Excerpt from Science Progress in the Twentieth Century, 1908-1909, Vol. 3: A Quarterly Journal of Scientific Work and Thought

It is generally assumed in biological textbooks and lectures that, apart from the mode of alimentation exhibited by the internal parasites, all animals feed in much the same way as is witnessed in the higher terrestrial forms. Food organisms are captured and ingested, and digestive processes proceed in the alimentary canal in much the same manner as in the case of the mammal, that is, proteid food substances are hydrolysed, absorbed, and reconverted into the proteid substances specific to the Species considered; carbohydrates are hydrolysed to form diffusible sugars; and fats are saponified. Further, the current metabolism is usually regarded as similar to that of the warm blooded animals; that is, energy is obtained from the oxidation of part of the tissue substance; carbon dioxide and water being excreted, along with certain nitrogenous residues; that the amount of oxygen absorbed in respiration is nearly equal to the oxygen which is present in the excretory products; and that a fairly constant respiratory quotient is the result of the metabolism of the animal.
