432 REPORT—18638. 
promising success, wefcame down with the view of again falling into the 
east wind, supposing it still to be prevalent. We met the north wind again 
at about 5000 feet, and the east wind at exactly the same height, viz. 2400 
feet, at which we lost it on ascending. We descended to within 1000 feet 
of the earth and were near Worthing, at about 5 miles from the coast; we 
then ascended to 2700 feet, found ourselves moving towards the coast, and 
within the influence of a north wind; evidently, therefore, if we wished 
to continue our journey we must keep below 2400 feet, otherwise we 
should be blown out to sea. When again at the height of 2400 feet we 
turned to move parallel to the coast, being at this time over Arundel. Sheep 
in the fields were evidently very frightened, and they huddled together. We 
now descended to 800 feet, and thus journeyed at heights varying from 
800 to 1600 feet; villagers frequently shouting to us to come down, and 
now and then answering our questions as to the locality we were in. The 
cheering ery of children was frequently heard above other sounds. Geese, 
cackling and frightened, scuttled off to their farms. Pheasants crowed as 
they were going to roost; and as we approached the end of our journey packs 
of dogs barked in the wildest state of excitement at the balloon. 
Thus journeying, all motion seemed transferred to the landscape itself, 
which appeared when looking one way to be rising and coming toward us, 
and when looking the other sinking and receding from us. It was charmingly 
varied with parks, mansions, white roads, and in fact all the constituents of 
a rural scene of extremely beautiful character. The place of descent was 
Goodwood Park, the seat of the Duke of Richmond. 
Ascent from the Crystal Palace, July 21.—The weather on this day was 
bad, the sky overcast and rainy. Although in every respect a thoroughly 
bad day, it was well suited to investigate, if possible, some points concerning 
the formation of rain in the clouds themselves; to determine why a much 
larger amount of rain is collected in a gauge near the surface of the earth, 
than in one placed at an elevation in the same locality ; whether during rain 
the air is saturated completely, or if not, to what extent; to discover the 
regulating causes of a rainfall sometimes occurring in large drops, at others 
in minute particles. 
So long back as the years 1842 and 1843 I made many experiments in 
order to ascertain why so great a difference in volume was found to exist 
in the water collected at lower stations as compared with that collected at 
higher. The experiments which yielded the best results were those in relation 
to temperature. I always found that when the rain was warm, with respect 
to the temperature of the air at the time, no difference existed in the quan- 
tities of rain collected at different heights; but when the temperature of the 
rain was lower than the temperature of the air, a considerable difference 
always existed. 
From this circumstance, it would appear probable that the difference in 
the quantities of rain collected at different heights is owing (at least in part) 
to the great condensation of the vapour in the lower atmosphere, through 
being in contact with the relatively cold rain. 
It was also desirable to confirm, or otherwise, Mr. Green’s deductions 
this gentleman believing that, whenever a fall of rain happens from an over- 
cast sky, there will invariably be found to exist another stratum of cloud at a 
certain elevation above the first. We left the earth at 4" 52™ p.m., and in 10 
seconds had ascended into the mist; in 20 seconds to a level with the clouds, 
but not through them. At the height of 1200 feet we passed out of this rain 
and overlooked a range of surrounding clouds, so dazzlingly white that it was 
with difficulty I could read the instruments furnished with ivory scales, At the
