REPORT OF THE 
29*784, September being highest with 30*206, followed by 
June with 30*122. The extreme range of pressure was 2*147 
inches as compared with 2*117 inches in 1905, and 2*041 inches 
in 1904 ; the highest reading being taken on April 9th, 30*742 
inches at 9 a.m., and the lowest on February 10th, 28*595 
inches at 9 p.m. The barometric curves produced by our self¬ 
registering Barograph are very interesting, and are preserved 
for inspection. 
Rain or Snow (0*005 inches or more) fell on 199 days, 28 
more than in 1905, and 19 fewer than in 1904, the total rain¬ 
fall for the year being 32*76 inches as compared with 20*68 
inches for 1905 and 20*82 inches for 1904. This is still below 
the average for the last 64 years—24'5 inches. The wettest 
months of the year were October, November and January, 
their totals being 4*70, 2*83 and 2*82 inches respectively ; 
whilst September, July and April produced 0*48, 0*92 and 1*02 
inches respectively. 
The cumulative totals for the wettest months since 1841 are 
now October 178*58 inches, August ijj‘02 inches, and July 
164*52 inches ; August thus losing its place as wettest month. 
The heaviest rainfall occurred on June 23rd—*94 inch. 
Observations of the winds show that on no day during 1906 
did the wind blow with the force of a “ gale,” while the chief 
air-currents were W. (127). S.W. (66), N.W. (65), E. (45) ; 
5 days being “ calm ” as against 6 in 1905. 
Days of “ clear sky” numbered 42 as against 38 the year 
before, “ overcast " were 113 as against 117, and there were 
13 thunderstorms during the year as against 8. 
There was a little improvement in respect of bright sunshine, 
which reached the satisfactory total of 1384*3 hours or 31 °/ 0 
The Observatory.— As dry rot had been for some time 
invading the vrnoden floor cf the lower or transit room, render¬ 
ing it very unsafe for observers, it was decided to have a new 
floor laid down. This was completed just before the visit of 
the British Association, but it should be pointed out that if no 
ventilating bricks or apertures are put in the wall below the 
floor line to give air to the space between the ground and the 
new floor, the latter will very soon go the way of the old one.
