ing on his consciousness of my having done nothing fraudu- 

 lent or dishonourable, but because he found that he had 

 outwitted himself in fabricating a charge against me wliich 

 he had not the hardihood to abide by, or the tact to defend. 

 In proceeding to the correspondence, which includes both 

 the charges against me, I shall in this place, merely request 

 the readers especial attention to the letters between Prof. 

 Owen and Mr. Wood.

Mr. Charlesworth has heard with surprise, that Mr. Lyell, when in com- 

 munication with parties to whom Mr. Charlesworth is personally known, 

 has attributed to him the appropriation without acknowledgment of infor- 

 mation derived from Professor Owen, in reference to a paper in the last 

 * Magazine of Natural History.' 



Mr. Charlesworth begs to inform Mr. Lyell that the article in question 

 did not embody any information derived either directly or indirectly from 

 Professor Owen, Mr. Charlesworth having had an opportunity of satisfying 

 himself as to the probable affinities of the fossil forming the subject of his 

 paper, without availing himself of the access always readily gi-anted him 

 by Mr. Clift and Professor Owen to the osteological collection in the Col- 

 lege of Surgeons. Mr. Charlesworth is at a loss to conceive the motive 

 that has induced Mr. Lyell to attempt to create an unfavourable prejudice 

 against him, but he trusts that he shall be able to satisfy those among his 

 friends to whom the matter may have been named, of the entire absence 

 of any foundation for the impression which Mr. Lyell has so anxiously 

 endeavoured to produce.

 In reply to Mr. Charlesworth's letter, Mr. Lyell begs to state that he 

 believed, and expressed his belief to several friends, that Mr. Charlesworth, 

 when he wrote on a mammiferous fossil found at Kyson (in the Sept. No. 

 of Mag. of Nat. Histy.), had been already informed that Mr. Owen had 

 previously examined the first mammalian tooth discovered at Kyson, and 

 that Mr. Owen had given an opinion that it belonged to an opossum, — a 

 result which Mr. Lyell had widely circulated. Mr. Lyell also thought 

 that Mr. C, when expressly mentioning the first-discovered tooth in ques- 

 tion, should have alluded to the circumstance. 



But if Mr. Charlesworth had not become aware of any conclusion pre- 

 viously arrived at respecting the first fossil, Mr. Lyell will have great 

 pleasure in informing the only friends to whom he has spoken on the sub- 

 ject, that he had laboured under a mistake.

Mr. Charlesworth has the honour of acknowledging Mr. Lyell's reply to 

 his note of yesterday, in which Mr. Lyell remarks that he thinks Mr.
