The samples analysed came from the bottom of a small loch. No. 1 was of a yellow-gray eolour, even in texture, and readily broken down between the fingers.
No. 2 was distinctly red, and marked with dark spots. It broke down readily, and was more dense than No. 1.
No. 3 sample was red in colour, with dark brown and red particles throughout the mass.
