JULY WEATHER. 



We had a rather larger dose of " July fog " than 

 usual this year, although only two lasted all day, and 

 most days cleared bright and warm after the fogs 

 cleared away, generally about 11 o'clock. 



Foggy mornings and clear cold days, with high 

 barometer, prevailed from the 1st to 9th. when a 

 slight fall to 29'85in. was followed by a slight shower, 

 and the glass again rose with cold frosty weather and 

 thick fogs ; that on 15th lasted all day. During this 

 time the barometer stood almost continuously at 30'45 

 inches. On 16th a thick cloudy sky, and a falling 

 barometer, ushered in a change, and on the 18th there 

 was a steady, long, continued downpour. 1'14 inches 

 of rain, out of a total of 1*27 inches for the month, fell 

 in 30 hours. After this we had again clear, cold, and 

 still weather, and a high barometer tiU 24th, when a 

 very decided change, that seemed to bring us sud- 

 denly from winter to spring. Heavy masses of clouds 

 were driven from N.W. by high and mild Avinds that 

 occasionally descended to the earth's surface, and the 

 barometer steadily fell to 29 '21 inches on 27th, and two 

 light showers fell from clouds that seemed to have 

 parted with their surplus moisture before they reached 

 our district. 



An unsettled barometer and a disturbed sky till the 

 end of the month appear to indicate that we shall have 

 changeable stormy weather for some time to come. 



There has been 10 61 inches of rain since the com- 

 mencement ol the year, to 9*87 inches to same time 

 in 1876 ; 11-53 inches in 1875, and 10*69 inches in 1874. 



ThQ mean of terrestrial radiation was 29 '42°. to 

 26 "90^ last year. Mean temperature in shade, 44 "46'' 

 to 41-53' ; Solar intensity, 100-04" to 94-96 of last July, 

 prove how warm and bright tliis month has been. 



The clouds, 5-90 this year to 5-37 last, was owing to 

 fogs, of which we had 14" to 8 of last July. 



The ozone was almost the same, 7 '62 to 7 '82.
