Σελίδα 210 - I think I may fairly make two postulata. First, That food is necessary to the existence of man. Secondly, That the passion between the sexes is necessary, and will remain nearly in its present state.
Σελίδα 136 - It is at once apparent from this table that there is a profound and regular change in the rate of reproduction of Drosophila, under the conditions of these experiments, with increasing density of population. The rate of reproduction per mated female per day declines as density of population increases, at first extremely rapidly and then more and more slowly at higher densities.

Σελίδα 22 - In the matter of population growth there not only " ought to be a law " but six years of research has plainly shown that there is one.

Σελίδα 210 - London, 1928, p. 54. people on this globe which the biological law of population growth makes extremely probable, lead us to view-with-alarm ? It seems to me that if we so conclude, we ought equally to be concerned about the orderly growth of any baby into man- or womanhood.
Σελίδα 22 - ... until the mid-point of the cycle is reached. After that point the increment per unit of time becomes steadily smaller until the end of the cycle. In a spatially limited universe the amount of increase which occurs in any particular unit of time, at any point of the single cycle of growth, is proportional to two things, viz: (a) the absolute size already attained at the beginning of the unit interval under consideration, and (b) the amount still unused or unexpended in the given universe (or area)...
Σελίδα 238 - Rapport fait au nom de la Commission chargée d'examiner les modifications à introduire dans la législation et dans l'organisation des divers services de l'Algérie.
