be lacking, as well as speculation concerning the origin of these remark- 
able formations.” 
It is unfortunate that Dr. Winner does not seem to be familiar 
with a paper on “The Papillary Ridges on the Hands and Feet of 
Monkeys and Men” which I contributed to the Royal Dublin Society 
on April 24th 1895, and which was published in the Scientific Trans- 
action of this Society with five quarto-page illustrations in September 
18951). Further, this paper was reviewed in „Nature“ November 14th, 
1895; and again reviewed in the Journal of Anatomy and Physiology 
for January, 1896. 
My object as stated in that paper was to “investigate the arrange- 
‘ment of the papillary ridges on the hands and feet of monkeys 
generally, in the hope that thereby I might be able to throw light 
upon any fundamental or ground plan which may determine the parti- 
cular patterns which Gatton has shown that these papillary ridges 
assume in the human fingers”. It is not necessary that I should now 
enter into the details of my investigation. Suffice it to say that I 
examined impressions of the hands and feet of six different species 
of living Primates. I discussed the association of papillary ridges with 
the sense of touch and also with the position occupied by the orifices 
of associated sweat-ducts. Further, I discussed the direction and 
arrangement of papillary ridges, in hands and feet and on the prehen- 
sile tails of certain monkeys and concluded that papillary ridges are 
intimately associated with prehension. 
Again, my paper drew attention “to certain distinct and practic- 
ally constant eminences on the flexor aspects both of the hand and 
foot of monkeys and men”. It goes on to state that, “In the hand 
these eminences are situated as follows: 
1) Opposite each phalanx, but especially the terminal phalanx, 
where each eminence develops in the form of a rounded pad. 
2) Three eminences situated in the palm above the clefts between 
the digits. 
3) The thenar and hypothenar eminences.” 
It will be seen that Dr. Winner adds to this list an accessory 
hypothenar which is also figured in one of my published plates 
but not described under that name. 
With regard to the question of these various eminences suggesting 
the “pads” of a pentadactylous foot, my paper drew “special attention
