VEGETATION AND ANIMAL SAMPLES Coconut meat, Both plant and animal samples were received frozen with dry ice. The decause of its high oil content, was not ground but was broken into small chips and plant samples were spread in stainless pressed into the aluminum cans. steel pans and dried at approximately Coconut milk was mixed with for- 80°C for at least 24 h in a forced maldehyde and canned. draft oven until they reached constant samples were sifted weight. The dried plant materials were ground in a Wiley mill with a 2-mm screen, pressed into the aluminum mesh screen Litter through a 3 1/2- (5.613-mm openings) before being pressed into cans. The animal tissue samples were “tuna cans'' with a Carver press at sliced about 14,000 psi, and sealed. and bone were removed from muscle Sizes of cans were used, 210 em, ‘Two one containing the other 95 em” Samples thinly and freeze dried, tissue.
