314 LINCOLNSHIRE NATURALISTS AT SLEAFORD, 
another disused pit in the Lincolnshire limestone at South Rauceby. 
Then, retracing our steps to Bullywells, we crossed the Slea and 
examined another pit called ‘Greylees, in an outlier of the same 
formation. In this pit the rubble at the top of the oolite is much 
broken up and contorted, dipping in every direction, and curved 
and folded in an extraordinary manner. ‘The rocks, however, under- 
lying this rubble, are undisturbed, except on the south side, where 
there are signs of an uplift. This may be connected with the uplift 
in the gap through the oolite cliff at Ancaster, which lies a few miles 
off on the west, where the Witham once flowed; and the dis- 
turbance of the rubble may be due to this cause. There is, however, 
in the same field, but at a higher level than this outlier, a bed of 
sand and gravel, which has been partly excavated, and which shows 
signs of strong river action; patches of gravel being intercalated 
with the sand, giving the whole a semi-stratified appearance ; and 
this again may account for the breaking up and disruption of the 
rubble. The matter is well worthy of careful and more prolonged 
study than we were able to give to it. After leaving these pits we 
crossed the line to Grantham, which lies on river gravels, and going 
over a narrow band of the great oolite limestone, and another still 
narrower band of the great oolite clays beyond it, we got on the 
Cornbrash ; and after a look at the beautiful church at Quarrington, 
we continued on this formation till we reached Sleaford, after a very 
pleasant walk. 
Most of the Union’s best botanists were present, and the ground 
was carefully worked as the parties moved along. A summary of the 
joint list is here given, and in interesting cases the distribution 
added from the Locality Register. Ranunculus circinatus Sibth.
