would be practical to have it enclosed in a bag of usual fishing 
net — e. g. also for the case that it should be too full of mud or 
sand, so that it would be in danger of breaking. It might further be 
practical to have the frame of the silknet attached to the plates 
by means of a spring, instead of tying it with a string, so that it 
might easily be lifted up, which would facilitate both the sifting 
of the material and the changing of the net. — These are, however, 
all minor points. The main thing is the general system here used. 
I venture to think that this really means a practical solution of 
the problem of catching the micro-fauna of the sea-bottom.
