On the estuary:—
Alej. Foster, "Regimen del Rio de la Plata y su corrección" (An. Soc. Cient. Argent., lii, 1901, pp. 209-234).
G. Rovereto, "Studi di geomorfologia argentina," ii, "Il rio della Plata" (Bol. Soc. Geol. Ital., xxx, 1911).
12. Population.
Besides municipal and provincial censuses, there have been three general censuses:
First census made in 1869, one folio volume published in 1872. I have only been able to consult Oficina del Censo. Informe sobre la operación y resultado del Primer censo argentino (Buenos Aires, 1870, octavo).
Second census of the Argentine Republic, May 10, 1895 (2 vols, quarto, Buenos Aires, 1898).
Tercer Censo Nacional levantado el 1º de junio de 1914 (10 vols, quarto, Buenos Aires, 1916-1917). Only the fifth volume, on agriculture, is not yet to hand.
A geographical interpretation of the distribution of the population was attempted by E. A. S. Delachaux, "La población de la Rep. Argent." (Rev. Univ. Buenos Aires, iii, 1905).
