The anatomical record . ing with a consideration of thesimplest type and proceeding to the larger and more complextypes. In figure Il, A, H and (, are reproduced three renaltubules taken frcjni the more peripheral i)ortions of one ofthe lobules of the kidney of an adult rooster. lOach is completefrom renal corpuscle to collecting duct. A comparison of thesefigures with the figures here given of the reptilian renal tubule,especialh .\ and B, of figure 5, will show tliat there exists a RENAL TUBULES OF VERTEHRATES 327 marked morpholot^ic similarity in form ami arrangompnt ofparts of tlio reptilian and certain avian renal tubules. In eachof the three tubules reproduced in figure lo, the renal corpuscleis relatively small and of nearly spherical form. Kaeh is joinedto the respeelive tubule by a narrow iieek. This is followed by atubular segment which constitutes the proximal convolutedportion, arranged in each of the three tubules figured in the formof a letter N, each part of the \ presenting numerous secondary. intseg.
