Seite 344 - Harvard College pays me for doing what I would gladly pay it for allowing me to do. No professional man, then, thinks of giving according to measure. Once engaged, he gives his best, gives his personal interest, himself.

We deplore the persistent misrepresentation of these aims, achievements, and procedures by those who are opposed to this scientific method. We protest against the frequent denunciations of self-sacrificing, high-minded men of science who are devoting their lives to the...
Seite 159 - Perfect growth and development implies a far-reaching correlation of the various parts of the body. An upset in this nicely balanced relationship is speedily recognized as an anomaly. Energy and matter are insufficient to explain the consummation and maintenance of a normal as contrasted with an abnormal composition of the cells. The specificity of growth is something marked, particularly when normal is contrasted with perverted growth. The definition referred to above has a particular value in the...
Seite 172 - during the normal development of the young of the same age and species, a definite percentage of the food is retained for growth irrespective of the size of the individual.
