nary doors, with common spring-catches in the middle. But the 
' floor-cases may be taken to 
represent the best that can be 
constructed in the light of Dr. 
Gray’s extensive experience 
and long observation. They 
have the important advantage 
of being out of contact with

and the rods enter brass sockets in the case above and below the 
door. The pointed tips of the rods and the outer beveled sur- 
face of the middle catch cause the door if it becomes warped to 
be drawn forcibly into place as the handle is turned. Thus at
