"jounuU*May!';?«:^o'!'] PROCEEDINGS OF SOCIETIES. 271 



Committee shall suggest rules for its future government : the meetings 

 to be lield on the foui-tli Thursday in each month, at eight o'clock, the 

 chair to be taken by the President, or, in his absence, by a member of 

 the Committee. After the transaction of the ordinary and special 

 business of the evening, the meeting shall resolve itself into a conver- 

 sazione, at which slides illustrative of the subject of the meeting shall 

 have precedence of other objects of interest and novelty. Before 

 separating the subject of the next meeting shall be announced. On 

 the motion of Mr, Hazlewood, seconded by Mr. Wonfor, it was re- 

 solved " That the Committee's report be received, approved, entered 

 on the minutes, and acted upon," the effect of which is to establish a 

 Microscoi^ical Section, and to make the meetings of the Society twice 

 instead of once a mouth, the first for general subjects of natural 

 history, the second for the microscope in relation to natural history. 



The meeting then became general, when a paper by Mr. Clifton 

 Ward, F.G.S., " A Sketch of the Geological History of England, so 

 far as it is at present known," was read by Mr. Wonfor, Honorary 

 Secretary, in which, from the earliest dawn of the Cambrian period to 

 the present day, the changes brought about by submersion, deposition, 

 elevation, denudation, &c., together with an account of the animal and 

 vegetable types of the various periods, were graphically described, 

 while the amount of land above water in England, at the different 

 periods, was represented by a series of fifteen charts. 



It was announced that the Bryological Flora of the coimty of 

 Sussex would shortly be ready for distribution, the Society having 

 determined to publish it at once, instead of waiting until the issue of 

 the annual report.
