The Independent says: "Those who contend for the continual appearance of new species on the earth derive much aid in their argument from the evident continual disappearance of old ones. It would not be consistent with our idea of the new creations unless it was evident that they succeeded extinct forms ; nor is it in harmony with all we know of nature to conceive of continual extinction unless we admit new forms appear to continue the work of nature. Among plants it is not uncommon to find some species so rare that but a few specimens are known to exist. These are often found in localities wide apart, and, as they must have in former times been more closely connected, but show no indications of connections now, they are regarded as species on the highway to the grave. In the Southern Alleghany regions are many of these disappearing forms, and there are quite a number in the North. Corema Conradii, a curious plant, with the habit of an Erica, but belonging to the order Empetracese, is an illustration. Turrey and Knieskern found it in New Jersey, but it has not been since seen where they discovered it. It was also once found on Long Island, but has disappeared from there.

A few plants have been found at Cape Cod, at Bath in Maine, and in Newfoundland. No doubt there may be a few more isolated places where it may yet be found. Recently Mr. Aubrey H. Smith, a Philadelphia botanist, has announced the discovery of a few plants in the Palmaghatt Pass, of the Shawangunk Mountains, in New York. The wide distribution of the localities show that the plant in the long ages past had a wide range, and its disappearance in the intervening spaces was wholly the work of natural agencies, and probably long before even the Indian existed on this continent.
