and possibly quadratics at Taplow, cor-anguinum again soutli and 

 west of Taplow to the margin of the area, where Marsupites comes on 

 again. In this part of the area, at any rate, Mr. Baker's zonal 

 houndaries, deduced from borings, are in marked discordance with 

 the facts ascertained and published. 



I do not, however, wish to suggest that the method of deducing 

 the Sub-Tertiary zones from boring records is useless ; on the 

 contrary, when the amount of evidence available is larger, the 

 method may be of some value. The results obtained by Mr. Baker 

 show that his evidence is insufficient, but that may be because he 

 has apparently not made use of all the evidence available. For the 

 benefit of those interested in the subject I may add a few points not 

 mentioned in the paper I am criticizing ; all are referred to in the 

 memoir I have quoted, while the first was published in 1886. At 

 Egham the Chalk Rock has been proved at a depth from the surface 

 of 700 feet, or 346 feet from the top of the Chalk, suggesting the 

 presence of quadratus zone ; at Ottershaw the total thickness of 

 Chalk is known to be 646 feet, suggesting Marsupites ; at "Windsor the 

 Chalk is exposed below the Tertiary and probably belongs to the 

 lower part of cor-anguinum. 



From this evidence, combined with that referred to by Mr. Baker, 

 I inferred that the plane on which the Tertiary rests " has been cut 

 across a series of gentle folds whose axes run about E. 15° S." 

 (op. cit., p. 14). I do not regard the above as more than a tentative 

 solution of the problem, and it refers only to the southern half of the 

 area mapped by Mr. Baker (Fig. 1), but I wish to point out that his 

 conclusions must at any rate be regarded as " not proven ". 



I do not understand the suggestion on p. 299 that "the Streatham- 

 Beckton fault is pre-Tertiary ". It is certainly post-Tertiary, since 

 it involves the Tei'tiary strata and dislocates the upper surface of 

 the Chalk. Whether there was pre-Tertiary movement along the 

 same line we have as yet no means of ascertaining.

WILLIAM LOWER CARTER, M.A., F.G.S. 

 Born August 9, 1855. Died June 19, 1918. 



William Lower Carter was born at Stafford and educated at Derby 

 SchooljWherehe distinguished himself in Natural Science. On leaving 

 school he commenced work in a bank, but having a strong desire for 

 theological studies he entered as a student at Springhill College, 

 Birmingham, matriculating with first-class honours at London 

 University. From Springhill he proceeded to Cambridge, having 

 gained an Exhibition scholarship at Emmanuel College, where he 

 again took up Science classes and passed the Natural Science Tripos 

 Examination with honours, specializing in Geology. Leaving 

 Cambridge he spent some time at the University of Halle in Germany,
