. made at Cambridge. 79 
eonfused sheet of cirrus broke out into cirrocumulus of 
small and ill-defined nubicule, in some places spongelike 
and porous. In the evening was much cirrus coloured 
with rich crimson by the sun in different places all around, 
but particularly the west. hese cirri in the west were 
more striated and approaching to carostratus; in other 
places they were confused. . 
June 3.—Cooler than yesterday, at times heavy clouds 
threatening rain czmzdus in the intervals, with cirrus con- 
fused and rainlike aloft, breaking out into small-grained 
flowery cirrocumulus, into windrows, &c. The night be- 
came clouded. Therm. 11 P.M. 55°. 
June 4.—Clouds often, threaten rain in the morning; 
cirrus this day confused and various broke out frequently 
into cirrocumulus ; in the evening below flimsy cirrocumuls 
hung pendulous flocculi refracting first a bright copper-co- 
Joured light, which as it grew darker passed through fine 
red to lake colour, orange haze. Therm. 11 P.M. 58°. 
June 5.—Cold cloudy day, with occasional small rain, 
and north wind. Therm. 11 P.M. 52°. 
June 6.—Cool and cloudy with a little small rain. Wind 
northerly ; clearer at night again. Therm. 11 P.M. 46°. 
Late by moon-light I could discern a light flimsy kind of 
cirri aloft, and that in some places they were disposed in 
rows, , 
June 7.—Clouded in the morning; afterwards it became 
a fine clear day, with a little flimsy cirrus in the sky in the 
evening. The sun set very clear, with a reddish horizon, 
and faint lines of cirrosératus in it. Therm. 11 P.M, 48°. 
June 8.—Clouded morning, clear day and night. Some 
heavy clouds however in the course of the afternoon: haze 
in the west of a brownish red. Therm. 11 P.M. 49°, 
June 9.—Clouded in the morning, afterwards fair; the 
evening was warm, with a good deal of cloud, though 
sunny intervals and calm air. The clouds were mixed in- 
definite cumuli, flimsy cirrocumuli, and cirrus. I noticed 
about sunset the remarkable blue appearance of a dark 
cloud in the west, it was a sort of sheet-like exmulostratus. 
Therm. at midnight 60°. 
June 10.—Very fine day; cumuli, cirri, &c.; fine clear 
moonlight night. 
N.B.—In future I shall endeavour to give a journal of 
the Thermometer, Barometer, &c, with these observations.
