sharks' teeth, dug from the Eocene and Miocene marly and 

 sandy strata of Charles, Prince George's, St. Mary's, and 

 Calvert connties. Especially may be mentioned the large 

 Ostrca compressirostra . from the region of Piscataway Creek, 

 the Perna and Pcctens from Forest's Landing on the Patiixent 

 river, and the bones of porpoises, with the shells of mollusks, 

 from the strata near Cove Point on the Chesapeake Bay shore. 

 Besides the foregoing*, there may be noticed a representative 

 series of the minerals and most of the sands and clays of Mary- 

 land which have been employed in the arts. Among the latter 

 were examples of the pure white sand and clay from Mr. Speer's 

 cliffs, on the Severn river, and the Nottingham diatomaceous 

 sand-rock from the bluff at the mouth of Lvons Creek, on the 

 Patuxent river, as also series of stuffed mammals and birds, 

 and a collection of bird's eggs. The Indian and aboriginal 

 relics from the State of Maryland also formed an important 

 feature of the collections of the Academy. An attempt was 

 made to bring together examples of the implements, utensils and 

 weapons of every tribe of Indians known to inhabit the State. 

 This endeavor was not very successful, partly because of the 

 rarity of such objects, and mainly from the difficulty of ascer- 

 taining to which group of aborigines the specimens should be 

 referred. Great numbers of arrow and spear heads, skin 

 dressers, and other stone implements, were given to the museum, 

 or collected by members for its use, and representatives of all 

 of these, besides steatite mortars and modern Indian textile 

 fabrics, were made accessible to the public in suitable glass 

 cases. Altogether, the collections even now existing form an 

 important foundation upon which to build a knowledge of the 

 past and present fauna of the State of Maryland.
