the same thermometer had been used during this time, and had 

 been for six years in the same place: the thermometer was 

 within the house, and had this summer reached 96° and 97°. 

 He believed it to have been the warmest period within his re- 

 collection. 



Mr. G. W. Smith cited several years in which the tempera- 

 ture had been very high. 



Dr. Patterson remarked, that Mr. Bull had just mentioned 

 to him that he had, in 1818, carefully examined a thermometer 

 fairly placed in the shade, and found it to rise, on three suc- 

 cessive days, to 103°. Dr. P. also mentioned, that upon the 

 occasion of an alteration in the University buildings in this 

 city, while the workmen were busy upon the roof, he had the 

 curiosity to take a thermometer to the roof, where he found 

 that the temperature was 137°. Upon a dark gravelly soil at 

 the University of Virginia, he found the temperature between 

 160° and 170°. 



Dr. Coates mentioned some experiments, tried by wrapping 

 a thermometer bulb in black wool, and exposing it to the sun's 

 rays: he succeeded several times in raising the temperature to 

 130°, and once to 142°. He also put the thermometer, wrap- 

 ped in black wool, in a window with inside shutters, and with 

 a westwardly exposure; at about 4 o'clock, P. M., the tempe- 

 rature rose to 172°. 



In consequence of the want of a sufficient number of mem- 

 bers, no ballotting for candidates for membership took place. 



Dr. Patterson, from the Committee appointed to consider 

 the application of the Councils and the County Board, for the 

 purchase of the Hall, stated, that one of the members of the 

 Committee was absent from the city, and asked that another 

 member be added to that Committee, which was granted, and 

 Mr. Ord was appointed upon the Committee.
