the 2Gtli July, when 1-4:8 iu. was registered. But there were 

 other two days in the same month Avhen the fall exceeded one 

 inch, viz., the 2ud, in connection with a thunderstorm, and the 

 25th, when the records were I'Oo in. and 1-15 in. These were 

 the only occasions on which the fall exceeded one inch. July wa.s 

 the wettest month in the year, with a total of G-28 in., spread 

 over 21 days ; and the next wettest were August, with 5-73 in., 

 and November, with 5-41 in. These records were considerably 

 above average, and those of March and April were slightly so. 

 The rainfall of all the other mouths was under average, and some 

 of them in a remarkable degree. The driest month was May, in 

 which only <)'21 in., or less than a quarter of an inch, fell. The 

 next was September, with very little more than half an inch, viz., 

 0"56 in., and February had also less than an inch — 0-81 in. In 

 these three months the rainfall amounts to no more than 1-58 in., 

 while the ordinary mean for them is 7-13 in. There were several 

 periods of drought durmg the year. The first was in February. 

 Between the 8th and the 28th of that month, a period of about 

 three weeks, rain fell only ouce, and only to the amount of four- 

 hundredths of an inch. Again, in May and June, there was an 

 extended period beginning with the 1st of May and continuing to 

 about the 25th of June, a period of about eight weeks, during 

 which the rainfall did not exceed 0-48 in. The rainfall for the 

 whole year, 35-03 in., shews a deficiency from the average of the 

 last nine years of about 2 in. 



Hygeometeh. — The mean dry bulb for the year was 4G-G 

 deg., almost exactly the same as the mean annual temperature, 

 which was 4G-7 deg. Mean wet, 44-2 deg., giving for the dew 

 point 41-3 deg., and for the relative humidity 82 — saturation being 

 equal to 100. The only remark to be made upon this is that the 

 mean temperature of the dry bulb is about I deg. under average, 

 corresponding with the similar deficiency in the mean temperature 

 of the year, and that the relative humidity of 82 exhibits a like 

 correspondence with the diminished rainfall, the average of nine 

 years being 83. 



Thunderstoems were not frequent during the year. So far 

 as I have observed, there was one iu April on the 24th, one in 

 May, also on the 24th (which was repeated to some extent on the 

 following day), two in July in the beginning of the month, two in 

 August on the Gth and the 27th, and one in September on the 9th.
