    CEDAR HILL, ASHLEY RIVER. Dec. 15th, 1849.—At Mr. Dwight’s plantation, (Cedar Hill,) I found growing abundantly on stems of grasses in the river, Bostrichia scorpioides and Deles- seria Leprieurii Mont., two species of Algse which I have found in all our estuaries from the Hudson to Tampa Bay. In company with them in the Ashley River, I found— Achnanthes brevipes, Ag. Meloseira nummuloides, Kg. Bacillaria paradoxa, Ehr. In fresh water ditches, at the same place, I found the following Alga*, viz : Vaucheria cespitosa, Ag. Spirogyra decimina, Kg. with the following Diatomacepe, viz: Bacillaria paradoxa, Ehr. Pinnularia viridis, Ehr. Diatoma Ehrenbergii, Kg. Surirella splendida, Ehr, Himantidium arcus, Ehr. MIDDLETON PLACE, ASHLEY RIVER. Dec. 16th, 1849.—In an artificial pond or reservoir at this locality, I found a great variety of interesting objects, among which were the following— Desmidie,e. A nkistrodesmus falcatus, Corda. Arthrodesmus convergens, Ehr. incus, Breb. Cosmarium margariferum, Menegli. Docidium verrucosum, B. Euastrum elegans, Breb. Pediastrum ellipticum, Hass. heptactis, Menegh. “ Napoleonis, Menegh. Scenedesmus quadricauda, Breb. Sphaerozosma excavatum, Ralfs. * “ serratum, B. Desmidieaj. Staurastrum gracile, Ralfs. “ muticum, Breb. Xanthidium cristatum, Breb. Infusoria. Arcella vulgaris, Ehr. “ dentata, Ehr. Lepadella ovalis, Ehr. Monostyla lunaris, Ehr. Peridiniura cinctum, Ehr. Rotifer vulgaris, Schrank. Squamella oblonga, Ehr. SAVANNAH, GA. December, 1849.—I had long entertained the belief that the earth of rice fields, from its frequent submergence, must contain a considerable quantity of infusorial remains; and on visiting Savannah, I gladly availed myself of the op¬ portunity to determine the truth of this supposition. The amount of infusorial remains which I detected far exceeded my expectations, but to my surprise I found that a large portion of the remains were of forms which only inhabit salt or brackish waters. Many of these forms are large enough to be seen by means of a pocket Coddington lens, and indeed it was thus that I first detected the infusorial character of the earths referred to. The large triangular Triceratium favus, Ehr., and the circular discs of Coscinodiscus subtilis, Ehr., may thus be seen in considerable numbers on the surface of every fresh fracture of the earth thrown from the rice-field ditches.
