measued about one fifth of an inch, and was also much 

 shrunk ; being now instead of a thick and fleshy 

 .mass only a thin and fibrous envelope. The green 

 film that formerly adhered to the inner surface of 

 the ovary, and was detached from it with difficulty, 

 is now perceptible even through the ovary, and 

 begins to adhere to the nucleus which is still a clear 

 fluid enclosed in its proper envelope, and not so 

 much globular in its figure as oval, tapering to a 

 small point at the base. 



On the 14th, when the ovary measured about 

 one fourth of an inch, the fluid of the nucleus was be- 

 ginning to be converted into albumen, within its 

 proper envelope, to which the green film adheres, 

 but from which, as well as from the ovary, it may 

 readily be detached though not always entire, being 

 of a very slender texture. Its colour is less de- 

 cidedly green, except at the furrow, where it origi- 

 nates in the umbilical cord. The embryo is not yet 

 perceptible. 



On the 20th, when the ovary had augmented 

 considerably in width, the length being as before, 

 end the nucleus had been converted almost entirely 

 into a soft albumen, the embryo was at last dis- 

 coverable in the base of the nucleus, but scarcely dis- 

 tinguishable into its several parts ; the whole mea- 

 suring only T V f an i nc h by T^ at the broadest part. 



On the 24th, when the seed was swollen to 

 nearly its full size, the three envelopes were still 

 very distinct. The outer envelope is what was the
