In respect to the form and use of the table, we may (1) retain complete alphabets, or we may (2) make use of a shortened form of the common alphabet, or we may (3) be content with half as many Stations.  If we fix upon the first method, then we must use a scheme of the sort I have just presented, or we may, equally well, use a circular or a square figure.  The circular figure is given below:

I will touch in few words on the way of using the figure.  The two-letter Stations, contained in the columns which make up the circle, embrace the alphabets in common use,  -that is , the Former General alphabet and, repeated against each letter of the General, the Particular.
