Both Gartner and Kolreuter have proved that in genera of plants, including many species, a series can be formed from species which, when crossed, yield fewer and fewer seeds, to species which never produce a single seed, but yet are affected by the pollen of the other species, as shewn by the swelling of the germen.

It is here manifestly impossible to select the more sterile individuals, which have already ceased to yield seeds; so that this acme of sterility, when the germen alone is affected, cannot have been gained through selection; and from the laws governing the various grades of sterility being so uniform throughout the animal and vegetable kingdoms, we may infer that the cause, whatever it may be, is the same or nearly the same in all cases."
The stamina are six, with one stile, growing from the germen, which stands up in three brownish segments, resembling a cup. The trees grow from fifty to sixty feet high, with large, spreading, horizontal branches, almost as low as the earth. The root is said to contain much camphor that may be obtained by boiling or other processes unknown on Sumatra.

He has expressed a wish that some traveller would examine the milk of the papaw-tree just as it flows from the stem or the fruit. The younger the fruit of the carica, the more milk it yields: it is even found in the germen scarcely fecundated. In proportion as the fruit ripens, the milk becomes less abundant, and more aqueous.
I cannot conceive how the engages ever assimilated this animal with the buffaloe for there is not greater analogy than between the horse and the frog. this animal is found in greatest numbers in the sandy open parts of the plains, and appear in great abundance after a shower of rain; they are sometimes found basking in the sunshine but conceal themselves in little holes in the earth much the greater preportion of their time. they are numerous about the falls of the Missouri and in the plains through which we past lately above the Wallahwallahs. The Choke Cherry has been in blume since the 20th inst. it is a simple branching ascending stem. the cortex smooth and of a dark brown with a redish cast. the leaf is scattered petiolate oval accute at its apex finely serrate smooth and of an ordinary green. from 11/2 to 3 inches in length and 13/4 to 2 in width. the peduncles are common, cilindric, and from 4 to 5 inches in length and are inserted promiscuously on the twigs of the preceeding years growth. on the lower portion of the common peduncle are frequently from 3 to 4 small leaves being the same in form as those last discribed. other peduncles 1/4 of an inch in length are thickly scattered and inserted on all sides of the common peduncle at wright angles with it each elivating a single flower, which has five obtuse short patent white petals with short claws inserted on the upper edge of the calyx. the calyx is a perianth including both stamens and germ, one leafed fine cleft entire simiglobular, infrior, deciduous. the stamens are upwards of twenty and are seated on the margin of the flower cup or what I have called the perianth. the filaments are unequal in length subulate inflected and superior membranous. the anthers are equal in number with the filaments, they are very short oblong & flat, naked and situated at the extremity of the filaments, is of a yelow colour as is also the pollen. one pistillum. the germen is ovate, smooth, superior, sessile, very small; the Style is very short, simple, erect, on the top of the germen, deciduous. the stigma is simple, flat very short.
When Mr. Vanderpoel reached his office and glanced at his carefully arranged morning's mail, Mr. Germen saw him smile at the sight of the envelopes addressed in his daughter's hand. He sat down to read them at once, and, as he read, the smile of welcome became a shrewd and deeply interested one.
This had been the case even when she had just been placed in a French school, a tall, slim little girl, with immense demanding eyes, and a thick black plait of hair swinging between her straight, rather thin, shoulders. Between other financial potentates and their little girls, Mr. Germen knew that the oddly confidential relation which existed between these two was unusual.
It is here manifestly impossible to select the more sterile individuals, which have already ceased to yield seeds; so that the acme of sterility, when the germen alone is affected, cannot have been gained through selection.
