"THE PEOBLEM OF THE LIZARD ROCKS." 

 By B. A. WiJNSCH, F.G.S. 



The geological structure of the Lizard district may be 

 stated, without fear of contradiction, to have been the subject of 

 as assiduous research and earnest investigation on the part of 

 eminent geologists of the past and present generation, as any- 

 other well known district in the British Isles. 



Not only have men like Delabeche, Sedgwick, and other 

 contemporary authorities in geology brought their lifelong 

 experience to bear upon the subject, but before them and along 

 with them, earnest and gifted local investigators have trodden 

 the ground over and over again, and each has left some valuable 

 records, some addition to the general stock of information upon 

 the subject. 



The work of the preceding generation has been taken up 

 and carried forward by living geological investigators, promin- 

 ently amongst whom figures Professor Bonney, whose several 

 papers upon the subject, dated 1870 (?) and 1881, have become 

 classical with the geological student. But still more recent 

 enquirers have followed Professor Bonney, and most recently, 

 within the recollection of the members and office bearers of this 

 Society, who accorded such a cordial welcome to their guests of 

 last summer, the Greologist's Association of London (headed by 

 their President, and including some names of mark in geology), 

 paid a special visit of investigation to the Lizard district. 



A further significance of the importance of this problem of 

 the rocks of the Lizard district, is given by the fact that the 

 forthcoming meeting of the British Association is to take place at 

 Bath (in September next), which is sufficiently close to the borders 

 of Devon and Cornwall to make it likely that the Lizard rocks may 

 form a prominent subject of discussion in the geological section 

 — and may attract a number of visitors to the district at the close 

 of the meeting, — and the interest of the subject is further 

 heightened by the co-incidence that geologists from all parts of
