THE CHAET OF FOSSIL SHELLS FOUND IN CONNECTION WITH 

 THE SEAMS OP COAL AND IRONSTONE OF N. STAFFORDSHIRE. 



Sir, — In reading Mr. Walcot Gribson's review^ I was astonished 

 to see it stated that " marine organisms are represented as occurring 

 on three horizons," and also that the marine band above the Gin 

 Mine has been omitted. 



Writing with the Chart before me, and having personal knowledge 

 ■of the bands, I should like to correct what seems to me an un- 

 accountable error on the part of Mr. Walcot Gibson, who is usually 

 so accurate in his statements. The fact is that eight distinct and 

 separate marine bands are denoted, and moreover the Gin Mine is 

 represented by figures. 



The following are the horizons represented on the Chart as marine 

 beds, viz. : — 



1. Bay Coal Band. 



2. Priorsfield Band, 



3. Gin Mine Band. 



4. Single Two Feet or Moss Cannel Band. 



5. Weston Sprink Band (horizon doubtful). 



6. Seven Feet Banbury Band. 



7. The Wetley Moor Coal Band. 



8. The Four Feet or Crabtree Band. 



I should like to call attention to another point, to which I should 

 have expected Mr. Gibson specially to have referred. Various 

 attempts have been made to correlate the seams of the several 

 districts of this coalfield, generally on lithological or sequential 

 evidence. On this Chart the seams of the whole coalfield have been 

 successfully correlated for the first time, the marine bands forming 

 sure data lines. E. P. Turner.

SAMUEL CHADWICK. 

 Born 1845. Died March 18, 1903. 



The death is announced of Mr. Samuel Chadwick, who was one 

 of the founders of the Malton Field Naturalists' Society, and 

 devoted many years to the collection of fossils from the Jurassic 

 and Cretaceous formations of East Yorkshire. He left his native 

 county early in life to engage in sheep-farming in New Zealand, 

 but he returned after a few years and resided for a long period at 

 Malton, where his business aiforded him numerous opportunities of 

 prosecuting the geological studies in which he was deeply interested. 

 His early colonial experiences led Mr. Chadwick to emigrate again 

 to New Zealand with his family in 1895, and he died suddenly last 

 March at Moastone Park, Waikopiro. His remarkable collection of
