niensles. She was treated accordingly, and got well; excepting a pretty severe 

 coiigli she had, whicli continued through the whole course of the following 

 small-pox. About the J '2th day she sickened again, and about the 14th the 

 small-pox appeared, the distinct kind, and very favourable; they came out, 

 filled, and dried away very kindly, and were attended with very little of a second 

 fever. She went through the distemper with a great deal of cheerfulness; she 

 was purged afterwards, and seemed very well ; but in a little time after, a boil 

 came on the lower part of the shoulder-blade of the same arm that was inocu- 

 lated, which was brought to suppurate, and was healed in the common 

 manner. 



From this subject Mr. Wright inoculated two daughters and a son of 

 Nicholas Roch, Esq. at his seat, about 5 miles from this town. These 3 chil- 

 dren were from 3 to 8 years of age. The incision was made in one arm of each 

 child; it produced the same effect on every one of them as it did on Miss 

 Kymer, viz. the measles on the 7th or 8th day, and the small-pox of the dis- 

 tinct sort on the 14th. They went all three very well through every stage of 

 the distemper; the secondary fever was but slight. One of these had them 

 somewhat thick, and the other two had a good many of them; but they all 

 thoroughlv recovered, and have all since continued in a good state of health.

There is nothing remarkable in this journal, or different from many other 

 sea journals, of the daily latitudes and longitudes, heights of barometer and 

 thermometer, the winds and weather, with the regular variation of the coni- 

 pass. This gradually and regularly increased on the outward voyage, beginning 

 the account with the latitude 59° 1 7', and longitude 5" 32', where the variation 

 was found 17° 30'; from thence increasing with the longitude, till the varia- 

 tion was the greatest, viz. 43°, in long. 72° and lat. 63°. After this, the varia- 

 tion gradually decreased as the latitude decreased, though the longitude in- 

 creased, till it came down to 24°, which was in lat. 57°, and long. 85.^°. After 

 this, the variation gradually increased again, till it became 42°, viz. in lat. 63", 

 and long, about 70*^. Lastly, it gradually decreased again, on the returning 

 voyage, till it was 14", viz. in lat. 49^°, and long. 5°. 



Capt. Middleton remarks that, when they come in or near ice, they are 

 obliged to keep one of the compasses lontinually moving, there being either 

 some magnetic particles in the air, or some other quality that hinders them
