NOTES. 



Third Month. — 9. A shower of hail p. m. 11. Hoar frost. 

 15. Frosty morning. 16. Wind very strong from N. E. all 

 day. 17. Cold wind. 20. Snow in the morning, followed 

 by rain. 22. Very wet night : high wind. 25. Snow: the 

 barometer rising rapidly. 26. a. m. Very fine : barometer 

 still rising. 27. a. m. Cloudy; a considerable depression 

 of the barometer, with appearances indicating thunder. 

 Late at night a shower of hail, with lightning. 28. Stormy, 

 with showers. 29. a. m. Windy. At 2 h. 30 m. p. m., the 

 temperature without being 54°, I found the vapour point in 

 a room as high as 51°. In an hour after this it began to rain 

 steadily, and there fell near half an inch depth. 30. Much 

 wind, at intervals changing to E. 31. Stormy from E. and 

 S. E. : cloudy : about 9. p. m. an extensive appearance of 

 light in the clouds to the W. with rapid coruscations passing 

 through them, in the manner of an aurora boiealis. This 

 phenomenon was apparently not more elevated than the 

 clouds which then overspread the sky, and was certainly not 

 produced by the reflection of a light situate below them : 

 it continued 20 or 30 minutes. 



RESULTS. 



Prevailing winds easterly. 



Barometer: highest observation 30*35 inches; lowest 99/ie inches; 

 Mean of the period 29739 inches. 



Thermometer : highest observation 59 ; lowest 24° ; 



Mean of the period 41'5°. 

 Evaporation 191 inches. Rain, &c. 280 inches. 



This, as well as the preceding lunar period, has been un- 

 usually productive of rain : the two afforded six inches and 

 a half in fifty-nine days.
