THE HISTORY OF ANATOMICAL SCIENCE 31: 
suggestions j Von Meyers long series of wonder- 
fully accurate memoirs, with their admirable illus- 
trations executed by his own hands, all belong 
to Owen’s generation. But, perhaps, the fairest 
comparison is with Cuvier ; and I do not think 
that those who have had to concern themselves 
with these subjects will rank any of Cuviers 
memoirs higher than those of Owen on Mylodoii, 
MegathcviuTii, Glyptodon^ McicTctuchcnio,, and 
other extinct South American animals, which 
followed up the account of Toxodon. 
In 1838 appeared the memoir on the Stone- 
field Slate mammals, then the oldest known, 
pointing out their marsupial affinities, and with 
this the later investigations on the Purbeck mam- 
mals may be grouped. In 1839-40, we have 
the first indication of the wingless birds of New 
Zealand, widening out, in after years, into the 
long senes of memoirs on DmoTitis and the like. 
In 1841, the description of the triassic Laby- 
rinthodonts of Central Kngland, which, with 
Von Meyer’s earlier and later work, was the 
commencement of the elucidation of the triassic 
fauna in all quarters of the world, made its ap- 
pearance. In 1844, Owen published the memoir 
on Belemnites, which had a distinct value, 
though not perhaps quite that assigned to it at 
the time. In 1845, followed the first view of 
the wonderful extinct faunae of South Africa and 
Australia, so largely extended by Owen himself
