was structurally associated. If this interpretation be correct, the arterial 
vascular supply of the dog forms only an apparent exception to the gen- 
eral statement that all the arteriole recte are formed by a division of 
efferent glomerular branches, the few arteriole recte vere noted being 
regarded as developed from arteriole rect spurie on the disappearance 
of the uriniferous tubule structurally associated with the glomerulus 
which thus degenerates. Golubew has further described arterial twigs, 
which after division present one branch, which may be very short, and 
which forms an afferent glomerular vessel, the other branch passing by 
but in close contiguity to the glomerulus and dividing to form arteriole

recte—thus arteriole recte vere. This I have not observed and must 
regard it as an error of observation for which the method used by him 
(silver nitrate injection) is responsible, as is clearly the case in the fol- 
lowing observation, shown in his Fig. 2, Plate XXIV. Here is shown 
an arterial branch having a horizontal course, from the under side of 
which there arise several branches (six) which divide to form arteriole 
recte vere. ‘The preparation is taken from the base of the renal pyramid 
of the dog’s kidney injected with silver nitrate. The structure figured 
was undoubtedly a small vein receiving several groups of venule recte, 
as in corrosion preparations of the venous system of the dog’s kidney, 
such small vessels having a horizontal course and receiving on their under 
side small branches formed by the union of straight capillaries are fre- 
quently met with, but are traceable to larger venous stems. In corrosion
