Handbook of meat inspection . NERAL PATHOLOGY OF FOOD ANIMALS yellow-brown or grey-yellow. The liistological details, wliicli areeasily recognized witli tlie naked eye iu the normal organ, disap-pear, and the consistency becomes flabby and soft. Under themicroscope an appearance similar to that in cloudy swelling isobserved, except that the spherules are fatty instead of al-buminous. Differential diagnosis.—Fox the differentiation of cloudy swellingfrom fatty metamorphosis, we add acetic acid to a microscopicpreparation. The acetic acid dissolves the proteid globales, whilethe fat globules remain unchauged. Caustic potasli may also beused in makiDg the differentiation. The fat globules in warmingbecome saponified. Lastly, the fat globules in fatty degenerationare colored brown or black by osmic acid, while the proteid globalesin cloudy swelling do not give this reaction. It is, moreover, of great iraportance to distinguish betweenfatty degeneration and fatty Infiltration. The latter occurs prm- Fig. 45. Fig.
