scription of two guineas ; and the last, subscribers annually of one 

 guinea, having- no interest in the property of the Society, or voice in 

 its deliberations. Meetings are held the first and third Fridays in 

 every month, from November to May, inclusive, for the reading of 

 papers and essays by the members, to which each has the power of 

 admitting a stranger. In addition there are annually two or three courses 

 of lectures, by some public lecturer of eminence, amongst whom there 

 have been Dr Dalton, Professor Grant, Professor Phillips, James 

 Montgomery, Esq. Edward Taylor, Esq. &c. From the commence- 

 ment of the Society 240 papers have been read on various branches 

 of literature and science. 



The private collections in Leeds are, first, a valuable museum of 

 Natural History, &c. in Commercial Street, the property of Mr John 

 Calvert, admission Is.; — very extensive collections of shells, corals, 

 and minerals, belonging to Miss Banks and Miss Rhodes ; — the col- 

 lection of comparative and human anatomy, belonging to the Leeds 

 School of Medicine, and a collection of comparative anatomy and 

 Natural History, especially of the Invertebrata, belonging to Mr 

 Teale." H. D. 



The well " got-up" volume before us is the first part of a proposed se- 

 ries of Transactions, and it gives us pleasure to know that the circum- 

 stances of the Society are now so prosperous as to enable it to publish a

 introduction to the volume, we perceive that the leaning of the great 

 proportion of its members is more towards literary pursuits than the 

 study of zoology and botany. Nevertheless, there is a fair propor- 

 tion of papers devoted to interesting subjects in both these branches. 

 We have now printed " on the Bed of the Mississippi, by the late John 

 Luccock, Esq., read in November 1824, prepared from a personal 

 knowledge of the course of the river obtained in a lengthened journey 

 made in the previous year." An interesting paper in favour of the 

 theory of the gradual corrosion or wearing of the barriers which stem 

 the great common lakes, with the author's opinion of the former pro- 

 bable extent of water on the surface of the now existing North Ame- 

 rican continent.-™ — On the varieties of water, by William West, 



read November 1829. A description of the internal structure of 



various Limaces, found in the neighbourhood of Leeds, by Thomas 

 Nunneley, read November 1834 : illustrated by seven plates lightly 



but distinctly executed. Abstract of a notice of certain Roman 



Coin Moulds, by John Hey. On the Anatomy of Actmea cori-
