In spelling, usage wavers between -in and -ine. In chemistry a certain distinction of use is attempted, basic substances havingthe termination -ine rather than -in (aconitine; aniline, etc.), and -in being restricted to certain neutral compounds, glycerides, glucosides, and proteids(albumin; palmitin, etc.), but this distinction is not always observed |
