divides into two equally-sized branches, one of which plunges at 

 once into the parietes at the side of the vertebral column ; while 

 the other is continued forwards, and finally ends just opposite to 

 the emergence (on the left side of the vertebral column) of the left 

 dorsal hepato-parietal vessel, which passes to the liver by way of 

 the stomach. 



The Oviducal veins (text-fig. 90, p. 441) are somewhat compli- 

 cated. A continuous vessel, much contorted to allow for necessary 

 stretching, runs along the oviduct. Into this open altogether eight 

 transversely-rvinning veins in the case of both oviducts. These 

 may be divided into two series. The first six communicate directly 

 with the vena cava; the last two belong to the afferent renal system. 

 The six anterior oviducal veins seem, at least occasionally, to receive 

 brfinches fi'om the sujiiarenal body which lies in close contact

with the vena cava. In the case of the right oviduct the first of 

 the oviducal vessels which are connected with the renal system 

 has a rather complicated course. It is a very stout vessel, and 

 i-uns very nearly as far as the right vena cava, where it divides 

 into two iDranches (see text-fig. 91). The anterior of these branches
