APPENDIX. 47 



teeth of fish, from the upper part of a bed of sand about ten feet thick, 

 which is covered by a mass of London clay about seventeen feet thick. 

 The clay is again covered, at a short distance from Kyson, by the red 

 crag. Mr. Owen, on seeing this tooth, was clear that it could not be- 

 long to any of the decidedly carnivorous or herbivorous animals, but 

 rather to some one of the mixed feeders, and having compared it with 

 the teeth of the various tribes of quadrupeds included in that division, 

 from the shrews to the monkeys, he found it to differ essentially from 

 all of them ; and he finally decided that it was marsupial, and one of 

 the molars of a Didelphis allied to the Virginian opossum. Mr. Lyell 

 immediately requested Mr. Wood and Mr. Colchester to renew their 

 search in the same sand at Kyson, and they soon after found there a 

 jaw and tooth, which Mr. Owen refers to a quadrumanous animal of 

 the genus Macacus. The sand containing these remains is referable 

 to the London clay, and this is the first instance of the fossil remains 

 of Quadrtimana having been found in a deposit of the Eocene period.' 



Now, the tooth, which, in August, Mr. Lyell, on the autho- 

 rity of Prof. Owen, pubUcly stated to " diifer essentially" from 

 the monkeys, was found by Prof. Owen, in the beginning of 

 the following October, not only to be that of a monkey, but 

 to belong to one of the most common and best known genera 

 of the whole monkey tribe, — the Macacus. 



It would seem that the first charge set on foot against me 

 by Mr. Lyell, was, that in publishing the Woodbridge fossil 

 No. 3, (which, after a careful comparative examination, I 

 had referred to an opossum), I stood indebted to Prof Owen 

 for what 1 had said respecting it, and that I had made no 

 acknowledgement of that obligation, but had appropriated 

 as my own, the result of his investigation. This, at least, 

 was from what I could gather, the impression left upon the 

 minds of other parties from communications made to them 

 by Mr. Lyell. Now an imputation of this kind privately 

 circulated, or an obscure hint which might admit of such a 

 construction, emanating from so high an authority, was about 

 the best scheme that could have been devised for doing me 

 the greatest possible amount of injury in the fewest words : 

 the Editor of a scientific journal, from the nature of his 

 oflice, having so frequently in his hands, the unpublished 

 observation of others, and thereby being so peculiarly ob- 

 noxious to a charge of undue appropriation. 



When Mr. Lyell is taxed with having made the charge 

 just alluded to, he evades an explanation by complaining that 

 I had referred to the tooth No. 2, in his possession, as be- 

 ing like my own, (No. 3), mammiferous, but that I had not 

 mentioned the fact of its also being the tooth of an opossum, 

 which I ought under the circumstances to have done, having
