keep it from degenerating in its power 
capabilities. In Dynamic Evolution® I 
have given detailed explanations of how 
acquirements are measured, how the 
standard for any group of animals is 
determined, and how comparisons are 
made. Also some peculiarities of the 
manner in which acquirements are 
transmitted to succeeding generations. 
THREE GENERATIONS REQUIRED 
“T now make an additional money 
offer for contrary evidence bearing on 
this matter, the understanding being 
that measurements must be in dynami- 
cal units, must be reasonably accurate, 
and must extend over three generations 
of ancestors, or so much thereof as will 
leave no doubt whatever as to what the 
measurements for three generations 
will say. 
“1. I have given detailed accounts of 
large numbers of cases in which im- 
provement in mental and_ physical 
powers followed excess acquirements in 
previous generations. I will give $200 
for any case in which improvement 
followed acquirements below _ the 
standard. 
‘2. I have given the details of many 
cases in which a decline in powers fol- 
lowed acquirements less than the 
standard. I will give a second $200 for 
any case in which a decline in powers 
failed to follow acquirements which 
were clearly and distinctly less than the 
standard. 
“3. By taking large numbers of ani- 
mals I have shown that the amount of 
improvement or decline in animal pow- 
ers was, as nearly as could be determined 
by the measurements, exactly propor- 
tional to the amount of acquirement 
by ancestors above or below the normal 
or standard. I will give a third $200 if 
any group of animals is found for which 
this is not true. 
“The aggregate of these offers is 
$1,000, and they extend to December 
31, 1916. If the $1,000 is not captured 
it will not be because there is any lack 
of material from which the matter may

be tested, or any difficulty in doing the 
necessary work. Published pedigrees 
and histories of men, horses, dogs and 
cattle furnish all of the evidence neces- 
sary for a complete investigation, and 
the mathematics involved is of the 
simplest kind. 
“Men of great ability arise from 
common stock; many horses of the 
present day trot much faster than any 
horse was capable of trotting fifty years 
ago; cows frequently produce many 
more pounds of milk in seven days than 
was the utmost capability of any of 
their great-granddams, and dogs under 
tests in field trials show more ‘class’ 
than any of their ancestors. The claim 
is made that every case of this kind 
arose by the inheritance of excess de- 
velopment acquired before reproducing, 
and that it is impossible to increase the 
mental or physical powers of any kind 
of animal in any other way than by the 
inheritance of such acquirements. If 
any one can show the contrary he can 
capture my money. 
DETAILS TO BE PUBLISHED 
“The American Genetic Association, 
or its accredited representative, shall 
be judge in this matter, and if the money 
is captured the judge shall say to whom 
it shall be paid and how paid. It is 
expected, in case the money is captured, 
that the judge will publish his findings 
in the case, giving full details of the 
evidence upon which the decision is 
based. 
“In this connection I will offer the 
following for consideration: According 
to the current theory of evolution, there 
was, some time in the past, a common 
ancestor for man and the higher apes. 
There have been less generations, and 
consequently there has been less selec- 
tion, in the line leading from that com- 
mon ancestor to man, than in the lines 
leading to the apes. Further back in the 
past there was a common ancestor for 
the higher apes and the lower monkeys. 
There were less generations, and con- 
sequently less selection in the lines
