Also by mutual crossing of New Spread individuals we get a 
proof of these individuals behaving otherwise than the original 
ones, for in accordance with what was theoretically expected they 
give 2 Spread: 1 normal, as appears from table IV, where the 
crossings in question are gathered.

Finally a culture (K. 56) gave the following result: 77 Spread 
(47 99 + 30 47) and 80 normals (43 99 + 37 LL) 
Of the last mentioned crossings only this one (K. 56) gave an
