✦ Synopsis

KO tissue has been studied microscoy?ically more than cross striated muscle yet there is inore confusion in our knowledge of the constitution of' the striated muscle fiber than any other histologic structure. Every textbook on histology states that the areas of Cohnheim wliich one observes i n transvcrsc sections, a r e cross sections of bundles of myofilrils separated by irrcgular clear lanes of sarcoplasm. The striated muscle fiber is evidently, according to current teaching, an cntirely different thing in cross section than it is in loiigitudinal scction. What happens to the alternate dark and light places of the cross striations when a transverse section is made through the striated muscle fiber? From textbook descriptiom they evidently disappear. unchecked iiiterprctation is then given which was origiiially prcsented 113- Kolliker (1867).

After completing this study and coming t o certain conclusions, independently, we wcrc snrprisecl to firid that the interpretation of the so-called areas of Colmheim, prcsciitcd in this paper, is the one proposccl originally by Cohnhciin (1865 a).
