TUDOR SPECIMEN OF EOZOON.

examined the Tudor specimen, and could not recognize in it the 

 Eozoonal structure willi which he was familiar in the ordinary spe- 

 cimens. At the same time the specimen, though by no means so 

 distinct as the published jdatc of it represented, had a curiously 

 organic-looking aspect ; and he thought it probable that the pala3on- 

 tologists would not surrender it to the mineralogists without a more 

 vigorous struggle than had been attem])ted that evening. 



Prof. Elake, having satisfied himself of the inorganic nature of 

 Eozoon at St. Pierre, had been to Tudor without obtaining any light 

 on the specimen. The crystallization of the material and its passing 

 into the cracks might be due to subsequent mineralization, and the 

 evidence of bedding passing across the specimen was doubtful, but 

 the specimen itself was perfectly convincing. He was sure that 

 Sir J. ^^^ Dawson never expected the so-called " fossil " would die 

 out like cracivs within J inch of the flat surface, which was quite 

 incompatible with its being organic. 



The Afthor, in rey)ly to Prof. Blake, recapitulated the evidence 

 in favour of the bedding-planes, and stated that several objections to 

 Sir J. W. Dawson's explanation of the thinness of the specimen were 

 stated in the paper. The supposed definite margin of the specimen 

 was due to the fact that the calcite-bands had only been developed 

 on the weathered surface of the slab. Every English palaeontologist 

 who had examined the specimen and slides agreed that it was 

 inorganic.
