An examination of the preceding table will show that the 
eggs are nearly, if not quite as easily killed, as the mites. It 
is possible that the eggs are more protected by the scabs than 
the mites, but in all the above experiments mites and eggs were 
treated alike on the wool and seem to have been killed about 
equally well. 
It seems strange that in the use of Black Leaf all of the 
eggs should have hatched that were taken from a sheep twenty- 
four hours after dipping, and nearly all should have been killed 
that were treated in the laboratory. 
* This lot was kept on an outer window sill.
