that we have less liberty now than our fathers had three centuries
ago; progress never stops, and each day is something gained; but it
seems clear that the juridic basis and form of our liberties have
not kept up with the progress of those very liberties. Yet, what we
call rights must have a counterpart or reflection in our laws. We may,
while enjoying those rights, forget that the juridic basis on which
they stand is crumbling with age. Unless that basis is rejuvenated the
entire edifice must eventually fall. While we are in full possession of
our rights we need no laws to guarantee them; but it is when those laws
are encroached upon that there arises the necessity of juridic sanction
for them.
The right of life, liberty, and property constitutes the essence of
the “law of the land.” But the conception of rights, as we have seen,
changes and progresses. The law of the land must likewise change and
progress.
Laws may be the highest and best creation of man’s intellect, but they
are not “hedged in by any divinity.” That is why they are neither
infallible nor unchangeable. Yet, as the highest and best creation of
man’s intellect, and as the final criterion of human public conduct,
they should conform to the best thought and to the highest scientific
progress. If they do not approach this standard they are worse than
useless, for they become legalized means of oppression. It is then that
Justice needs a bandage over her eyes, not to avoid partiality, but to
hide her shame.
THE BLIND FISHES OF NORTH AMERICA.
BY CARL H. EIGENMANN,
PROFESSOR OF ZOÖLOGY, INDIANA UNIVERSITY.
“An investigation into the history of degenerate forms often
teaches us more of the causes of change in organic Nature than can
be learned by the study of the progressive ones.”--WEISMANN.
The caves of the United States are inhabited by three cave salamanders,
two of them with degenerate eyes; by six cave fishes, all with impaired
vision--five of them with rudimentary eyes, one with eyes the most
degenerate among vertebrates; and by several mammals. It is thus seen
that among the interesting features of the North American fauna the
blind vertebrates are not the least. Yet during the past twenty-five
years the only additions to our knowledge, aside from diagnoses of new
species, have been a few random notes on the habits and a short account
of the eye of Troglichthys by Kohl.
Various classes of vertebrates have blind members, but no large
vertebrate has become blind or permanently taken up its home in caves.
Blatchley reports that a number of cats have established themselves
in Wyandotte Cave, where they bring forth and rear their young. They
have exterminated the cave rats, and now station themselves in a narrow
passage of the cave and capture bats as they fly through.
