Address to the Lincolnshive Naturalists’ Union. * 165 
The character of this habitat shows that search should be 
made on similar tracts of common lands, as Scotter, Brumby, 
Crosby and Risby Warrens, and a further examination of this 
Scunthorpe locality at other periods of the year, especially in the 
spring, would yield further results of interest and value. 
An account of the insect-fauna of this pond, and aiso of the 
microscopic life, would also be very desirable, and no doubt our 
good friend Dr. Wallace will be able to enumerate the water 
beetles, the search for which has resulted in so good a find for 
the conchologists. 
There is one species yet to be found of the three I mentioned 
as requiring confirmation, but this year we have not had the 
opportunity of searching Linwood Warren in the hope of 
finding Limax tenellus—a task reserved for next or a future year. 
But as our work goes forward it follows that the more 
difficult it is to add to a long list. And a long list it is, as North 
Lincolnshire figures in the Census of British Mollusca this year 
as the area from which more species have been authenti- 
cated than from any other county in the British Isles. 
Of late I have been looking into the Bibliography of 
Lincolnshire natural history, and although it is inevitably a dry 
subject, it cannot fail to be of some value to take stock of what 
our predecessors have done, so that good work in the past may 
not be lost sight of. 
I will pass lightly over the subjects in which the most work 
has been done, and address myself more particularly to what we 
may find to be the most neglected groups. 
In regard to Physiography, I will only refer to Christopher 
Merret’s Table of the Washes in Lincolnshire—that is, Fossdyke 
and Crosskeys—published in the Philosophical Transactions in 
1696, as among the earliest—Merret being a contemporary of 
Lister. 
Previously to this, in 1684, Dr. Lister published his scheme 
of sands and clays in the North of England, particularly 
Lincolnshire and Yorkshire, which is important as being
