To quickly assess the difficulty of the text, read a short excerpt:
Our knowledge is indeed so limited that what we are pleased to term theory i? really little better than speculation. HARGERIA, new genus. Ilesperornis gracilis differs so much from its larger relative that it should be placed in a distinct genus, for which the name Ilargeria is proposed in honor of Mr. Oscar Harger, who was one of Professor Marsh's assistants at the time of his investigations of the toothed birds, and, as noted in the preface to Odontornithes, rendered valuable aid in its prepa...ration. The most important character is the size of the quadrate and length of the ascending process, and in ]>irds this means much, as there is a remarkable constancy in the shape of this bone among related forms. As contrasted with Ifesperfytmii^ the genus Hargeria may be defined as follows: Quadrate with a large, upwardly directed lachrymal pro- cess; processes of nasals short; length of femur more than twice its gi*eatest width across the head.
