NATURAL HISTORY.

In the department of Natural History, this district possesses but little which is deserving of particular notice. Of birds there are none which can now be considered peculiar to this part, the drainage of the fen lands having entirely banished the great variety of aquatic birds which used, previous to that event, to be found here.

A variety of plants, many of which are of rare occurrence in other parts, are indigenous to this neighbourhood: a list of them is given in the following table.

Minerals occur rarely in this part, and in very small quantities. Lumps of sulphuret of iron in the oolite stratum, earthy oxide of iron and prussiate of iron in a valley at Salmonby, and a stalactitic oxide of iron in the ferruginous gravel, comprise all the varieties which have yet been found.

Although organic remains are to be found in some parts of this district in considerable quantities, yet they do not include many varieties. The following list of those now in the collection of the author, comprises one of almost every species which has yet been found.
