CONTENTS OF VOL. I. XV 



— Relation of organisms to energy and to matter — Energy is assimilated — 

 General statement — Death followed by chemical transformations— Chemical 

 action during life — Transformation of vital energy in death, and in disease — 

 Analogy of life to magnetism — Summary — Dependence of development on heat 

 — Transfonnation of energy in organic development — Energy of life depends 

 on the supply of oxygen — The most highly organized plants and animals are 

 air-breathers — Larva and perfect form. 

 Note : On the Relation of Muscular Action to Heat: — Cold produced in muscular 

 action — Parallel fact in thermo-electricity — These cases are exceptional. 



Pp. 90—109 



CHAPTER X. 



ORGANIZATION. 



Three kinds of formative principles ; the fii-st forms spherical aggi-egatious — 

 Agate nodules, having structure depending on form — Hailstones — Second kind, 

 producing ciystals, having forms depending on structure — Third kind, producing 

 orgauisms — Organization inexjilicable — Life is the cause of organization — Or- 

 ganic germs are without structure, as are some mature organisms — Germinal 

 matter has no structiire — Crystallization and Organization — Reaction of formed 

 on unformed material — Organization defined — Three relations in science : cause, 

 resemblance, purpose — Sciences of cause — Chemistry — Sciences of resemblance, 

 or classificatory sciences — Crystallography — Biology — Morphology — Importance 

 of classification — Its basis in fundamental characters — No rule possible — Fun- 

 damental characters in chemistry, crystallography, and biology — Morphology 

 — Physiology — Purpose in creation peculiar to organization : has analogies in 

 man's work — Organic structure implies function — Is this relation a case of 

 that of cause and effect ? — I believe not — Purpose is more traceable, and cause 

 less so, as we ascend in nature — Purposes in organization are only relative — 

 Final cause, an inaccurate expression — Organic adaptation implies intelligence 

 — Purpose not discoverable in the inorganic creation . . . . Pp.110 — 124 



CHAPTER XI, 



ORGANIC DEVELOPMENT. 



Development consists in the acquisition of structure by a structureless germ — 

 Histology is the science of tissues ; anatomj', of organs — Repair of injuries a 

 case of development — Germinal matter is without structure — Fonned material 

 cannot be further transformed — Gromia— Larvse of Echinoderms — Cells — Cel- 

 lular tissue — Sarcode — White blood-corpuscles — Why the higher organisms do 

 not live when cut in pieces — Propagation by spontaneous division, and by bud- 

 ding — Separate generative organs in the higher classes — Origin of species : is 

 it also by development from simple germs, through descent with modification ? 

 — I believe so^Deviations from strict logical method —Origin of species, and 

 origin of life, distinct questions Pp. 125 — 131
