the Cambridge Green sand, which had not only resulted in great com- 
mercial success to the workers, but had added to the material wealth 
of the nation as fertilizers. 
At the close of the discussion, Mr. Charlesworth called attention tu 
some very interesting specimens of peculiar dental structure, one being 
the head of the narwhal, with tooth some 8ft. long in situ, and sup- 
plemental germ-tooth lying in the skull. Few examples of two 
developed teeth were known. Another was the jaw of the wart-hog of 
South Africa, a very abnormal structure, similar as regards the denti- 
tion to that of the elephant. He then drew attention to some very 
curious perforations in the teeth of sharks from the Red Crag, pro- 
ncunced by Professor Owen as probably produced by human agency. 
The subject was under examination by a Committee of the Anthropo- 
logical Society. Some of the boring creatures usually met with seemed 
not to have been the agents in perforation, and Mr Charlesworth 
thought they are only simulations of human workmanship. 
Mr. Wownror also stated that Mr. H. Willett had offered to place 
at the disposal of a Committee appointed by the Society the specimens 
obtained in the Wealden borings, for examination geologically, 
chemically, and microscopically, and to provide a room where the 
examination could be carried on. The Committee recommended that 
Mr. Willett’s offer be accepted ; that Messrs. T. Glaisyer, T. H. 
Hennah, J. Howell, G. Scott, C. P. Smith, W. H. Smith, J. 
Schweitzer, Dr. Hallifax, Captain Marshall Hall, and the Hon. 
Secretaries (Messrs. T. W. Wonfor and J. C. Onions), with power to 
add to their number, do form the Committee ; and that the Society 
subscribe five guineas towards the expenses of the Ashburnham borings. 
It was also announced that the Executive Committee of the British 
Association had asked the co-operation of the Society in arranging a 
‘Living Flora of the South Coast,” and other objects of interest, 
including a scientific microscopic display, for the soirées and temporary 
museum, to be held in the month of August. The Committee 
recommended that the request be complied with, and that a Committee 
be appointed to carry out these objects.
