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.

The PLANTS, indigenous to this district, are very numerous. From a list

of several hundreds which are to be found in the neighbourhood, the

following interesting ones are selected.

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 a

singular blue pulverulent mineral, which is a carbonate of iron

containing some earthy impurities, in a valley at Salmonby; and a

stalactitic oxide of iron in the ferruginous gravel; comprise all the

varieties which have yet been found.
