 Head. 



He suggested, however, that possibly the bones and shells

Dr. Joule, in reference to speculations on the thickness of 

 the earth's crust, stated that he had some time ago received a 

 letter from Professor Thomson, giving an account of the

 interesting subject. Professor Thomson finds that the
