all four are practically alike, and that they conform in both partic- 

 ulars given above to the condition found normal in twins of the du-

 or emerge below it, that is, assume positions 5, 4, or 3. This 

 will give the formula 8 -6- 5 -5, with a possible variation in the 

 last term. The correctness of this surmise can be readily tested 

 as soon as the little girls are old enough to assist in the printing. 

 The prints of the feet, taken as they were, were necessarily

 out all the essential details, and it is from these that the outlines 

 here given were taken. As the photographs were taken by a
