270 Mexico: Guerra y Marina 
FRACCION PRIMERA. OPERACIONES MILITARES. 
(First Division. Military Operations.) 
This division covers the period from 1821 to 1867, and contains perhaps 
1000 legajos, of from 500 to 1000 folios each. The legajos are numbered in 
separate series for each year or group of years. Down to 1856 each legajo 
bears a membrete, or ticket, showing the division (fraccién), legajo number, 
dates embraced, and principal subjects treated by the documents within. For 
the period after 1856 the documents are arranged in legajos on an alphabetical 
basis. The membretes of these latter lezajos do not show the contents, but 
this is indicated in a general inventory (indice) kept in book form.
