THE PROBLEM OF THE LIZARD ROCKS. 367 



the Lizard, and all you have to do is to study the laws and watch 

 the nature of their growth, and to apply the knowledge thus 

 obtained to the elucidation of the mysteries of the Lizard rocks. 

 Add to this the most recent work of Mr. Teal in stratigraph- 

 ical and microscopical geology, — with special reference to the 

 Lizard district, — carried on in conjunction with Mr. Howard Fox, 

 and cap it with all the information and hope, to be derived from 

 Professor Geikie's most recent and brilliant paper on the infinite 

 changes and plications of the crystalline rocks of the Highlands, 

 a paper which is the outcome of the joint labours of a number 

 of zealous and experienced workers in practical geology, and 

 which, in conjunction with the latest ingenious experiments on the 

 extraordinary mechanical foldings and plications of rocks under 

 pressure, throws a flood of light not only on the actual structure 

 of the Scottish crystalline rocks, but also on all similar rocks 

 wherever they may occur. 



I hope then to have indicated in mere outline, and perhaps 

 not as hopefully as some may have been led to expect, the problem 

 of the Lizard rocks. The only hope of ultimate success lies in 

 again attacking the question from its very foundation, armed at 

 all points and in every detail, and there is no reason for believing 

 but that the present and rising generation of geologists will be 

 qualified by brain, eye, and hand to do so successfully.
