REMARKS. 



Tenth Month, 27. Misty and overcast a. m. 

 p. m. the Barometer descended at the rate of a tenth of an 

 inch per hour, the wind increasing in proportion, with much 

 rain, the clouds sweeping the earth. The evening was very- 

 tempestuous j before midnight the Barometer had risen again 

 and the weather was moderate. Many large trees were blown 

 down. 28. a. m. hoar frost rather misty. At sunset, the sky 

 exhibited a fine collection of coloured clouds, in the modifica- 

 tions Nimbus and Cirrus, with broad parallel bands of red in 

 the haze above them. 28. Fair and calm. 30. Cirrostratus and 

 Cumulus : the sky again beautifully coloured. 



Eleventh Month. I. Cloudy. 2. a. m. wet. 5. Fine day. 

 6. 8, 9, 10, 11. Chiefly misty or cloudy, with hoar frost, and 

 some very thick local fogs. 11. Overcast, a. m. l*ie Cirrostra- 

 tus prevails, and sounds travel with the wind to an unusual 

 distance : we hear the rattling of the carriages on the pavement 

 in London through a direct mean distance of five miles. This 

 phenomenon is to be attributed to a thick continuous sheet of 

 haze in the air above us which acts as a sounding board. 12. 

 Rain through the day. 13. Misty : rain : sounds are again 

 distinctly heard from the city. 15. Fair : a Stratus at night. 10'. 

 Overcast ; with an easterly gale. 18. Wet stormy day, night 

 clear and calm. 20. Misty, much rime on the trees, which 

 came off about noon in showers of ice. At 1 1 a. m. a perfect 

 but colourless how in the mist: near 4 p.m. there was a shower, 

 in which the rainbow shewed its proper colours. 22. Clear : the 

 ground just sprinkled with hail balls. 23. a. m. misty rime. p. 

 m, clearer, thaw in the night. 24. Clear morning.
