34 
also, just exceeded 50°. Still on no day did the mean of 
maxima and minima reach 50°: this has only occurred on 
March 18th. And yet some of the maxima during the opening- 
week were extraordinary, the 71‘3 of the 1st not having been 
equalled at so early a date, whilst nothing above 70° has been 
recorded since 1875, The other records above 70° are in 1852 
(72°), 1859 (73°), 1864 (71*°;, 1869 (76°), 1870 (75°), and 1874 
(75°). In many years 70° is not reached before June. 67-6° 
(in 1884) is the highest March record before this year. 
As the minimum on April 1st was 27° ( 22 ° on the grass) 
there was a range of 44°, which has probably been rarely 
equalled. The cause was the almost entire absence of wind, 
the intensely dry air and the clear skies. At mid-day differences 
between the wet and dry bulb of 14° to 16° were recorded at 
about this date, which gives a relative humidity of under 
35 per cent. 
After the 12th the horizon was unusually clear, so that the 
West Riding Hills were visible from Feversham Terrace on 
\2 days, which is the highest record during the 10 years of 
these observations. 
Solar Halos were observed 10 times, lunar halos twice, mock 
suns three times. The halo and mock suns on the 30th were of 
extraordinary brilliancy and endurance, whilst on the night of 
May 1st the very rare phenomenon of a mock moon was noted, 
at the same time as an Aurora (10-45 - 11 p.m.). The Aurora 
on the 25th was very fine, perhaps the finest witnessed here 
since 1882. Streamers, although intermittent, were bright and 
extensive, and the crimson shades above Yenus at times very 
intense. The maximum effect was at 9-45 p.m., but it was still 
visible after 12. 
Bright sunshine reached the unusual April total of 179 hours, 
only exceeded during the previous eleven years of observations 
by the 182 hours of 1887. These values are both 50 per cent, 
above the average. In 1885 we had only 87 hours.
