474 Mr. P. J. Martin on the Anticlinal Line of 



dered. At the time I suggested the use of the word " Wealden*/' 

 which was adopted by Br. Fitton and Sir H. De la Bechcf, I 

 also advocated the use of the word " Glauconite '' for greensand, 

 upper and lower, and to include everything from the chalk to the 

 Wealden. If this also had been adopted, it would have been 

 taken up by the French geologists, who would have found their 

 subdivisions of Glauconie crayeuse and Glauconie sabloneuse con- 

 veniently included, and we should not have been incommoded 

 by the introduction of the synonym of " Neocomien.^^ Or if 

 Dr. Fitton (who of all men has the greatest right to be name- 

 father in such a case) had given earlier enunciation to his happy 

 thought of " Vectine,^' the propriety and convenience of such a 

 collective appellation for all the members of the lower part of 

 the cretaceous system, must have assured its general approval 

 and adoption. 



Evidence of upheaval. — As the evidence of the continuation of 

 the same upheaving forces, from the great denudation of the 

 Weald westward into what I have called the great chalk dome of 

 Hampshire, is a matter of so much importance, I have again 

 visited the line of country pointed out by Dr. Fitton as likely to 

 contain signs of disturbance, bringing the eastern and western 

 denudations into direct relation with each other. 



I am induced to dwell on this point more particularly, be- 

 cause in his map of the Weald, and adjoining country, Mr. Hop- 

 kins has drawn an imaginary line round the ^^ disturbed district J,^' 

 which conveys to the cursory observer, more strictly perhaps 

 than the author intended, the notion, that the signs of disturb- 

 ance are confined within those limits. We are to imderstand 

 only, I believe, that within the area so described, the best evi- 

 dence is to be found in exemplification of Mr. Hopkins^s 

 ''Theory of Elevation.^' 



The last examination, the third I have especially made of this 

 line of country, confirms my opinion of the projection of the 

 Winchester anticlinal westward, as far at least as the banks of 

 the Test, and eastward into the great valley of the Weald by the 

 Vale of Meon ; the high grounds between these two points being 

 the true continuation of the elevation of the South Downs. The 

 valley which carries the Itchin from Alresford to Winchester ia 

 the synclinal of this elevation, and is, as I suspected, occupied 

 by " lower tertiary." 



In the above-mentioned visit, I discovered a flexure and fault 

 in the Malm rock north of the new church at South- Harting, 

 which I suspect to be the expiring point of this line of disturb-
