On observing a cross section through fresh or well-preserved muscular fibres, the sarcoplasm is seen as transparent lines sub- dividing the muscular contents, which appear dim like ground glass, into small more or less polyhedral areas, the areas of Cohnheim. These areas are the cross-sections of the muscular columns, and are therefore made up of a number of granules, the optical cross-sections of the constituent fibrillae. The mus- cular columns appear aggre- gated by larger accumulations of sarcoplasm into larger or smaller groups; and between the groups the sarcoplasm is again greater than between the fibrillae of each column, and in this respect there exists the greatest variety between the different animals. In the per- fectly fresh condition tlie amount of sarcoplasm between the fibrilhe of a column is in some cases insignificant, and almost appears absent from place to place. Tlie sarco[)lasm shows also other differences of A'—. \ jL Fig. 64.—Mu>;cul;ir Fibre, stained with hitmatoxy- lin, of Staphylinuscaesa- reus. {liollett.)
