the Madder y and from time to time I gave them the 
Pafte without it. The Root had already produced its 
EfFed 5 for notwithftanding the new Regimen, they 
continued' to waftej which obliged me to kill the 
Third Five Days alfter the Death of the firft Two. 
The Colour of its Bones was not different from that 
of the Two, who died Five Days before. As to the 
Fourth Pullet, which feemed not quite fo fick, I 
marked it on the Leg with a Bit of Cloth tied 
round, and fet it at Liberty. It recovered by de- 
grees, by chooling Food to its Tafte in the Yard. 
But at the fame time the Tindure its Bones had 
received, went off gradually, and almoft intirely dif- 
appeared in a Month’s time. For I took care to 
obferve the Change every fecond or third Day, by 
looking at the Bones on the Under-fide of the Wing, 
which have no other Covering than a thin Skin. 
From this Experiment, as from that of Mr. Bel- 
chiers Cock, it appears, that the Madder-root is 
alone fufficient to tinge the Bones of Animals red, 
which eat it. The Bones of my Pullets had taken 
no more than a Rofe-colour ; becaufe thefe Crea- 
tures, being difgufted with their Food, never eat of 
if, but when urged by extreme Hunger: And I had 
never been able to tinge them of a fine red Colour, 
had I not repeated the Experiment on fuch Animals 
as I could feed with - the Pafte, and had it in ray 
Power to make them fwallow Madder in large 
Quantities. 
For that Purppfe I ehofe young Pigeons, the 
ftrongeft of a whole Pigeon houfe. Two of thefe 
had no other Food given them but Wheat-meal, 
others were fed with the A4eal znd Madder -mixzd 
and
