seldom so overcast, as to obstruct the rays of the sun, for four days successively. 



The most intense cold which we experienced in the year 1804 was on the" 25th of January, being 14 6-lOths below 0; the gr 

 degrees ; and the medium temperature of the whole year, resulting from ohserv-ations made on every day thereof, was 55 2-lOthi 



In the year 1805, on the 12th and 25th of January, the mtrcury fell to 2 9-lOths below O ; on the 2d and 22d of August, it rose to 100 6-lOth: 



these two years, was much greater than of any year from 1787 to 1800 inclusive. 



THE most intense cold which we have had in Pennsylvania, between the first day of January 

 1787, and the first day of Februar)' 1 806, according to a regular series of observations made at Spring'- 

 Mill, every day at sun-rise and at two o'clock m the afternoon, the thermometer in the open air, suffi- 

 ciently shaded, about five feet from the surface of the ground, and out of the way of any extra reflec- 

 tion of the sun's rays, occasioned by w.-dls, pavements, &c. happened on the 2d of February 1789 ; the 

 ;ury having fallen that tlay, to 17 S-lOths degrees below zero or O Fahrenheit ; and the gi-eatest 

 heat during that period was in July 1793, when the mercury rose to 104 5-lOths degrees. July is ge- 

 rally, our hottest month, and our greatest degree of heat, on an average of several years, may be 

 tiraated at about 99 5-lOths. January is, usually, our coldest month, in the course of which, we 

 may always expect a degree of cold, equal to 1 S-lOths below 0. ^Pentive obser^'ations, at the 

 medium for one year, 4 d.ays of Aurora Bore.ilis, 16 of thunder, 7 of tempestuous weather, 16 of snow, 249 of 

 be 39 inches, 9 lines, and ll-ieths of a line, English measure. Our atmosphere is gener.-dly clear, and 



i observable that the medium heat oi each 



the 4di of May and 9lh of July, being on each of tliese days 

 and the medium temperature of the whole year, was 



xn grea 



i ; the most intense cold, betwe 



, to 3 4-IOths below ; in the j 



and the medium heat of the whole year, as established on the result of " 

 I 104, andin 1743,to99 5-10ths. The coldest month at that place is Jam 



In Paris, the greatest summer heat is, ^fnfra»^,Detween 92 7-lOths and 95 degrees ; the most intense cold, between 9 5-1 Oths 

 years observations, 51 8-lOths. But in the year 1716 the mercurj 

 aiy, and the hottest August. 



At Hoom, in Holland, in the year 1763, the mercury had fallen to 8 degrees, which is marked on some of the Dutch thermometeis, as a remarkable degree of cold. 



Ice or snow mixed with kitchen salt, produces a degree of cold equal to zero or of Fahrenheit. The point at which still water begins to freeze is 32, and is consequently, called the freezing point. Rivers 

 <.i' running waters, freeze at 20 7-lOths ; cider and vinegar at 1 1 7-lOths, and unadulterated wine M S degrees. The medium temneratiu-e marked on Botanical thermometers, as best adapted for the Pine- 

 Apple, IS 73 6-lOths i (or Melon-beds 69 1-lOth, and for an Orangery 57 9-lOths. 



The constant temperature of the cellar of the Obser\atory at Paris,' is 54 5-lOths ; which is generally considered to be the same, in even' part of the globe, at the depth of about 400 feet beneath the surface. 

 I he most salutar)' temperature of the sick orpatient's room, is thought to be 72 2-lOths. The heat ol'the human blood, in the opinion of the Faculty oi Medicine at Paris, is 99 5-lOths : on the English ther- 

 mometers. It is marked 98 ; and on several thermometers made in Holland and other places in tfie north o: Europe, 96. Heat ol Hen's incubation I'OS 2-lOths. Fever heat 1 12. Rain or distilled water boils 

 at 212 degrees, when the mercur>' in the barometer stands at 30 inches. £ln evexy jear, eren in the same neighbourhood, a week's difference may be observed in tlie giain harvests, owing to early or late
