Strona 125 - ... the art of directing the great sources of power in nature for the use and convenience of man, as the means of production and of traffic in states.
Strona 91 - ... the succession of varieties comes to pass by the elevation and establishment of sporadic groups of individuals owing their origin to such isolated events ; and that the change which we see as a nascent variation is often, perhaps always, one of loss. Modern research lends not the smallest encouragement or sanction to the view that gradual evolution occurs by the transformation of masses of individuals, though that fancy has fixed itself on popular imagination. The isolated events to which variation...
Strona 90 - As I have said already, this is no time for devising theories of Evolution, and I propound none. But as we have got to recognise that there has been an Evolution, that somehow or other the forms of life have arisen from fewer forms, we may as well see whether we are limited to the old view that evolutionary progress is from the simple to the complex, and whether after all it is conceivable that the process was the other way about.
Strona 90 - I have confidence that the artistic gifts of mankind will prove to be due not to something added to the make-up of an ordinary man, but to the absence of factors which in the normal person inhibit the development of these gifts. They are almost beyond doubt to be looked upon as releases of powers normally suppressed. The instrument is there, but it is
Strona 146 - College of Science supplies, as far as practicable, a complete course of instruction in science applicable to the industrial arts...
Strona 87 - Naturalists may still be found expounding teleologica systems* which would have delighted Dr. Pangloss himself, but at the present time few are misled. The student of genetics knows that the time for the development of theory is not yet. He would rather stick to the seed-pan and the incubator.
Strona 144 - In the case of a student, whose, native language, is other than European, the Senatus may accept as an alternative to Latin or Greek any other classical language, such as Sanskrit or Arabic, Subject always to the provisions of Section IV., Sub-section 3 hereof.
Strona 222 - Heat the liquid containing the lead vanadate precipitate on the steam bath for one hour or more, filter on a tight filter, and wash with warm water. Dissolve the precipitate in the least possible quantity of hot dilute nitric acid, neutralize as before, add 3 cc of nitric acid in excess, add 2...
Strona 135 - To give the highest specialised instruction, and to provide the fullest equipment for the most advanced training and research in various branches of science, especially in its application to industry.
Strona 99 - Genetic research will make it possible for a nation to elect by what sort of beings it will be represented not very many generations hence, much as a farmer can decide whether his byres shall be full of shorthorns or Herefords. It will be very surprising indeed if some nation does not make trial of this new power. They may make awful mistakes, but I think they will try. Whether we like it or not, extraordinary and far-reaching changes in public opinion are coming to pass.
