2. That a Siccity or Brittlenefs in the Bones, in- 
clining them to a Fra&ure, may happen, independent 
from a Caries in the Bone : For, had the Os Humeri 
of our Patient been carious, at the time the Fra&ure 
happened from fo flight a Caufe as attended the En- 
deavour of bringing and joining together the oppo- 
fite Ends of a String held in the two Hands, it was 
morally impoflible the complete Cure of fuch a Frac- 
ture could be brought about within fix Weeks. 
Whence it appears, that the occafional Siccity of a 
Bone may be no Bar to the Flowing of that Quantity 
of Sap or callous Matter neceffary to operate the 
Cure after a Fra&ure. 
3. That the Mufcles muft have a great Share, as 
well in the Fradture of all Bones, as in the Difloca- 
tions of them } as in this Cafe the Os Humeri was 
broke by the Power and Adlion of the Mufcles only; 
and therefore that the keeping of them quiet, by 
placing the broken Limb in the mod natural and 
eafy Poflure, muft be highly inftrumental to the Cure. 
4. That the Abfortion, or Reflux into the Blood 
of a purulent Sanies , inflating the Part where it is 
lodged under the Appearance of an (edematous 
Phlegmon, or phlegmonous Oedema , is as dangerous 
as the Abforption by the Blood-veflels of a purulent 
Matter extravafated. So that the Reflux in either Cafe 
will again taint the Blood with the Corruption that 
had critically been flung out of the Courfe of the 
Circulation j and that, when this happens, there 
will be Caufe to fear a Renewal of the Complaints, 
and, poflibly, worfe Symptoms ; as has happened 
in the prefent Cafe.
