 of the body with the uriniferous tubule. 



The surface of the glomerulus is covered with a layer of 

 squamous epithelium ("tuft-cells")? dipping down into the 

 depressions between the capillary-loops ; this epithelium is a

 it is continuous at the stalk of the glomerulus. 



Thus the glomerulus is "outside" the capsule of Bow- 

 man just as the heart is outside the cavity of the pericardium.
