his ancle, about half an hour after he felt a pain in 

 that leg, and about half an hour from his first perceiving pain in his leg, he 

 felt a pain in his groin, and at the same time a creeping pain in the calf of his 

 left leg; and about one hour after it got into the small of his back, and then
