[Physiology will be treated as a sepax'ate science. In Zoology 



it is therefore only necessary to collect those physiological 



memoirs that specially interest zoologists ; hence a detailed 



division is superfluous, but the following may be cited as 



examples to come under this heading.] 



General ; Parthenogenesis ; Pedogenesis ; Dissogony ; 



Hermaphroditism; Production of Sex; Production 



of Caste ; Function of Sense Organs ; Function of 



Special Structures, e.g., of Glands; Environmental 



Effects ; Regeneration ; Change of Function.
