A. PROPOSITIONS BELONGING TO THE DOMAIN OF PHYSIOLOGY
II.—Heat, from whatever source it may be derived, is the first and most important of all stimuli; and, when it ceases to exert its vitalizing power upon the economy, all other stimuli lose their power to produce any effect upon it.
IV.—If heat is withdrawn for a certain period of time all those phenomena of the economy which are of a conservative, reparative or medicative nature cease all activity; and the same is true when oxygen is withdrawn.
XX.—Assimilation, which is a phenomenon of the very first order, cannot be explained by the assumption that it is due to the action of sensibility and contractility; it should be looked upon only as a manifestation of a creative force,—as an act of vital chemistry.
XLII.—Instinct consists of nervous impulses or stimuli—sometimes associated with consciousness and sometimes not—which originate in one of the viscera, and which call upon the central nerve power to execute such acts as are necessary to the exercise of the functions of that viscus.
XLIV.—Acts which are originated by instinct are most frequently observed in infants, and are witnessed with diminishing frequency as the child’s intelligence becomes more perfect.
XLVII.—As may be said with equal truth of insanity the passions furnish an example of the triumph of the viscera—that is to say, of instinct—over intelligence; and, on the other hand, it is well-known that the passions themselves produce insanity.
LI.—The intellectual faculties may be exercised without any participation of passion, but never without an accompaniment of either pleasure or pain.
LXIV.—An excess of haematosis or sanguification in an organ increases at first the sum total of its vitality, but this increase is subject to limitations. If, for example, the excitation is kept up beyond a certain length of time the continued hyperaemia establishes in that organ a condition which deserves to be called disease.
