NOTICE. 



in the Paleeontologia Indica, I should hold myself respon- 

 sible for any such errors ; but I am quite satisfied that they 

 do not occur. 



3. As regards the question of responsibility : there was 

 no chance that Mr. Wynne would be held accountable for 

 the identification of the Obolus as a silurian fossil ; but as 

 a geologist he is responsible for forming or for adopting the 

 opinion that certain beds are of silurian age, on the evidence 

 of a single Brachiopod; and it would have been quite 

 uncalled for in Dr. Waagen to have disputed such an opi- 

 nion in a geologist of Mr. Wynne's standing ; an opinion in 

 which he did not stand alone, Dr. Oldham having announced 

 the same conclusion (Records, VII, p. 64), which was not 

 an unreasonable one in a provisional way, and apart from 

 the consideration of collateral evidence. It was, however, 

 especially incumbent on Mr. Wynne to examine, exhibit, and 

 be guided by the stratigraphical features for or against such 

 a correlation of the groups ; and. it is presumable that he is 

 satisfied in both respects, for in the present memoir the silu- 

 rian age of the lower deposits is still affirmed (p. 90) ; the 

 point is, indeed, as yet not finally disposed of. But this 

 question of responsibility is a secondary point in the argu- 

 ment as now presented by Mr. Wynne. 



4. It is upon the point of misrepresentation that most 

 stress is laid, and Mr. Wynne puts himself in an unaccount- 

 able dilemma: from a position that is quite plausible and 

 logical, if not sound, he assumes one that is illogical and un- 

 intelligible. Bath in his table of the Salt-range series, which 

 for the part under discussion Dr. Waagen reproduces exactly, 

 and in his text, Mr. Wynne in the fullest sense declares 

 the silurian age of the Obolus bed : at page 68 (Memoirs 

 Vol. XIV), he mentions the Obolus as "determined by
