“Darwin spent the twenty years subsequent to the publication of the Origin of Species, as he had spent the preceding twenty years, in study and research, the results of which appeared in nine additional volumes. Three of these perhaps may be singled out as primarily an elaboration of the Origin: {{w|The Variation of Animals and Plants under Domestication}} (1868), The Descent of Man (1871), and {{w|The Expression of the Emotions in Man and Animals|The Expression of the Emotions}} (1872).”

“The earliest clear appreciation of the importance of studying living nature with {{w|Scientific instrument|instrument}}s which increase the powers of the senses in general and of vision in particular, is found in a remarkable book, the Micrographia of Robert Hooke (1635-1703), published by the {{w|Royal Society|Royal Society of London}} in 1665, which is a demonstration of the advantages to be gained by the use of artificial devices of precision.”

“With the work of {{w|Valerius Cordus|Cordus}}, Vesalius, and Harvey, {{w|biologist}}s had again laid hold of the great scientific tools—observation, experiment, induction—which since have not slipped from their grasp.”

“{{w|Protein|{{small-caps|Proteins}}}} invariably consist of the elements {{w|carbon}}, oxygen, {{w|hydrogen}}, {{w|nitrogen}}, and sulfur, and frequently {{w|phosphorus}} and iron. Examples are {{w|Albumin|{{small-caps|albumin}}}} of the {{w|Egg white|white of egg}}, {{w|Casein|{{small-caps|casein}}}} of milk, {{w|Gluten|{{small-caps|gluten}}}} of {{w|cereal}}s, and {{w|Myosin|{{small-caps|myosin}}}} of lean meat.”

“{{w|Paramecium|Paramaecia}} excrete substances which are toxic to themselves when present in their environment, and these substances are more effective when the organisms are confined in limited volumes of {{w|Microbiological culture|culture}} fluid.”
