200 MR. A. NEWTON ON SOME BONES OF DiDUS. [Feb. 14, 
stances which lead to the belief that the bird to which it belonged 
had been eaten by men or dogs. 
The bone found by Captain Barkly is a right femur. Though 
nearly perfect, it seems to have been much exposed to the action of 
the weather, and, in consequence of its condition, it has sustained a 
little damage by the crumbling away of some part of its extremities. 
This has probably happened since its discovery ; but one advantage 
results from the circumstance—namely, that the cellular structure 
of the bone is thereby rendered plainly visible. 
I proceed to give the dimensions of these specimens, and, for con- 
venience of comparison, I shall, as far as possible, follow Dr. Mel- 
ville’s plan of measurement (‘ The Dodo and its Kindred,’ page 116).

All those specimens, unlike those in the Paris Museum, are en- 
tirely free from incrustation. 
I believe there are no other examples of the humerus and femur 
of this species in this country. The specimen of the tarso-metatar- 
sus figured in illustration of Mr. Bartlett's paper, to which I before 
referred (P. Z. 8, 1851, Aves, pl. xxv. fig. 1) is, as 1 learn from Mr. 
Gerrard, now in the British Museum, and there are other examples 
of it in the Andersonian Museum at Glasgow. 
I must here tender my thanks to Mr. W. K. Parker for the kind 
assistance he has rendered me in accurately measuring these bones. 
And now I wish to make one suggestion. It is well known that 
at Oxford there is an old picture of a Dodo, painted by one of the 
Saverys, which seems hitherto to have been referred without hesi-
