REMARKS. 



Tirst Month. — IS. Miirh wind last night : very fine day : Cumulus and Cirrostru- 

 tus. 14. a.m. Somewhat cloudy. 15. Overcast «ith Cirrostratus : lijht breeze. 

 There beiii*; no evaporation to-day, the surface of the snow is a liitle w.-irmer than 

 the air. 16. Overcast: a slight thaw, from the warmth of the earth: at evening 

 snow and frii~t ag;ain, 17. A clear day: Cirrtis and Ctrrostrtilui in the eveiilnof, 

 with a inw A/mAi/x. or two, forming. At sun-set, the temp, being 18*, there was 

 a bed cf haze in the 1^. like that ivbich accompanies the fall of dew, but much more 

 dense, and singularly coloured. It was c'.iefly of an indigo blue, but parsed 

 below iato opake uhite, and above into a faint red, more transparent. 18 A 

 inowy morning: small snow and fleet through the day. 19. A snowy day. 20. 

 Snow : the wind strong at N.K. 21. AtSa.m. beginning to snow again. In the 

 drifts the snow is many feet deep. This day pro\erl fine and calm: the wind, at 

 limes, S.AV. 22. A little snow in the morning :.4iiie day: strong breeze, with 

 ■various clouds. 23. Snow, morning and evening. There was a fine exhibition of 

 clouds : as Cumuli, well formed, but with little colour; the superior modifica- 

 tions, iiclud ng the Cirrocumulus \ and several distinct Nimbi. 24. The sky 99 

 yesterday' : snow, a. m. the wind brisk : aboii: two p^m, a squall, » ith plenty of 

 snow. S5. a. m. A fine elevated grey sky : tnen. Cirrus and Ciirosfralus, the w ind 

 veeringby N. to VV. It has had lately much tendency to this quarter at night. 

 26. A h>llow wind at S.W. : snow, followed by small rain. 27. A misty thaw : 

 alittle nin at intervals: wind and rain in the night. 28. a. m. Misty, with rain; 

 the wine W. : after this a little snow : then fair, and frosty after sun-set. 29. 

 Stormy : the wind S. E. with snow early: then steady rain, followed by more 

 mow. Ihe minimum of pressure occurred after six p. m. It was not confined to 

 a small sjace c f time. As the barometer began lo ri^e, the wind came round Uy 

 S.W. to i.W. and bl?w with grcr.t violence till near morning. 30. A fine day: 

 strong breze, with clouds : at sun-set a sprinkling of opake hail. 31. lair day : 

 but at seen p. m. a sudden heavy snow shower. 



Second Month. — 2. Hoarfrost. 3. Hoarfrost. A very fine sunny day, followed 

 by bright moonlight. A thermometer, at an intermediate height, between tfee 

 standard )ne and that on the snow, gave 14" as the minimum. The latter instru- 

 ment at e^ht a. m. had risen onlj to 4*, aud was thickly covered with rime, although 

 at night tfere had been an appearance of strong evaporation. 4. Sunshine, and fair 

 uight. Aout nine p.m. a colourless halo, of the largest diameter, with Cirrus 

 clouds, it half past ten a small coloured halo, with Cirrostratus. The temp, on 

 the snowbeing 12°, the wind \V. a breeze, I now exposed, in a metallic dish, 

 close to tfe thermometer, 2600 grains of snow (which had become hard by freezing) 

 in two orthree masses. At half past eight, or in ten hours, the temp, having risen 

 to 28% it ad lost 27 grains in weight. 5. Crimson sky at sun-rise : hollow wind : 

 mow andleet. 6. A gale from S.W. with showers of rain : at evening it cleared 

 up, and bDw from N.W. 7 to 11. Cirrostratus a,nd Cirrocumulus : red skj at sun- 

 rise: gale of wind, and a few showers.

the conclusion Southerly. 



Barometer : greatest heigiit 3015 inches; 



Least 28-22 inches ; 



Mean of the period 29*59 1 inches. 



thermometer : Greatest height 50* 



I . Least 8" 



On the surface of the snow 2° 



aiean of the period 31 -SI"

Some obiiirvations on the present winter, compared with the last severe one (of 

 J794 — 5), 01 the origin of the fogs which prevailed in each, and on the recent great 

 depression cf the barometer, must be deferred to neit communication.
