of these c.g,-,c:s which seem, as viewed under the microscope, to he 

 uniniprcp^nat'^d, are really fertilized, hut scjj^nientation lias i)een 

 arrested as a result of the injuries received; in other words, they 

 have been killed. 



If we concede this theory to h.' true, it then follows tiiat 

 nianv of the ej^'j^s which we have t^enerally supposed to be unini- 

 preg'nated are really those where sei^-nientation has been stop])ed 

 through injury to the disc, and since in the case of the pike 

 perch egg this loss of ten runs u]) to one-fourth or even one- 

 third of the whole, it would seem that the remedy should be 

 sought in greater care in handling the eggs up to tlu' i)oint where 

 they are fully cushioned by the al:)Sorption of water. This view 

 was fully sustained at the Put-in-Bay station of the U. S. h'ish 

 Commission during the spawning season of icSgcj in the case ot 

 several lots of pike perch eggs taken by the station force from 

 the boats of the fishermen near by, brought to the station in the 

 milt and manipulated with great care on the floor of the hatching 

 room. These lots, embracing some twenty jars of eggs, hatched 

 out from 80 to 90 per cent of fry, and were by odds the best in 

 the house.
