of the normal bands]. Some experiments concerning the heredity of 
the number of the bands, made by 0. Arndt. If both parents have 
similar bands, or no bands, about half the offspring exhibit the same 
bands, the other half disagreeing in a different direction ; the former, 
breeding between themselves, yield an increasing heredity, 77 per cent, 
agreeing with their parents and grandparents. Arch. Ver. Me3klenb-
