 outlines may be absolutely trusted. The only improvements 

 that better prints could show would be in the details of individual 

 ridges, and other matters which, even in duplicate twins, are 

 individual, and without significance here. 



From a comparison of these four outlines (Figs. 27-30) it will be 

 seen at once that here is presented the unexpected ; that while three 

 of the four feet, as well as all four hands (presumably) conform

 three of the feet even the curious reduced hallucal pattern, an 

 extremely rare type, is faithfully reproduced, yet in the fourth, 

 the right sole of Mary, there is a radical departure from this 

 type, and a loop of the "A" type is presented instead, i. e., a 

 loop opening up between the first and second toes. Further-

 fourth and fifth toes; the presence of two lower triradii, quite 

 absent in the other three soles, are also to be detected. 



Taking up these two differences in order, the hallucal pattern 

 of the three feet which are alike is of the extremely rare type A C, 

 in which the two triradii a and c of the typical whorl are absent,
