The acid phosphatase in the egg also resembles that of the gut in being rather consistently more concentrated in all granule fractions than in the whole homogenate. The distribution of aryl-sulfatase ranges from 20 to 30% in Fraction I and from 20 to 40% in Fraction IV. The highest specific activity of RNAase, as well as the greatest nucleic acid: protein ratios, were found in the microsomal fraction, Fraction III. The highest per- centages of both RNAase activity and total nucleic acid are found in the soluble fraction; however, the recoveries of both these substances are quite high, when the combined amounts in the separated fractions are compared to those in the whole homogenates. It is interesting to note that considerable percentages of the recovered nucleic acid and RNAase were found to be present in the visible granule fraction (I), and in the intermediate granules (II), indicating the probable association of.
