subdivisibility of each individual into many distinct units or traits,

various individuals of the family line, and not to one individual alone

and later discoveries by a number of other scientists, revealed the
subdivisibility of each individual into many distinct units or traits,
the hereditary sources of which were clearly traceable, leading to

Furthermore, it was found that the lack of a certain trait sometimes
appears as a trait in itself, just as darkness seems like a condition in
itself rather than as an absence of light.

Scientists are universally agreed as to the wisdom of the

adoption of the metric system
Scientists are universally agreed as to the wisdom of the
adoption of the metric system. The country, as a whole, must be
educated up to the notion that sooner or later it is sure to be
universally adopted, that it is only a question of time when
this will be done. Already electrical, chemical and optical
manufacturing concerns use the metric units and system
exclusively. The system is also used widely in medicine and
still other arts. Then all institutions of learning use the
metric system exclusively whenever this is possible. All that
is needed is to complete a good work well begun.

The ordinary man, in ordinary good health, does not want or thinks he

does not want to live hygienically
The ordinary man, in ordinary good health, does not want or thinks he
does not want to live hygienically. He sees all sorts of imaginary
objections to adopting a hygienic life, and closes his eyes to its real
and great advantages. One of the objections often trumped up is that the
practise of hygiene costs too much--that it can only be a luxury of the
rich. It is quite true that here, as elsewhere in human life, wealth
confers great advantages. The death-rate among the rich is always less
than that among the poor. And yet the rich have unhygienic temptations
of their own, while the poor, on their part, are far from living up to
their opportunities.

The problem of species has profoundly changed since 1859

The problem of species has profoundly changed since 1859. For
Darwin it was perforce a problem of adaptation. For the
investigator of to-day it has become a part of the more
inclusive problem of variation. Along with the logical results
of natural selection he contemplates the biological processes
of organic differentiation. He is no longer satisfied to assume
the existence of those modifications that make selection
possible. In his efforts to control them, the conception of
adaptation as a result has been crowded from the center of his
interest by the conception of adaptation as a process.
