Y-t Meteovologkal Summary for 1822. — Essex, 



tuation must indeed be wretched ; and what ought the country, 

 in contemplation even of its possibility, to do? First, to 

 dispatch directions to the Governors of Canada, Hudson's 

 Bay, and the North West Company, directing them to equip 

 different parties of natives, with proper supplies, to go in search, 

 by the Copper Mine and Mackenzie's Rivers, and other routes, 

 with a secin-ity of being rewarded at any rate, and mimificently 

 in case of success. Secondly, that two or three small vessels 

 be sent in different directions. Thirdly, that Davis's Straits 

 ships be encouraged to sail a fortnight or more before the usual 

 time, and explore the coast before they come to the fishing- 

 ground. These, or any other expedients, should be adopted, 

 ratlier than a single chance be lost of saving these brave men.

SU3IMAUY OF METEOROLOGICAL OBSERVATIONS FOR THE 

 YEAR 1822. ESSEX. 



To the Editors of the Philosophical Magazine. 



Epping,Jan. 7, 182.3. 

 The following Tables present the monthly means as de- 

 duced from an accurate Meteorological journal kept at Ep- 

 ping, latitude 51° 41' 4'2" N., longitude 27^ east of Green- 

 wich, during the year 1822. The observations from which 

 these tables have been constructed were made with good in- 

 struments, and as near the times specified as possible ; the ba- 

 rometer, with the attached thermometer, hangs on the landing 

 place of a first flight of stairs, with the surface of the mercury 

 in the basin twelve feet from the ground, and where neither is 

 affected by any artificial heat; the external thermometer is at 

 a great distance from any building, freely exposed to the air, 

 has a northern aspect, and is not affected by the direct rays of 

 the sun ; its height from the ground is about 4 feet. The 

 rain gauge is in a perfectly exposed situation, and is about 7 

 feet from the surface of the ground. This instrument was sent 

 me by that indefatigable meteorologist, Luke Howard, Esq., 

 and is well adapted to the purpose ; at the same time, great 

 care was taken to measure the water as often as any fell, so as 

 to prevent the least duninution from the effects of evaporation, 

 — a precaution very necessary to be attended to, especial ly du- 

 ring wind, in the spring and summer months. The evapo- 

 rating gauge is about three feet from the ground, has a small 

 roof to prevent the rain falling into it, but, is so placed as to 

 admit of a free circulation of air over the surface of the water 

 intended to show the quantity of evaporation. I find from 

 experiments made at the same time, with evaporators of the 

 like lineal dimensions, that the process of evaporation is so 



liable
