of the glomerulus, after entering the capsule of Bowman, immediately 
divides into five diverging branches, which with their subdivisions 
and with the efferent vessel form an almost spherical tuft of blood 
vessels. For the sake of description we may assume that the glo- 
merulus is suspended from its afferent vessel. The efferent vessel origi- 
nates, roughly speaking, from a loop of capillaries which project in the 
equatorial plane from the side of the glomerulus opposite the efferent 
vessel, but to the right of the 
median line (Fig. 2 E.V.) From 
this point the course of the 
efferent vessel is upward, in- 
ward, and to the left, grooving 
the superior surface of the 
glomerulus and dividing it 
into two unequal parts. This 
vessel leaves the glomerulus 
a little superior and anterior 
to the point where the afferent 
vessel divides and in a direc- 
tion opposite to that of the 
efferent vessel. (Fig. 1.)

The left lateral group of capillaries is separated from the median group and turned back, 
exposing the interior of the glomerulus. a A short ‘section of a capillary of the median 
group is removed to shew the course of the deeper lying capillaries.
