Investigations on the Life-History 



TABLE VIII. 



Phosphorus not in Lecithin per Standard Fish in Jfuscle and Ovaries. 

 ESTUARY FISH. 



UPPER-WATER FISH. 



Ovaries gained 7'478 grms. Muscle lost 9*200 grms. 

 Taking together the phosphorus as lecithin and the phosphorus not as 

 lecithin 



Muscle loses 9'97 grms. Ovaries gain 10*339 grms. 

 The phosphorus lost from the muscle is just about sufficient to yield the 

 phosphoric laid on by the ovaries, provided no phosphorus is excreted or 

 used in other ivays. 



(c) Pliosphorus of Liver. 



A possible source of the phosphorus is the liver. I have shown 

 that in many animals a considerable storage of lecithin may occur in 

 this organ. (J. of Phys., Yol. XIX., 1896, p. 167.) 



Although the amount of fat in the liver of the salmon is comparatively 

 small, it seemed desirable to ascertain if, during the period of fasting, loss 

 of phosphorus from the liver goes on to any marked extent. 



For this purpose six typical fish were selected, and the phosphorus of 

 the liver as lecithin and as other compounds was determined in the 

 usual manner. 



Table IX. gives the results of these analyses.
