1. The Terms of Bioplastology. 
By Professor A. Hyatt, Boston, Mass., U.S.A.

Ontogeny. 
Messrs. Buckman and Bather have proposed to substitute a 
set of improved terms for those previously used by myself and both are

Ontogenic Table of Terms (I). 
Hyatt 1888. Buckman and Bather 1892, 
1) Embryologie 1) Embryonic 1) Embryonic 
2) Naepionic 2) Brephic 2) Infantile or Larval 
3) Nealogic 3) Neanic 3) Adolescent 
4) Ephebolic 4) Ephebic 4) Adult or mature 
5) Geratologie 5) Gerontie 5) Senile

b) Nostologie b) Hypostrophie b) Atavie
