was a white and fleshy mass, but slightly tinged 

 with green where it invests the contained globule, 

 which is now more viscid. 



On the 2Oth, when the spike was completely ex- 

 tricated, the anthers were beginning to change to 

 yellow. They were now about one sixth of an inch in 

 length and the filaments twice as long. Some of 

 them had shed their pollen, of which thousands of 

 particles were found adhering to the expanding 

 styles. The nectaries were somewhat shrunk at the 

 base. The ovary exhibited more of green on the 

 inner surface. ' The enclosed globule or chorion was 

 as before. 



On the 2Qth, when the pollen was shed and the 

 styles beginning to fade, the nectary scales were 

 much shrunk. The ovary, now ^ of an inch in 

 length, was thick and less fleshy in its contexture. 

 The green substance is a film lining its interior sur- 

 face. The enclosed globule somewhat enlarged. 



On the 6th of July, when the ovary measured one 

 eighth of an inch and had assumed an oblong figure, 

 the green film was detachable from its inner surface, 

 seeming to be formed of an expansion of the umbi- 

 lical cord. The enclosed globule measured -^ of an 

 inch, and was now separable into an envelope and a 

 thin and colourless fluid, into which the jelly-like 

 substances of the former stages had been converted. 

 Perhaps this should now be called the amnios. 



On the 10th, when the nectaries were now shrunk 

 into thin scales fringed with hairs, the ovary
