very vivid lightning. The lightning had a very purplish appearance. The storm continued for the space of twelve to fourteen minutes, after which it became perfectly calm. At 
7 a.m. th<- barom ter was much depressed, having fallen nearly an inch from the previous afternoon. It stood thus on the 2nd, at 3 r.M., F. 30.103, C. 30.100; and on the 3rd, at 
7 a.m. F. 20.324, C. 20.318 ; and it continued falling until the following day, when at 3 p.m. it began to rise.— J. D. R.
