Sivu xxxiv - Ungulata — with what, I am disposed to think, is a fair and probable approximation to the order of nature. But, as no one is better aware than these two learned, acute, and philosophical biologists, all such arrangements must be regarded as provisional, except in those cases in which, by a fortunate accident, large series of remains are obtainable from a thick and widespread series of deposits. It is easy to accumulate probabilities — hard to make out some particular case in such a way that it...
Sivu xlix - Huxley, in his presidential address to the Geological Society of London in 1870, treats of the distribution of animals and says of his hypothesis that it " requires no supposition that the rate of change in organic life has been either greater or less in ancient times than it is now ; nor any assumption, either physical or biological, which has not its justification in analogous phenomena of existing nature.
Sivu xxx - The significance of persistent types, and of the small amount of change which has taken place even in those forms which can be shown to have been modified, becomes greater and greater in my eyes, the longer I occupy myself with the biology of the past.
Sivu xxxiv - It is no easy matter to find clear and unmistakable evidence of filiation among fossil animals; for, in order that such evidence should be quite satisfactory, it is necessary that we should be acquainted with all the most important features of the organisation of the animals which are supposed to be thus related, and not merely with the fragments upon which the genera and species of the palaeontologist are so often based. M. Gaudry has arranged the species of...
Sivu xxxii - Therein will be found a pretty full statement of my reasons for enunciating two propositions : (1) that " when we turn to the higher vertebrata, the results of recent investigations, however we may sift and criticise them, seem to me to leave a clear balance in favour of the evolution of living forms one from another ; " and (2) that the case of the horse is one which " will stand rigorous criticism.

And here I beg leave to express my sense of the wise appreciation of the needs of the palaeontologist by the Council of the Society in publishing figures of the type molars of those " Transitional Mastodons"f of the natural size.
