ducing an unlimited number of their friends. ‘The Subscri- 
bers of ten guineas, will, in addition to this privilege, have the 
power of attending the various meetings of the Society, of 
bringing a friend with them, and of making use of the Library, 
now containing a considerable number of books, and which 
continues gradually to increase, both by donations from Mem- 
bers and friends, and by purchases. To a Subscriber of twenty 
guineas, or upwards, a vote in all proceedings, and every 
privilege enjoyed by Members is allowed in the fullest extent. 
In addition to the Ordinary Members of this Society, by whom 
the business is conducted, and who are bound by rule to read 
in rotation at the meetings, a class of Members has for some 
time existed, called Visiting Members, who are exempt from 
any of the labours to which the others are subject. These 
formerly paid a higher subscription, but they are now admitted 
at the same rate as the Ordinary Members, £1 1s. per annum, 
becoming a very numerous class. Since the commencement 
of this Society, a considerable Museum has been collected ; 
some progress in the formation of a Library has been made, 
and 222 papers have been read at its various meetings. It is 
intended thatthe regular meetings of the Society should be 
held, as they have always been, once each fortnight, on Wed- 
nesday evening, at eight o’clock. To these no person will be 
admitted, except Members, Subscribers of not less than ten 
guineas, and gentlemen introduced by them, for a large au- 
dience is unsuited, by its very nature, to the calm and deliberate 
investigation essential to natural science. But the Members, 
in order to extend a taste for those pursuits, in which they are 
themselves engaged, have agreed to give occasional popular 
lectures on various subjects, and to give increased powers of 
introduction on those cccasions, both to Members, and ten 
guinea Subscribers, according to the number which their rooms 
can conveniently accommodate; and they expect, at these 
meetings, to be honoured with the presence of ladies as well 
as of gentlemen. The first of these Lectures will be delivered 
on Wednesday evening, the 30th November, 1831, by Professor 
Stevelly, on the Winds. The collections of objects of Na-
