west of Binegar, the continuation of which disturbance may, and 

 very probably does, run through the Vobster coal-district, to the 

 north of the Downhead anticlinal : and it would be quite capable of 

 producing the phenomena of the inverted Limestone-masses (see 

 Geol. Mag. Decade II. Vol. III. p. 457). 



My belief is, that had a diagram on a true scale (as regards the 

 configuration of the land and the great divisions of the rocks), been 

 attempted by those who now support the " overthrow theory," this 

 theory would never have found an advocate. Will Mr. Winwood 

 kindly furnish such a diagram ? Horace B. Woodward.

THE GEOLOGY OF ANGLESEA. 



Sir, — I do not clearly see the object of the paper by Dr. R. D. 

 Roberts, which appears in the May Number (p. 152). It is simply 

 a recapitulation, from his point of view, of the arguments which 

 have already been submitted by us to your readers, with whom the 

 matter, so far as I am concerned, must now rest. It is, perhaps, 

 rather singular that Dr. Roberts should strive so persistently to hunt 

 to the death an argument which was adduced by me in support of 

 a conclusion which he himself accepts, viz. the Archaean age of the 

 granitoid series. I must decline to adopt his views as to the mode 

 in which I shall use my private note-book. I claim to be the best 

 judge of what is essential or non-essential to my argument. The 

 faulted sections have not been published, simply because they are 

 not required. Dr. Roberts evades the difficulties which I pointed 

 out in his reasoning on the sections at Bryngwallen and Penlon, on 

 the pretext that he has discussed them in his dispute with Prof. 

 Bonney. This is quite erroneous, as those who have followed the 

 controversy can judge. 



From Dr. Roberts's paper, your readers will have learned, 

 probably not without surprise, that he sent to you his list of my 

 " errors " at a time when he had not access to my papers, and they 

 will know how to estimate the accuracy of a critic who can make 

 sweej)ing charges against another, without taking the trouble to 

 ascertain if he is truly representing his opponent's views. Dr. 

 Roberts has, however, candidly apologized for one of his random 

 assertions ; and the other corrections will, I doubt not, appear in his 

 next communication.

THE HEADON HILL SECTIOK 



Sir, — Possibly Prof. Judd's letter in the April Number may have 

 been read by some who had not seen mine. I therefore ask you to 

 reprint the portions to which he refers. I wrote : — 



" When we recollect that one of the authors (of the paper under 

 discussion) was born in the Isle of Wight, and spent the best years 

 of his life in professional work, chiefly in exploring and collecting 

 from the Eocene beds of the district, some little amount of warmth
