Report upon the Meteorological Observations, $>c. 399 



In the beginning of May the weather was cool for the 

 season, the thermometer, during the first fortnight, rarely 

 indicating more than 64° at noon, and being as low as 48° and 

 50°. At this time a good deal of rain fell, but towards the 

 end of the month the weather became fine, and the thermo- 

 meter at one time rose as high as 76°. The mean degree of 

 moisture was .840, and the least degree of moisture .427. 

 The amount of rain was 2.90 inches, and the prevailing 

 winds were southerly, having been in that quarter 14 days 

 out of 31. 



In June the weather had become much warmer, and was 

 upon the whole very fine ; the thermometer was frequently 

 as high as 78°, and once 81°, at noon, and at night seldom 

 lower than from 57° to 63°, so that the nights of this month 

 were as warm as the greater part of the days of May. The 

 lowest point to which the thermometer fell was 46° on the 

 morning of the 22nd. Very little rain fell except in the be- 

 ginning of the month, in consequence of which the atmo- 

 sphere became so dry that the mean degree of moisture was 

 not higher than .792, while it was observed, on one occasion, 

 as low as .389, and towards the end of the month the dew 

 point at noon was frequently much higher than 20° ; on one 

 occasion it was observed as high as 28°. The wind was not 

 in the north for a single day, and in the N. E. only 3 days. 



July was remarkably hot and dry. During the whole 

 month there fell only .05 inch of rain. The mean humidity 

 of the atmosphere was not so high as that of June by .067, 

 amounting on the whole to only .725 ; but no single observa- 

 tion during the month indicated a much lower degree of 

 moisture than was noticed in June, The thennometer was
