" While the fisli is in the river this stored phos|)honis is 

 transiintted i'roin themusele to the growing" ovaries and testes, 

 and in biing- transmitted undergoes changes in its clieinical 

 combinations. In the ovary the siini)le phosphates of tlie 

 muscle are {a) combined with fatty acids and ciiolin to form 

 the abundant sup])Iy of lecithin ; {/>) combined with proteids 

 to form the pseudo- or ])ara-nuclein-ichthMlin — which is so 

 abundant a constituent of the ovary ; " (c) in the testes, on the 

 other hand, the jihosphorusof the musele-pliosphates is elabo- 

 rated with the more complex nucleic acid and combined 

 with the characteristic base — protamin. . . . 



" There is no evidence that the transference of phosphorus 

 from the muscles to the genital organs is not direct. There 

 is no evidence that the liver plays any intermediate part. In 

 fact, all the evidence tells against any such idea. It is api)a- 

 rently in and by the active |jrotoplasm of the growing ovaries 

 and testes that these profound cliemical changes are carried 

 out " (p. 155). 



** As to the source of the phosphorus stored in the muscle, 

 there can be little doubt that it is in great measure derived 

 from the ))hosphates in the bones of iierrings and other hsh 

 upon which the salmon feeds " (p. 155). 



In a female fish the balance between the phosphorus lost 

 from the muscle and that gained by the ovaries is fairly close. 

 " The jihosjJwrus lost from the muscle is Just about suj^cient to 

 yield the phosphorus laid on by the ovaries^ provided no phos- 

 phorus is excreted or used in other loays " (p. 152). 



" The liver cannot be regarded as the source of the phos- 

 phorus lor the ovaries, and it is rather to the bones that we 

 must look for any supply of this element over and above that 

 yielded by the muscles whicli may be necessary for the growth 

 of the ovaries " (p. 153). 



Although the testes are particularly rich in phosphates, it 

 would " a|)pear that the store of phosphorus in tlu; muscle is 

 far nioie than si.fficient to yield the phosphorus recpiired in 

 the constructive cliangos in the testes" (p. 155) — an interesting 

 conclusion in view of the fact that '* in the male during the 

 summer months there is a great growth of bone in the snout, 

 and it is highly probable tliat some of the phosphate stored 

 in the muscles is utilized in this ])rocess " (p. 155). 



Similarly J\lr. E. D. ^^'. Greig comes to the conclusion — 

 " (1) that the quantity of iron in the ovary becomes 

 distinctly increased during the development of that organ, 

 (2) that a considerable amount of its iron is derived Irom the 

 muscles, which become correspondingly |)Oorer in iron, {'6) tJjat 

 none ot it is derived fiom tlie liver." A su)all quantity
