These cases cannot be entered in the table, in consequence of my being unable to determine the precise day of the attack on which the relapse occurred. The duration of this relapse, or the date of its crisis in relation to that of its accession, is shown in 112 cases; the average date of the crisis on the wdiole of these cases is the third day, reckoned from the day of relapse. In 105 of these 112 cases, the day of the attack on whicli the second crisis occurred can be easily t- reckoned from the preceding table. I shall not therefore state this calculation, but proceed at once to the second head. The Date of the Second Crisis in relation to It must be distinctly understood that the term date througliout this section is applied to the day of the second crisis reckoned from the day of the relapse. Of the 112 cases in which the date of this crisis is ascertained, tliere are 67 males, 45 females. 1. The 3 cases wdiich presented the second crisis on the first day of the relapse are all males. Tliis gives, as the frequency of this second crisis on the first day, 4*3 per cent, for males. 2. Of the 18 cases whicli presented the second crisis on the second day, 13 arc males, 5 females. This gives as the frequency on this day, 19*4 per cent, for males, 11 for females. 3. Of tlie 25 cases which presented this crisis on the third day, 19 arc males, 6 females. This gives as the f!*e<]nency of this ci-isis on this day, 28*3 per cent, for males, 13*2 fer feniab's. 4. Of the 31 cases wliich presented tliis crisis oa tin* {'oiirth
