A TABLE, 
f_To face page 
Of the firogrest of Vegetation in Pennsylvania, compared with that of some of the famous Wine Countries of Europe. And also exhibiting the results of various Meteorological observations. 
$y The variety of Grape-vine particularly noticed herein, is the Munier, commonly called Miller's Burgundy. It was cultivated at Spring-Mill, 11 3-4 miles in a direct line, N. W. by N. from the city of Philadelphia, in 
an open country exposure; and, of course, later in every stage of its vegetative progress, than if growing in a sheltered and warmer situation.

The most intense cold which we have had in Pennsylvania, between the first day of January 1787, 
and the first of February 1806, according to a regular series of observations made at S/iring-Mill, every 
day at sun-rise, and at two o'clock in the afternoon, the thermometer in the open air, sufficiently shaded, 
about five feet from the surface of the ground, and out of the way of any extra reflexion of the sun's rays, 
occasioned by walls, pavements, £cc. happened on the 2d of February 1789; the mercury having fallen 
that day, to 17-j 5 ^ degrees below zero or of Fahrenheit; and the greatest heat during that period was HI 
July 1793, when the mercury rose to 104-,^ degrees. July is, generally, our hotest month; and our great- 
est degree of heat, on an average of several years, may be estimated at about 99^. January is, usually, 
our coldest month, in the course of which, we may always expect a degree of cold, equal to 1 ,% below 0. 
Atlentive observations, at the above place, from the beginning of the year 1787, to the end of the year 1800, have given as a medium for one year, 4 days of Aurora Borcalis, 16 of thunder, 7 of tempestuous 
weather, 16 of snow, 249 of fair settled weather, and 73 of rain; and the average quantity of water which had fallen annually, to be 39 inches, 9 lines, and \% of a line, English measure. Our atmosphere is 
generally clear, and seldom so overcast, as to obstruct the ray? 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 T 6 ^ below 0; the greatest heat, on the 4th of May and 9th of July, being on each of these days 95 degrees; 
anil the medium temperature of the whole year, resulting from observations made on every day thereof, was 55 T 2 g-. 
In the year 1805, on the 12th and 25th of January, the mercury fell to 2 T % below 0; on the 2d and 22d of August, it rose to 100-^; and the medium temperature of the whole year, was 57 T %. It is ob- 
servable that the medium heat of each of these two years, was much greater than of any year from 1787 to 1800, inclusive. 
In Paris, the greatest summer heat is, generally, between 92 T 7 ^ and 95 degrees; the most intense cold, between 9-^ and 5; and the medium heat of the whole year, as established on the result of 70 years 
observations, 51-^. But in the year 1716 the mercury had fallen thereto 3^ below 0; in the year 1720, it rose to 104, and in 1743, to 99^. The coldest month at that place, is January, and the hottest August. 
.. At Hoorn, in Holland, in the year 1763, the mercury had fallen to 8 degrees, which is marked on some of the Dutch thermometers, 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, 
or running waters, freeze at 20 T 7 ^; cider and vinegar at 1 1^, and unadulterated wine at 5 degrees. The medium temperature marked onBotanical thermometers, as best adapted for the Pine-Apple, is 73 1 6 - B , 
for Melon-beds 69^, and for an Orangery 57 T 9 5 . 
The constant temperature of the cellar of the Observatory at Paris, is 54-^; which is generally considered to be the same, in every part of the globe, at the depth of about 400 feet beneath the surface. The 
most salutary temperature of the sick or patient's room, is thought to be 72 T 2 5 . The heat of the human blood, in the opinion of the Faculty of Medicine at Paris, is 99-j%: on the English thermometers, it is 
marked 98; and on several thermometers made in Holland and other places in the north of Europe, 96. Heat of Hen's incubation 106^. Fever heat 112. Rain or distilled water boils at 2 12 degrees, when the 
mercury m the barometer stands at 30 inches.
