  • One of Harvey's prime objects is to defend and establish, on the basis of direct observation, the opinion already held by Aristotle, that, in the higher animals at any rate, the formation of the new organism by the process of generation takes place, not suddenly, by simultaneous accretion of rudiments of all or the most important of the organs of the adult, nor by sudden metamorphosis of a formative substance into a miniature of the whole, which subsequently grows, but by epigenesis, or successive differentiation of a relatively homogeneous rudiment into the parts and structures which are characteristic of the adult.

  • The centre of Florence, which was becoming a danger from a hygienic point of view, was pulled down in 1880-1890, but, unfortunately, sufficient care was not taken to avoid destroying certain buildings of historic and artistic value which might have been spared without impairing the work of sanitation, while the new structures erected in their place, especially those in the Piaza Vittorio Emanuele, are almost uniformly ugly and quite out of keeping with Florentine architecture.
