be the true Dlflblvent of theTin<^lure of the Madder, 
and might convey it to the Place whither it carries 
Nourilhment to the folid Parts of the Body of thefe 
Animals. In confeqnence of this Conjecture, which 
I fhall refume in the Sequel, I thought that the Ske- 
letons of young Animals ought to take a ftronger and 
quicker TinCture, than thole of full-grown Animals; 
becaufe the Bones of young x\nimals are in a State 
of Growth, which requires a greater Qiiantity of 
ofleous juice. It is likewife true, as above faid, that 
it is the hardefl: Bones of young Animals, that imbibe 
moft of the Colour. All thefe Confiderations gave 
Rife to a Difficulty, which was to be cleared up. 
Wherefore, in the Beginning of laft Odiober, I 
chofe Two Turkeys of the Year, the ftrongeft I 
could find, and young Pigeons in their firft Hair or 
Down. 1 could wifh to have made the Experiment 
on Animals of the fame Species ; but it was impof- 
fible to find young Turkeys in their firft Down at 
that Time of the Year : And befides, thefe Ani- 
mals being extremely tender during the firft Months, 
their Stomach would never have been able to bear 
the EfFcCl of the Madder. As to old Pigeons, I 
had no tame ones : The wild are difficult to be fed 
with the Pafte ; and if they were fuffered to feed at 
Diferetion, they would not have been fufficiently 
madder ed, if I may be allowed this Expreffion. 
However, the Bones of my Two Turkeys were very 
hard, in comparifon of thofe of the young Pigeons : 
And thus I had in thefe Animals, though of different 
Kinds, all that was of Importance for my Expe- 
riment.
