8. Velocity cf' Fluids. — It appears from the experiments of 
M. Lehot, that the adhesion of water and alcohol to glass di- 
minishes in proportion as tlie temperature is increased ; and 
that under the same pressure, a jet of water which escapes by a 
vertical capillaiy tube will rise higher as the temperature be- 
comes greater. — BibL Univers. Mars 1820, p. ^225. 
METEOllOLOGY. i 
9. J^iraselene seen at Liverpool. — Tiiis rare meteor was 
observed by Hr Trajili at Xiiyerpool, on the everting of the 80th 
of March 1820, about 10 o’clock. The moon was then about 
85° ajboye the soutliern horizon. The atmosphere was nearly 
calm, but rather cloudy, and obscured by a slight haze. 4- 
wide halo, faintly exhibiting the prismatic colours, was described 
round the moon as a centre, and had a small portion of its cir- 
cumference cut off by the horizon. This circular band was in- 
tersected by two small segments of a larger circle, which, if 
completed, would have passed through the moon, and parallel 
to the horizon. These segments were of a paler colour than the 
hrst mentioned circle. At the points of intersection appeared 
two pretty well defined luminous discs, equalling the moon in 
size, but less brilliant. The western paraselene had a tail or 
c’oraa, which was directed from the moon. The coma of the 
eastern paraselene was much less distinctly marked, and was 
soon lost in the adjoining segment of the larger circle How 
long the meteor lasted is not ascertained. Dr Traill’s atten- 
tion was directed by a friend to an unusual appearance in the 
sky about 10 o’clock ; and then these phenomena were visible 
to him and several other individuals for above half an hour. 
The whole gradually faded away. The accompanying figure, 
Plate IX. Fig. 11. will give a tolerable idea of the meteor. 
10. Meteoric Stones in the Form of Leaves. — -A meteoric 
substance like black paper is said to have fallen near Randen in 
Courland, on the 81st January 1686. This fact led M. Von 
Grotthus to recognise it in a substance in his owm museum, 
which had a label attached to it, stating it to be of meteoric ori- 
gin. It is a mass of black leaves resembling burnt paper ; but 
it is harder, brittle, and coheres together. It has been found 
to consist of silica, magnesia, iron, some nickel, and traces of
