386 LOTSY, CURRENT THEORIES OF EVOLUTION. 
an ancestor, who, speaking of a subject of which he had no accurate 
knowledge, played upon prejudice to evoke opposition against the 
results obtained by patient work and deep reflection by a high 
minded man and a great naturalist. 
I would feel very much the same in regard to an ancestor like 
Mr. Bryan, who although lacking in knowledge of even the rudiments 
of the doctrine of evolution, yet tries, and in one State almost 
succeeded, to suppress the teaching of it, or to one ofthe type of 
J. W. Porter, D. D., L.L D., who in his booklet „Evolution a 
Menace” states brazenly, that hybridisation can never have played 
a role in evolution, because, as everybody knows, mules are sterile! 
Yet, I prefer Dr. PORTER to MR. Bryan, because the dedication 
of his pamphlet has given me so much pleasure, as no doubt it 
will give you. 
It reads: 
„To my beloved and womanly wife, on whose brow is stamped,

has been plaintiff or defendant in 206 libel suits and won every 
one of them.” Possibly the opponents of Evolution are proud of 
this champion, [ am sure that all of us are glad that he is not on 
our side. 
I have only referred to this kind of litterature to emphasize the 
fact, that whatever object we observe in nature: climates, scenery, 
the bodies or the minds of plants or animals, including man, we 
find endless diversity. A similar diversity we meet with, when we 
proceed to a more detailed study of nature. 
In the Natural History Museum in New York, I saw a number 
of scallop shells (Pecten) taken from a peck, bought in the market, 
arranged according to the number of their rays, showing that, 
among scallops also, there is considerable diversity; the naturalist, 
responsible for this exhibition, however, does not refer to it as to 
a demonstration of diversity, but speaks of variation. 
Yet, there is not the slightest doubt, that what he found and
