Thefe laft Experiments prove with what Expedition 
the Diftribution of the nutritious Juice is performed 
in Animals of this kind, which acquire all their 
Growth in a few Months ; and how rapid the Diftri- 
bution is, even in thofe Parts where the Blood’s Cir- 
culation meets with the g^reateft Obftacle, as in the 
Subftance of the Bones. 
As one ought likewife to infer from thefe Experi- 
ments, that there are vegetable Medicines whofe 
chief Tendency is to the Bones, and which confe-

looked on myfclf obliged to employ the Madder 
with this View ; but not having it in my Power to 
raife Difeafes of different kinds in the Bones of my 
Animals, I confined myfelf to the Examination of 
what Effed it would have in a Eradure.

Thigh-bone of each of them was broke; the Re- 
dudion was immediately performed, and fecured by 
a proper Bandage. Two of thefe Pigeons were fed

the Meal alone. Thefe laft, notwithftanding the 
Pain the Fradure muft have given them, had always 
a good Appetite, and in Eight Days they began to 
walk with their Drefling, which was a little loofened. 
The others fell into the Accidents already mentioned, 
and died, one on the Tenth, the other on the Four- 
teenth Day. The Two Pigeons that had recovered 
were killed, in order to compare the Callus. 
That of the Pigeons which had not taken any 
Madder, was little, clofc, and very even : That of 
thofe fed with this Root, was large, fpongious, and 
'uneven : There fhot out of it a fort of Vegetation : It
