60 THE HOUSE I LIVE IN. 



The braces here alluded to are, 



1. The Collar Bone. This forms a kind 

 of brace between the shoulder and the breast 

 bone, and so nearly resembles a rib, that a 

 separate cut, to show its shape and position, 

 seems unnecessary. You will see it in two or 

 three of the engravings, running across from the 

 shoulder to the breast bone or sternum. 



2. The Shoulder-Blade. This is a broad, 

 flat bone, with ridges on it ; and, at the fore 

 part, is the hollow, or socket, in which tKe 

 round head or ball of the humerus or arm-bone 

 lies and moves. Here is a view of it behind.
