 involving $ iV 19 are less extensive and may be considered first. Six

Fig. 2. Graphic representation of weight distribution in Fj and F2 generations from the 

 Flemish-mixed cross, ? iSTlQ x <? iV 169. The numbers above each of the columns 

 separated by broken lines denote lbs. Each black circle represents an individual and 

 is placed according to the weight of the individual in lbs. and oz. The record number 

 of those rabbits which have been mated together is given, cf. Tables I and II, 

 pp. 21—22. 



1 Considerable numbers of animals involving these three breeds were reared by me 

 between 1907 and 1912, I do not recall any marked differences in size. The great 

 majority, if not all of them, were probably between 5 and 7^ lbs. E. C. P.

 the maximum attained during the first twelve months (cf. p. 7).
