APPENDIX. 



About three weeks after this, but still before 

 the British Association met at Birmingham, a 

 third mammiferous tooth, (see fig. 3.) but widely 

 differing from either of the two former ones, 

 was obtained by Mr. Colchester, and given by 

 him to me, for publication in the Magazine. 

 The opportunity of doing this was only what Natural size 

 I had in common fairness some claim to, because it was I 

 who had induced Mr. Colchester to form a collection of 



the fossils from the numerous and rich localities in the 

 immediate neighbourhood of his residence, and to whom he 

 was indebted for the information that the tooth (No. 1) was 

 that of a mammal. 



Mr. Lyell went from Kinnordy, in Scotland, to the meeting 

 of the British Association at Birmingham in August, and there 

 announced to the Geological section, the discovery of mam- 

 miferous teeth in the London- clay of Suffolk ; my own his- 

 tory of the third tooth was coming out in the number of my 

 journal for the following month (September), but thinking 

 that any information on so important a matter, would be ac- 

 ceptable to the Geologists assembled at Birmingham, I sent 

 down some printed copies of the paper to the Secretary, Prof. 

 Phillips, but not until Mr. Lyell had read his paper on the 

 tooth (No. 1), and thereby secured to himself the credit of 

 being the first to make known so important a step in the 

 history of English Geology. 



I now turn to the authenticated reports in the Athenaeum, 

 to make an extract from Mr. Lyell's observations upon the 

 tooth (No. 1). This fossil has since turned out to be, like 

 No. 2, the tooth of a monkey, and not as at first pronounced 

 by Prof Owen, that of an opossum. The passage I shall 

 quote is from page 676 of the 'Athenaeum' for September 7, 

 1839. 



No. 27. 



" Mr. Lyell then mentioned the discovery of the teeth of an opossum 

 in the London clay at Kyson, near Woodbridge. This fossil, also 

 from the collection of Mr. Colchester, was obtained, together with the
