lays stress upon the fact that the most advanced sciences have attained to their present power by a slow process of improvement, extending through thousands of years, that science and the positive knowledge of the uncultured cannot be separated in nature, and that the one is but a perfected and extended form of the other. "Is not science a growth?" says he, "Has not science its embryology? And must not the neglect of its embryology lead to a misunderstanding of the principles of its evolution and its existing organization?" It seems to me unfortunate, therefore, that we should allow the value of the labors of our predecessors to be depreciated, or to refer to the naturalists of the last century as belonging to the unscientific or to the archaic period. It has been frequently said by naturalists that there was no science in America until after the beginning of the present century. This is, in one sense, true, in another, very false. There were then, it is certain, many men equal in capacity, in culture, in enthusiasm, to the naturalists of to-day, who were giving careful attention to the study of precisely the same phenomena of nature. The misfortune of men of science in the year of 1785 was that they had three generations fewer of scientific predecessors than have we. Can it be doubted that the scientists of some period long distant will look back upon the work of our own time as archaic and crude, and catalogue our books among the "curiosities of scientific literature?" Is it not incumbent upon workers in science to keep green the memory of those whose traditions they have inherited? That it is, I do most steadfastly believe, and with this purpose I have taken advantage of the tercentenary of American biology to read this review of the work of the men of old. Monuments are not often erected to men of science. More enduring, however, than monuments are those living and selfperpetuating memorials, the plants and animals which bear the names of the masters who knew them and loved them. Well have the Agassizs remarked that there is a world of meaning hid 66 den under our zoölogical and botanical nomenclature known only to those who are intimately acquainted with the annals of scientific life in its social as well as its professional aspect."* I hope I am not at this day entirely alone in my appreciation of the extreme appropriateness of this time-honored custom, although I know that many of our too matter-of-fact naturalists are disposed to abandon it, and that it is losing much of its former significance. In fact, in these days of unstable nomenclature, such tributes are often very evanescent. It seems fortunate that the names of some of the most honored of the early naturalists are perpetuated in well established generic and specific combinations.† When I see the Linnæa borealis, I am always reminded of the sage of Upsala, as he is represented in the famous Amsterdam painting, clad in Lapland fur, and holding a spray of that graceful arctic plant. Magnolia and Wistaria call up the venerable prófessors of botany at Montpelier and Philadelphia. Tradescantia virginica reminds me of John Tradescant and the Ashmolean Museum, whose beginnings were gathered by him in Virginia.

The genus HARRIOTTA has been dedicated by Goode and Bean to the memory of Thomas Harriott. It is intended to embrace a long-rostrated chimæroid fish from deep water off the Atlantic coast of North America. The description is not yet published. "Heriot's Isle," named for Harriott by the early explorers, and shown upon Vaughan's map, in Smith's "Generall History of Virginia," has entirely disappeared. It was situate on the north side of Albemarle Sound, about midway between Roanoke Island and the mouth of Chowan river. Whether it has been swept away by the tides, or has become a part of the main-land, it is difficult to say. The latter supposition seems the most probable, and since it is in all likelihood "Reed's Point" which now occupies its former location. the propriety is suggested of calling this little cape, Harriott's Point," in memory of the explorer. lictrum and Asclepias Cornuti, Macrurus Fabricii, Didelphys and Canis Azaræ, Chauliodus Sloanei, Alutera Schopfii, Sterna, Forsteri, Stolephorus Mitchilli, Malacanthus Plumieri, Salix Cutleri and Pinus Banksiana, the Kalmia, the Jeffersonia, the Hernandia, the Comptonia, the Sarracenia, the Gaultheria, the Kuhnia, the Ellisia, the Coldenia, the Robinia, the Banisteria, the Plumieria, the Collinsonia, the Bartramia, all bear the names of men associated with the beginnings of Natural History in America. Yet, pleasant as it is to recall in such manner the achievements of the fathers of natural history, let us not do them the injustice to suppose that posthumous fame was the object for which they worked. Like Sir Thomas Browne, they believed that the world was made to be inhabited by beasts, but to be studied by man." Let us emulate their works and let us share with them the admonitions of the " Religio Medici." "The wisdom of God," says Browne, "receives small honor from those vulgar heads that rudely stray about, and with a gross rusticity admire his works; those highly magnify him whose judicious inquiry into his acts, and deliberate research into his creatures, return the duty of a devout and learned admiration. Therefore," he continues "Search while thou wilt and let thy reason go ADDITIONS TO THE FLORA OF WASHINGTON AND VICINITY, FROM APRIL 1, 1884, TO APRIL 1, 1886. By F. H. KNOWLTON, B. S.

The species added to the Flora between April 1, 1884, and April 1, 1885, were enumerated by Prof. Ward in a paper read before the Society Dec. 13, 1884; the additions and changes for 1885 were presented by the author in a paper read March 20, 1886.

Specimens of this plant have been sent to Dr. Asa Gray, who states that he considers this form to be the type, and that the original specimens col 106 lected by Curtiss were abnormal. Until an authoritative revision of the genus is made, however, it must stand as above. 195a. Trifolium hybridum, Savi. Alexander's Island, June 25, 1885, by Mr. J. A. Allen. 295a.
