APPENDIX. 

 Sets of Quadruplets Inheriting Double Scutes from Unknown Fathers. 



Purely as a matter of record there is included herewith as an 

 appendix a pictorial tabulation of 31 sets of fetuses from normal 

 mothers but themselves with anomalies. There is every reason 

 to believe that these characters have been inherited from the 

 unknown fathers. There are 15 female sets and 16 male sets. 

 The same plan of representing the occurrence and location of 

 these double elements is followed as was used in the earlier tabu- 

 lation, the key to which is given on page 181. 



Since all of these cases are uniparental while many of the cases 

 discussed earlier are biparental, one would expect a simpler state 

 of affairs and fewer double scutes per set. This is actually the 

 case. The interrelations between the different fetuses of a set 

 are on the average much more clearly denned since there is no 

 confusing admixture of elements from both parents. These 

 facts go far to prove that the conclusions reached in the earlier 

 part of the paper regarding modes of inheritance are well 

 founded. 



Many striking cases are seen of close resemblance between 

 twins, of mirror-imaging and half-band reversals between twins, 

 all of which reinforce the conclusions reached on the basis of the 

 data heretofore discussed. Nothing, however, would be gained 

 by calling further attention to individual cases. The interested 

 reader will be able to pick out and classify for himself the various 

 types of anomaly. The pictorial method of recording these 

 elements may need a little study on the part of the reader but is 

 fully justified by the fact that a large amount of valuable data, 

 the like of which may never again be available, is given in very 

 compact form. 



Correction. On page 27 of the first installment of this study 

 (Newman '15) is figured the double band arrangement in set K 2. 

 This set was classed erroneously among sets the mother of which 

 had no anomalies. The notebook in which the data was taken 

 shows the mother of K 2 was misplaced and later found and has 

 two anomalies. Band 3, which has 64 scutes, has a double scute, 

 like Fig. 2a, 16 places to the right of the middle. Band 5 (63
