Mr. Francis Galton on 
Note : — The question is not asked now whether such 
peculiarities^ or ^' sports/' may be accounted for 
by atavism or other hypothetical causes. 
(3) Instances in which any of these peculiarly charac- 
terized individuals have transmitted their pecu- 
liarities^ hereditarily, to one or more generations. 
Especial mention should be made whether the 
peculiarity was in any case transmitted in all its 
original intensity, and numerical data would be 
particularly acceptable that showed the frequency 
of its transmission (a) in an undiluted form^ (h) 
in one that was more or less diluted_, and (c) of 
its non-transmission in any perceptible degree.* 
It is impossible to explain to a general meeting the 
precise way in which the desired facts would be utilized. 
An explanation that would be sufficiently brief for the 
purpose could not be rendered intelligible except to those 
few who are already familiar with the evidence, and the 
technical treatment of it_, by which the law of Regression 
is established and with the consequences and require- 
ments of that law. Reo^ressiveness and Stability are 
contrasted conditions, and neither of them can be fully 
understood apart from the other. 
I may as well take this opportunity of appending a 
list of my various memoirs on these subjects. They 
appeared from time to time in various forms as the 
inquiry progressed, and as suitable openings occurred for 
writing or speaking. The more important of these are 
Nos. 1, 3, part of 6, 7, and 8, in the following list. 
Nos. 1 to 5 refer to Regression only. The whole are on 
the table in two volumes, the loose memoirs being bound 
together to form one of them, and Natural Inheritance 
being the other. I hope that the Society will do me the 
honour of accepting these^ and keeping them in their 
library.

Gate, London, S.W.
