Diriaion III, stemmed. — This divisioTi includes all vjirieties of stems, -whether 

 straijiht, pointed, or expanding, round or Hat, exccjit those with certain peculiari- 

 ties and included in Division IV; and whether the bases or edges are convex, 

 straight, or concave. 



Class A is lo/enge-shaped, not shouldered nor barbed. 



Class 15 is shouldered, but not barlted. 



Class C is shouldered and barbed. 



These cover the commoner forms of arrowpoints and si^earheads 

 throughout the workl. But there aie certain otliei forms which may 

 be few in number or restricted in locality and scarcely entitled to divi- 

 sions by themselves, yet are found in sufficient numbers and have such 

 definite characteristics that they cau not be ignored. These the author 

 has assigned to a general class under the head of "peculiar forms/' 



Division IV, pccuVmr forms. — This division includes all forms not belonging to the 

 other divisions, and provides for those having peculiarities, or the specimens of 

 which are restricted in number and locality. 



Class A, beveled edges. 



Class r>, serrated edges. 



Class C, bifurcated stems. 



Class D, long barbs, sc^uare at ends. Peculiar to England, Ireland, and (reorgia. 

 United States. 



Class E, triangular in section. Peculiar to the province of Chiriqui, Panama. 



Class F, broadest at cutting end, tranchant transversal. Peculiar to western 

 Europe. 



Class G, polished slate. Peculiar in North .\nierica tu the Eskimo country and 

 to New England and New York. 



Class H, asymmetric. 



Class I, curious forms. 



Class K, iierforators. 



DIVISK )N I— LEAF-SHAPED. 



The author essayed botanical and geometrical terms iu this descrip- 

 tion, but found them unsatisfactory. The imidements have such vari- 

 ety of form, each slightly different from the other, that specific terms 

 were scarcely ever applicable. They are lanceolate, as already men- 

 tioned ; leaf-shaped, but as leaves have many different forms, so have 

 these implements, and "leaf-shaped'' is rather generic than specific. 

 He essayed the geometrical terms of ovate, oblong, truncated, elliptical, 

 lenticular, but found he could only use them in descrii)tions of indi- 

 vidual specimens. 



Dr. Eau, in his unpublished paper, speaking of leaf-shaped imple- 

 ments, said: 



These are numerous and of great variety in form and size, insomuch that a minute 

 classilication would bo difficult. However, thej' can be divided in a general way 

 into three classes, in accordance with their being rounded at one end and pointed at 

 the other, or pointed at both ends, or rounded at both ends. They vary in length 

 from less than an inch to more than 13 inches, and there is in the National Museum 

 a cast of a sword-like flint blade measuring more than 21 inches iu length, which 

 by its form pertains to the class here treated. The oiiginal, from a mound in Ten- 

 nessee, is in the possession of Dr. Joseph Jones, of New Orleans.
