NORMAL KNEE-JERK.

Explanation of the Table.— In. the first column of the table is given the date of the experiments, and in the first line the hours of the day at which the examinations were made. Beneath the hours, on the same line with the dates, is arranged the average of all the experiments made in the seven examinations of the correspond- ing day. The table, therefore, enables one readily to compare the results of all the experiments made on each day and of all the ex- periments made at the same hour on different days. At the bottom of the table, under the hours, is given the average of all the experiments taken at the same hour on all the different days of the series. In addition to this, the table shows the average extent of the knee-jerk for each day ; the number of examinations and experiments which were made on each day ; and the mean of the barometer and thermometer for each day. Finally, at the bottom of the table, beneath these columns, is placed the average knee- jerk, as determined by all the experiments in the series, and the mean barometer and thermometer for the two weeks under con- sideration.
