THE MARYLAND CYCADS. 455 



broken must have been much longer. It was small and somewhat 

 elliptical in cross section. The fracture at the upper end is nearly even, 

 that at the lower end is irregular, the lowest point coinciding with the 

 end of the ellipse, thence sloping upward in both directions, so that 

 the shortest side is 6 cm. less than the longest. The specimen includes 

 nearly all of the medulla. The color is a pinkish red throughout. The 

 specific gravity is much less than that of most trunks, chiefly on account 

 of the number of empty cavities, large and small. It weighs 3.42 kg. 

 The total height is about 18 cm. The longer diameter is about 16 cm., 

 but this falls a little on one side of the center. It was probably nearly 

 17 cm. The radial thickness is 11 cm., which includes about the whole 

 of the medulla. (Locality: PI. LXXX, near No. 53.) 



PL C represents the perfect trunk No. 2 of the museum of the 

 Maryland Academy of Sciences, otherwise known as the Lee trunk, 

 being from a platinum print made by Mr. Smillie. It is a view of the 

 side that shows the largest amount of surface and affords a clear idea 

 of the specimen. It is a small, simple trunk, strictly conical in shape 

 and nearly perfect both in the absence of fracture and in the state of 

 preservation. It has suffered no compression or erosion and is nearly 

 circular in cross section at all points. The maximum height is 28 cm., 

 but the base is oblique (not due to fracture) and the shortest side meas- 

 ures only 23 cm. The diameter at the base varies from 17 cm. to 20 

 cm., and diminishes regularly to the apex, where it is 9 cm. at the point 

 where it begins to narrow abruptly. The maximum girth is 58 cm. 

 It is oblique at the summit and has suffered slightly from decay on 

 one side. There is no terminal bud or true crow's nest, but an irreg- 

 ular cavity 2 cm. deep at one side of the center is partly occupied by 

 the remnant of scale-like matter that may have belonged to the bud. 

 The trunk is also rapidly contracted at the immediate base and seems 

 to have grown on a steep slope, so that one side was naturally much 

 lower than the other. The trunk is of a grayish-brown color through- 

 out, silicified, but having a low specific gravity in consequence of its 

 porosity. The weight is 7.66 kg. (Locality: PI. LXXX, near No. 54.)
