into one another, so far as the character of the grinding 
teeth is concerned, to a degree to which the two existing 
species of Elephant, the Indian and African, when compared 
together, offer no analogy. 
Five or six molars of the Mammoth, and even a greater 
number, if the peculiar changes superinduced by friction 
on the grinding surface were not taken into account, might 
be selected from the series to which I have alluded 
as indications of so many distinct species of Mammoth: 
such specimens have; in fact, been so interpreted by Park- 
inson, and likewise by Fischer, Goldfuss, Nesti and Croizet, 
cited in the Paleologica of Hermann V. Meyer, as au- 
thorities for eight distinct species of extinct Klephant. 
We must, however, enter more deeply into the con- 
sideration of these varieties, before concluding that the 
Mammoths which severally exemplify them in their molar 
teeth were distinct species. In the first place, whatever 
difference the molars of the Mammoth from British strata 
may have presented in the number of their lamellar divisions, 
they have corresponded in having a greater proportion of 
these plates on the triturating surface, and likewise, with 
two exceptions, in their greater proportional breadth, than 
are found in the molars of the Asiatic Elephant. The first 
exception here alluded to was from the diluvial gravel of 
Staffordshire, and formed part of the collection of Mr. 
Parkimson, the author of the ‘ Organic Remains’; the 
second exception was from the brick-earth of Essex, and 
is now in the collection of my friend Mr. Brown of Stan- 
way; this molar, though it combines the thicker plates 
with the narrower form of the entire tooth characteristic 
of the Indian Elephant, differs in the greater extent of 
the grinding surface and the greater number of plates 
entering into the composition of that surface.
