All the specimens that were kept dry, whether carbonised or not, were apparently in good condition; but those which had been placed in manure or damp earth, were more or less in a state of decomposition, the softer parts of the concentric layers being slightly wasted away with rot on the surface. The difference in strength between the carbonised and non-carbonised pieces was not very great, but the tables show that of the pieces kept dry, the loss of strength was greatest by about 8 per cent, in the carbonised specimens; and of those kept in manure, the loss was about per cent, in excess on the non-carbonised pieces. When the experiment for testing the strength was completed,
