24 TALPA. 
If the reader will compare this figure with the skeleton 
of the bat’s hand in cut 5, he will see the two extremes, as 
to length and breadth, in the development of the bones of the 
anterior member in the Mammalian class; yet the analogy 
of their respective organizations is perfect, and carried out 
to the least of the component ossicles : the same parts being 
adapted by different proportions to their very different func- 
tions. The unity of plan bespeaks the One Great Cause, as 
the Supreme Wisdom is testified by the perfect fitness of the 
instruments for their specific end; nor is the combination 
of typical conformity, with exact adaptation to the destined 
function, less manifest in the hand which guides the pen, 
than in that which moves the Bat through the air and the 
Mole through the earth. 
The most complete fossil skeleton of the Mole is that, 
of which the parts are above described, now in the Norfolk 
and Norwich Museum: it was discovered by Mr. Green.* 
* The specimen, with the bones collocated according to the first notion of their 
nature, forms the frontispiece to Mr. Green’s ‘ Geology of Bacton.’
