But in the former experiment the veffel was cooled by the water very nearly 50 de- grees. In this experiment it was cooled nearly 15, fay, as 50 to 15, ::.91 toa fourth, which gives .27 for the heat received from the vefiel. The true temperature was 67.15, which was alfo the exact arithmetical mean. Hence the deviation from the arithmetical mean was .27. EXPERIMENT VY.
