when the re-arrangement — the rebound — the back stroke 
occurs, some important action must take place in the organic 
forces, such as the nervous and the muscular. Cases are 
quoted in illustration, and the Author then remarks that 
from long series of observations it would appear that there 
is an intimate connexion between hail and snow showers, 
stormy weather, atmospheric electricity, and certain forms of 
disease; and he ventures to add that hail and snow are 
formed under the influence of opposite electrical conditions, 
and concludes by suggesting the means of putting this 
opinion to the test of experiment. 
MICROSCOPICAL SECTION. 
November 19th, 1860. 
A Letter was read from Mr. R. D. Darbishire, relative to 
the deposits from the raised sea bottom found at Capell 
Backen, Uddevalla, near Gottenburg, in Sweden. He 
observes that “the hill side from a height of about fifty feet 
above the level of the sea to that of about two hundred and 
thirty feet, consists of layers of fossil shells, varying from ten 
to thirty feet thick, alternating with beds of more or less 
coarse gravel and clayey sand.” Mr. Darbishire contributed, 
for the use of the Members, a parcel of washings from shells, 
and a box containing dry sieved soil for microscopical 
examination.
