Concerning a quarry of Marble, discovered in the Count]/ of Farmanagh in 

 Ireland. By Francis Nevill, Esq. N° 337, art. 36, p. 278. 



I discovered a marble quarry in the mountains. It lies on the north side of 

 Calcagh, in the parish of Kilasher, and county of Fermanagh. There are 

 marble rocks, whose perpendicular height is 50 or 6o feet, discovered by sub- 

 terraneous rivers, which have gradually washed away the earth and loose stones, 

 and discovered these vast rocks. There are many great pits fallen in, on the 

 sides of the great mountain ; several of them in a small compass of ground ; so 

 that it is dangerous travelling near them. There are many caves formed, some 

 very large, the sides and arches of marble ; some of a liver colour, varied with 

 white in many little figures; some of a light blue, varied with white; but I 

 could find no entire white or black among them. 



Remarks on the Plague at Copenhagen, in the Year 1 7 1 1 . By John Chamber^ 

 layne, Esq. F. R. S. N° 337, art. 37, p. 279. 



This distemper began to show itself first in this city, about the beginning of 

 July, 1711 ; and increased till the beginning of September; after which it 

 gradually diminished to the end of the year, at which time it totally ceased. It 

 appears, that before this distemper there were about 6o,000 souls in Copen- 

 hagen : from whence they infer, that there is born every year about 2000, and 

 that there dies nearly the same number; which being multiplied by 30 makes 

 60,000. 



In the 6 months which this distemper continued, it is thought it carried ofF 

 about 25000 souls. It is true, the public lists reckon only 22535 ; but it is 

 agreed by all, that in the last week of August, and the first two weeks of 

 September, each of which carried off above 2300 souls, there died a great 

 many, of which no notice was taken. 



Almost the very same happened 2 years before at Dantzic ; where, before 

 the plague broke out, there died weekly from 45 to 50 ; but the number of the 

 dead increased gradually to the beginning of September; so that in the first 

 week of that month there died 2205 souls, in the second week 207(), and in 

 the third 2075. After which the mortality decreased to the end of the year. 



It is observable, 1. That there were some houses which escaped the in- 

 fection; but that there were few where it did not carry off more than one or two 

 persons ; and that there were many in wliich it did not leave a soul alive. 

 2. That, generally speaking, this distemper was most fatal to the meaner sort of 

 people; scarcely any person of note dying; but on the contrary a great number
