This mean heat of 50 degrees in 
springs and range of 99 degrees, is 
an additional proof that the interior 
of this continent is warmer than 
the coast and has a lesser range of 
variation, an usual concomitant ef- 
fect. Since Portsmouth in New 
Hampshire on the Atlantic ocean 
and the same parallel of 43 degrees 
as Rochester, has a mean tempera- 
ture of 44 and range of 110. While 
Detroit in Michigan, still farther- 
west and also near 43 degrees, has 
50§ mean heat, with a range of 1 16. 
It must be added that Rochester 
and Detroit are both much above 
the level of the ocean and ought 
there tore to be colder on a par.* 
Parallel of 43 degrees latitude. 
1. Portsmouth, level of the sea, 
44 degrees mean heat, range of 110 
degrees. 
2. Rochester, 480 feet above the 
sea, 45J mean heat of the air, 50 of 
the springs, range 99* 
3. Detroit, 565 feet above the 
sea, 50| mean heat, range 116? is 
this right? 
It is probable that the increase of 
mean heat and smaller range, is 
gradual all the way from the At- 
lantic to the Pacific ocean; where a 
difference of 12 degrees at least in 
equivalent temperature and range 
is found. There the 52 degree of 
latitude being equal to the 40 de- 
gree, near Philadelphia or as warm. 
The 52 degrees of Europe is also 
equal to the 40 in China, the east- 
ern part of each continent being 
colder. 
But the different years often give 
variable results: thus this year,! 832, 
the winter has been very severe all 
over North America. The river 
Delaware was frozen at Philadel- 
phia from the beginning of Decem- 
ber to the middle of February, 
which had not happened for nearly 
40 years. In Rochester it is stated 
that the winter has been more se- 
vere than for 20 years past in the 
Genesee country. By .compara- 
tive observations made at Albany 
and Rochester iq December last, at 
sunrise, there has been found a 
great difference of many degrees of 
warmth in favour of Rochester, aU 
though it is 480 feet above the sea, 
lat. 43 10 , and Albany at tide water 
in lat. 42 35.

This is an additional complete 
proof that the climate improves in- 
land. 
The Genesee Country of which 
Rochester is the, metropolis, extends 
from Pennsylvania or lat, 42, to 
Lake Ontario in lat. 43 It con- 
tains about 4000 square miles of 
fruitful soil. The staples are wheat, 
averaging 20 bushels to the acre, 
and maize averaging 40 bushels. 
The mean heat of the vegetating 
season is 60 degrees.

Results of the Experiments of 
Recluz on the Fixed Oils . 
This article is one of those of 
practical Sciences, which belong 
at once to many, being connected 
with Agriculture, Gardening, Che- 
mistry, Economy and Materia medi- 
ca; this enhances their value. 
Fixed Oils of Vegetables are of 
the utmost importance and use for 
food, light, cooking, soap,machinery, 
manufactures, md medicines. It 
was very needful to ascertain ex- 
actly what quantity was afforded by 
each- vegetable, so as to know the 
most profitable to cultivate, and 
cheapest to use; this has been done 
by Recluz, a French chemist, and 
Me give here the analysis of his 
labours. 
All the experiments were made 
upon one pound of the substance, or 
7680 grains weight, and the quantity 
of oil afforded is stated in ounees. 
Almonds 7\ ounces. 
Bern p seed 3 1 ounces* 
Cocos 4 ounces. 
Olives 3| ounces* specif# weight 
0915, forms solid soap.
