Many such specimens have beenfound, and the report of the Smithsonian Institution for 1875gives a short description of them. Those that the illustrationwas made from were found by me in Ashtabula county, Ohio,where I found several other good specimens, several of whichI have in my Perforated Humeri. From the collection of Doctor Snyder. Exhumed withfive other skeletons in Ashtabula county, Ohio. From a medical and surgical standpoint this peculiarity ofancient man should be of considerable interest, for in the skele-tons from which these specimens come one finds also a certainpeculiarity of the skull, and the flattened tibia is usually presentin a more or less marked degree. Aortic Compression—Sollmann and Pilcher 163 Effects of Aortic Compression on the Circulation By TORALD SOLLMANN, M. D., and J. D. PILCHER, M. D., Cleveland(From the Pharmacological Laboratory of Western Reserve University.) Occlusion of the aorta introduces an enormous increase ofthe resistance into the circulation and thereby raises the blood-pressure. The mechanism of this rise is of course very simpleand therefore peculiarly well adapted for studying the effectsof increased resistance and of rise of blood-pressure on the heartand on the nervous centers.
