young Pigeon with Madder, but in fmall Quantities, 
for fear of killing it too foon. It lived Eight Days 
longer without any Appearance of the Bones being 
deeper coloured than the firft that were killed. 
All thefe Creatures, that had been fed with the 
Mixture, were differed j and I made the following 
Obfervations on them. 
Neither the Feathers, the Horn of the Bill, nor 
Claws, had changed their Colour, even where they 
are inferred into the Skin. The Skin of the whole 
Body had preferved its natural Colour. The Brain, 
Nerves, Mufcles, Tendons, Cartilages, and 
Membranes, afforded nothing to the Sight contrary 
to the ufual State of thefe Parts. But the long bony 
Tendons, that run along the great Bone, which is 
improperly called the Leg of Fowls, were red about 
the Middle of their Length, which is their hardeft 
Part. All the true Bones, even to the very thinneft 
of them, were as red as Carmine; and in fomc 
Places this Red was fo deep, that they appeared almoft 
black. 
In thefe young Birds, all the Bones do not take the 
red Tinge alike. The hardeff are generally more 
coloured than thofe that are tenderer. A Difference 
of this kind is perceivable even in the fame Bone ; 
for the Middle, which has more Solidity than the 
Ends, is almoft always the reddeft. Not but there 
are fometimes found little pale Spots in the Part 
where the Red is deepeft ; and fometimes Spots of 
a very deep Red in thofe Parts which have taken but 
a Carnation Tinge.
