calaqui nahui almo tlauli = four almudes of maize [seed?] can be planted; Lockhart says that five milli are being described and the number of almudes varies from one to four (Calimaya, 1738)
James Lockhart collection, notes in the file "Land and Economy." For this example he cites the Ayer Collection, Ms. 1477B (1). English translation proposed by Stephanie Wood.

Charles Gibson, Aztecs under Spanish Rule (p. 311), says that an "almud" is 1/12 of a fanega (0.73 acre).

motocha [sic (meaning motoca)] se almon yhuan tlaco = planted with 1.5 almudes; this was "se tlali" at the bottom of a hill, and it was sold by a former regidor to his compadre for 6 pesos
(Santiago Tianguistengo, Toluca Valley, 1756)
Stephanie Wood collection, notes from Nahuatl documents in the file "Bills of Sale," citing AGN (Mexico) Tierras 2547, exp. 9, f. 12r.–v.

"se nomill" = "one piece of land (milli) of mine;" this was sold by one "don" to another "don" for 11 pesos; it measured 25 quahuitl, said to be 20 and "tlaco" matlacquahuitl, and it held 2.5 almudes of maize seed. It would appear from this example that the matlacquahuitl or matlaquahuitl was slightly larger than the quahuitl. (San Miguel Almoloya, Toluca Valley, 1754)
Stephanie Wood collection, notes from Nahuatl documents in the file "Bills of Sale," citing AGN (Mexico) Tierras 2539, exp. 11, ff. 4r, 7r. (Spanish translation on 7r.)

ot yei almo = 3 almudes more
(Pizzigoni writes: "A strange detail is the replacement several times of syllable-final c by t, especially with oc in expressions meaning 'more, additional.'") (San Pablo Tepemaxalco, Toluca Valley, 1762)
