Investigations on the Life-History 



TABLE X. 



Per Cent. Phosphorus in Lecithin. 

 ESTUARY FISH. 



UPPER-WATER FISH. 



TABLE XI. 



Per Cent. Phosphorus not as Lecithin. 

 ESTUARY FISH. 



It is thus seen that there is no great increase in the per cent, of 

 phosphorus as the testes increase. 



To show the extent of the exchange of phosphorus the amount of that 

 substance per fish of standard length as lecithin and not as lecithin may 

 be compared in 13, a fish leaving the sea in May, and in 68, a fish 

 in the upper water in October. 



Table XII. gives the Phosphorus as Lecithin (A); the Phosphorus not 

 us Lecithin (B) ; and the Total Phosphorus (C) per fish of standard 

 length.
