ment, though the coleopterists, under the leadership of Mr. T. 
Stainforth (Hull) and Dr. Wallace (Grimsby) were more 
fortunate. Conchology had its leaders in Messrs. W. Denison 
Roebuck (Leeds), and J. F. Musham (Selby). 
Mr. J. F. Musham writes :—Attention was given to the 
dykes bordering the route, and to the Blow-Wells, ponds ; 
then to quarries, and woods at the eastern extremity of the 
district. A short visit was also paid to similar ground near 
South Ferriby, which is in a different district (3 S.W. Lincs., 
whereas Barton is 3 N.E.).

FLOWERING PLANTS. 
The Chemistry of the Cuckoo-Flower (Cardamine 
pratensis).—One of the heralds of the gay and jocund spring- 
time this plant undoubtedly is, though it does not worm itself 
into the affections quite so readily as the primrose, and other 
flowers that paint the meadows in the opening of the year. It 
affects wet localities in fields, but, unlike‘its near ally, the water- 
cress, is unable to hold its own as a water plant, it not being 
sufficiently plastic for the purpose. The root-stock is densely 
clothed with fibres without mycorhiza, and there are numerous 
water-conducting tubes in all the plant. On 5th June the dried 
overground parts yielded 1-7 per cent. wax, with a little carotin 
and no fat-oil ; the alcoholic extract was only feebly bitterish, 
and contained a tannoid similar to rutin or luteolin, but no
