3rd to 8tli — steady at 30"30 inches. The lowest reading was 

 29'60 inches on the 16th. 



Although there was a considerable amount of sunshine, the 

 maximum temperature in the shade did not reach any notable 

 point, 70° being the highest registered — a very much lower 

 figure than usual for Jvme. The average masimimi temperature 

 was 60°, and the average minimum 47°. In June, 1902, these 

 figures were 58° and 47° respectively. 



The rainfall was also low, only 1"53 inches being registered. 

 The heaviest fall for 24 hours was 0'73 inch, noted on the 28th. 

 There were 20 diy days. 



Notwithstanding the amount of bright sunshine, the counter- 

 acting effect of the easterly winds proved a serious check to 

 the tender growth of plants, consequently the development of 

 leaf and shoot was slower than usually is the case at this period 

 of the year. Arboreal vegetation, however, made fair headway, 

 and made a good average in size of leaf and shoot. 



July, — During the first week the weather was mild and 

 somewhat showery. The second week was drier, with some 

 fine bright days. A change of a disagi'eeable nature set in on 

 the 15th, and the heavy rainfall of the following days was a 

 source of fear and disappointment to the many who were look- 

 ing forward to a period of fine weather for the annual holidays 

 at Glasgow Fair. The exceptionally heavy rain and chilly 

 easterly winds made the atmospheric conditions extremely un- 

 pleasant. The week following was, on the whole, fine and dry. 

 It was more showery afterwards, and a heavy thunderstorm 

 occurred on the 27th. 



The barometric readings show that the atmospheric pressure 

 was somewhat irregular, though not of a wide range. The 

 highest readings were 30' 14 inches on the 9th and 30" 10 inches 

 on the 10th and 11th; the lowest, 29'40 inches on the I7th and 

 29-45 inches on the 29th. 



The temperature was again low for this month. Only on one 

 day (the 12th) was the maximum in shade at 70°. The average 

 maximum temperature was 62° and the average minimum 50°, 

 against 61° and 47° for July, 1902, in which year the maximiun 

 thermometer was only above 60° on fourteen occasions, against 

 twenty- two times for month and year under notice.
