Three hundred rock specimens from the Harz, accom- 

 panied bj a German catalogue, which has been translated by 

 one of the members of the Society, * constitute the fourth 

 liberal donation for which the Museum is indebted to Mr. 

 Heiiland ; and one hundred and fifty species of corallines 

 and shells, from the calcaire grassier of Grignon, have been 

 presented to the foreign collection by Mr. Tasburgh. 



Several interesting specimens have been added ^ to those 

 formerly sent from the mountain limestone of Northumber- 

 land, which show that some of the generalizations in which 

 geologists have indulged, respecting the distribution of fossils; 

 are premature. This addition includes, besides patellae and 

 echinal spines, a saurian vertebra, and an impression of a 

 fern analogous to those which occur in the coal-measures. 

 The donor has communicated his observations on the rocks 

 from which these fossils are derived ; and, in correction of a 

 common geological error, states that coal of a good quality, 

 and in great abundance, occurs in the lower part of the 

 limestone series. 



Numerous shells have been contributed from the crag of 

 Norfolk and SuiTolk, ^ and some beautiful crinoidal fossils 

 from the oolite of Gloucestershire. * There has also been 

 placed in the Society's cabinets a specimen of the head of tlie 



' The Rev. J. Kenrick. * By the Rev. C. V. Vernon.
