The table presents at a glance the beginning and end of 280 days for every day in the year. Find the date of menstruation in the upper line of the horizontal column, and the figure below, with the corresponding month, will indicate 280 days. =To Avoid Miscarriage.=--The pregnant woman must be very careful as the usual time for menstruation approaches. It is then that any undue effort, unusual lifting, excessive grief, or shock to the system, may bring on a miscarriage. This is especially true if such a misfortune has previously occurred.
