SUMMARY OF PROCEHEDINGS AT MEETINGS. SOX 
supported the primary quills of the wing are not 
seen on the surface of the specimen but still lie 
embedded in the slab. This conclusion is supported, 
first by the indication (by a shadow in the photo- 
eraph) of a ridge on the slab corresponding in position 
with metacarpals similar in size to those which 
support the feathers of an ordinary bird’s wing» 
and the same conclusion is more forcibly supported 
by the fact that such bones are actually visible in 
the London specimen and were figured by Owen 
in the Philosophical Transactions of the Royal 
Society thirty years ago. 
From this conclusion, if it can be established by 
careful excavation of the Berlin slab—perhaps from 
the back—it will follow that the three digits of the 
recent bird’s wing are the third, fourth and fifth ; 
a view which does not appear to be opposed to 
anything which is known of the comparative 
anatomy or embryology of the wings of existing 
birds, with the sole exception of an observation by 
W. K. Parker which the writer professed himself 
unable to verify. Dr. Hurst’s remarks were illus- 
trated by lantern slides. 
7. Mr. I. C. Thompson laid on the table his Revision of 
the Copepoda of Liverpool Bay. (See “‘ Transac-

The sixth meeting of the Society was held at University 
College on Friday, 10th March, 1893. 
1. Mr. H. C. Beasley exhibited with the lantern photo- 
graphs of the series of footprints in Triassic Sand- 
stone now in the Bootle Free Museum. The slabs 
bearing the footprints were originally in the Royal 
Institution, but some years ago were removed with
