(In apterous insects a rudiment of wing – In man a rudiment of tail – a rudiment may be more developed as canine teeth in deer Zoolog Proc vol 1836-41 p. 4. (In genera allied to Penstemon occasional appearance of 5th stamen???

Very important to pure long inheritance of tendency. Why surprised when we see long inheritance of rudimentary organ, & ever long inheritance of tendency of rudiment to be developed.
