when the re-arrangement — the rebound — the hack 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.
