(2) In books where there are images such as portraits, maps, sketches etc We have endeavoured to keep the quality of these images, so they represent accurately the original artefact. Although occasionally there may be certain imperfections with these old texts, we feel they deserve to be made available for future generations to enjoy.

DOWNLOAD EBOOK"Variation in the Muscles and Nerves of the Leg in Two Genera of Grouse (Tympanuchus and Pedioecetes)" by E. Bruce Holmes is a study about two closely related genres of grouse. The purposes of this study were: (1) to obtain information on individual variation in the anatomy of the muscles and nerves of the leg of Tympanuchus cupido pinnatus (Greater Prairie Chicken), T. c. attwateri (Attwater's Prairie Chicken), T. pallidicinctus (Lesser Prairie Chicken), and Pedioecetes phasianellus jamesi (Sharp-tailed Grouse); (2) to determine whether or not the two species of the genus Tympanuchus differ constantly in the myology of the leg; and (3) to determine what constant differences in the myology of the leg exist between the two closely related genera Tympanuchus and Pedioecetes.
