 whether the seed had been drawn 

 upon for nutriment; but the next 

 drawing — which gives a good view 

 of the collar — does not suggest it. 



There was no sign of shrinkage 

 that I could see. Nor does a 

 close examination of its internal 

 economy lend colour to botanical 

 opinion, though I do not pretend 

 to question it.

The development exhibited in 

 Figures 76 and 77 is deserving of 

 attention. The collar is well de- 

 fined and springs from the seed 

 substance at a point just above 

 the round lighter disc, which point 

 identifies itself with the dumb-bell 

 like protuberance always to be seen 

 in this seed when it is cut in section. 

 Furthermore, we now see that while 

 the growth has been outward, an 

 inward change has taken place; 

 the wings of the collar extending 

 around the sides of the seed. In 



the centre of the seed was a loose piece which is shown in. 



the accompanying Figure : but which, as it fell out upon 



being handled, is probably not concerned with growth. 



When it did so the seed appeared as foUows :
