*In this experiment the e<rgs of six or seven salmon, one fish at a time, were t.iken successively in 

 a drj" pan, and as soon as impregnated, each pan of eggs was poured into a bucket of water. This, if 

 I am rightly informed, is a method of taking salmon eggs used in Canada. Its advantage is that it 

 saves multiplying pans, one being sufficient for a season's spawning.
