616 METEOROLOGICAL OBSERVATIONS. 



The Temperature. 



The temperature was lower in winter at the Astronomical 

 Observatory and in the outer channel than at the Meteorological 

 Observatory. 



The following notes, as to the amount of daylight, are added to 

 the tables : — 



" Nov. 10. Thermometers could not be read without a lantern. 



" Nov. 22. Barely able to read at midday. 



" Jan. 19. Able to read large type by illumination from southern 

 sky. 



"Jan. 22, 1854. Thermometer read at 12 o'clock without a 

 lantern. 



"April 19. The sun was refracted above the horizon at mid- 

 night. 



" May 20. Sun's power felt. Black tarpaulin sinks on the snow 

 about 2 inches in a day. 



" Nov. 19, 1854. Could not read Parry's type at noon. 



" Nov. 29. Mercury congealed at —42° -7, and melts at —38°. 



" Rise of temperature during fall of snow ; maximum fall of 

 snow during the period of new moon, as seen in tables ; minima 

 of cold near the time of new moon. 



" Superior maximum of Dec. 27th to Jan. 1st, 1853-4, during 

 which time it snowed 44 hours." 



This should be taken in connexion with the direction of wind, 

 which on Dec. 28th blew a gale from S.E. (magnetic), during 

 which the temperature rose nearly 23° F. in five hours, from 

 — 6°-4 F. at midnight to +16° -5 at 5 a.m. 



During December 1853 there are clear indications of a rise of 

 temperature accompanying S.E. wind, and so often does this occur 

 that the following remark is appended to the table of force of 

 wind, p. Q>C) : — " The connexion of the rise of temperature with 

 " the wind is embarrassing." (Sm. Con., vol. ii., p. 10.) 



Under table of temperatures, Dec. 1st, is note, " Temperature 

 " falling 21°" 8 in eight hours." On referring to the table of wind 

 it is found that this is during a wind from the N.E., followed by a 

 calm. With the S. and S.E. wind following, there is a rise of 

 temperature. So again on Dec. 4th and 5th. 



Agam, on Feb. 7th, 1854, there is a rise of temperature of 

 35° F. in 12 hours, during a calm of four hours, followed by wind 

 from E. and S. during eight hours, during which thermometer 

 rose to 20°-5F. 



To this there is the remark : — " These warm changes are very 

 " trying to the health, and curious in their relation to the ivinds.'' 



On the next day one hour's north wind sent the temperature 

 down 10°, but three hours after the wind from the S.E. sent it 

 up 10°. 



" March 9. Between 1 a.m. and 2 a.m. the temperatare rose 

 12° '5. At the close of the watch there was a fresh breeze from 

 the eastward. 



"March 22. Temperature rises ll°'l betvveen 6 and 7 a.m. 

 Wind S.E."
