EXPLANATION OF PLATES 1 TO 10 



Figs. 1 to 10, inclusive, were drawn to scale from dissections of adult mammals 

 and represent ventral views of the veins and lymphatic vessels in the renal and 

 lumbar regions. 



The veins are drawn in outline, the lymphatics are shaded, and the arteries, 

 when indicated, are cross-lined. 



The name of the species represented is given under each figure, while a complete 

 list of the mammals studied in connection with this paper may be found in the 

 table on pages 455-457.
