Accumulated lipids were extracted with ethylether from the adipose tissues of diseased turtles. Obtained lipids are very viscous, dark color, and contained extremely degenerated oil. Characteristic values of these oil are exceedingly abnormal as indicated in the Table 1 and 2. The characters of abnormal oil are remarkably different from the normal one such as specific gravity (0.94-0.96), acid value (2.4-9.2), peroxide oxygen (0.19-0.38g/kg), oxi-dised acid (5.3-9.0%) and mean molecular weight (770-830). But saponification and iodine values are not different from the normal values. Solubilities of the oil in several organic sol-vents are indicated in the table 3. These abnormal oils are contained only in the adipose tissue, but not found at all in the muscle and other tissues. Although the diseased body was under the starveling condition, accumulated oils were remained without consumption. The source of the degenerated oil in the living body is not evident now, but we can pre-sume that it must have been taken in the body as the diet, being accumulated chronically as a results of functional disorder on the liver and kidney by the poisonous effect of the oil. The old dried pupa of silk worm contains much degenerated oil as an example in the Table 4. Then we can presume that over-feeding of old pupa causes the disease in snapping turtles.
