SUPPOSED “IDENTICAL” TWINS 
The only measurable difference between these two young Irishmen is an 
inch in height; if they are separated few people can tell one from the 
other. Their commanding officer was obliged to put them in separate 
companies, and even then did notavoid frequentembarrassments. Their 
finger prints, as shown in the following illustration, are remarkably 
similar but not identical: a fact which may be taken to show that 
heredity governs the main outlines but nct all the details of the 
finger pattern. Photograph from J. H. Taylor. (Fig. 18.)
