ovary, so that in each case there was present a fairly similar complicated 

 apparatus in connection with the testis-duct, although the testes were in 

 entirely different positions in regard to their appended ovaries. 



The extremities of the left ovary, both anterior and posterior, showed 

 no trace of a testis or a duct. 



In No. 2 there was an even more peculiar hermaphroditic tendency, 

 The ovaries in this case also differed in size, the left being 3| inches long 

 and the right 31 — the longer ovary, contrary to No. 1 , being that on the 

 left side. At the extreme posterior end of each ovary was situated a 

 testis (te n te„) ; that attached to the right ovary was large and much con- 

 voluted (see fig.), that on the left being very much smaller and with a 

 smooth surface. A closer examination revealed the presence of a very 

 small piece of testicular tissue (te u ) attached to the anterior end of the 

 left ovary and lying close to the ovarian vein running in the mesentery. 

 This testis consisted of a larger lobe, to which were attached laterally two 

 smaller ones. 



All three of these testicular masses (te t , te n , and te tl ) were attached in 

 a similar way to their respective ovaries by a continuation of their outer 

 covering, but I could not pronounce with any certainty as to the presence 

 or absence of any ducts putting them in communication with the ovaries, 

 as a superficial inspection only was permitted. As far as one can con- 

 jecture from external appearance, I should be inclined to think that the 

 two larger testes (te t and te t ) had ducts, but that the smallest {te n ) had 

 no communication with the ovarian cavity. 



Of course, for the reason above referred to, I cannot pronounce upon 

 the internal structure or contents of any part of this specimen, although a 

 few ripe ova were found at the mouth of the oviduct. This is sufficient, 

 however, to indicate the functional activity of the female element of these 

 hermaphroditic organs. 



Amongst the literature upon this subject there are three detailed 

 descriptions of cases of hermaphroditism in the cod-fish, namely, that by 

 Professor Howes,* already cited, in which he figures one specimen and 

 tabulates the results of examination of five others from the College of 

 Surgeons Museum ; that by Mr Alex. Smith, f in which he describes two 

 cases observed by himself • and lastly that by Professor Max Weber, in 

 which, together with an exhaustive inquiry into similar occurrences in 

 other fish, he figures and describes in great detail a specimen of Garfu* 

 morrhua. 



We may conveniently compare the various cases mentioned by arrang- 

 ing them in a table somewhat after the manner which Professor Howes 

 adopts in his paper already referred to : —
