Augusto de Almeida Teixeira was associated with the Campos Rodrigues Observatory, Lorenzo Marques (now Maputo), Mozambique, in 1913 when he became a member of the South African Association for the Advancement of Science, and was still there in 1918. The association held its annual congress in Maputo in 1913 and for this occasion he prepared two papers. One of these, written in Portuguese, was translated into English with the title 'Data for the study of the climate of Lourenco Marques' (33 pp.) and was based on meteorological data for the years 1910-1913. The other dealt with 'Determination of the latitude and longitude of the pillar of the transit instrument of the Campos Rodrigues Observatory'. The next year Teixeira, R.T.A. Innes* and W.M. Worssell* collaborated to determine the 'Difference of longitude between Johannesburg and Lourenco Marques' (Circular of the Union Observatory, Johannesburg, 1914, Vol. 15, p. 109).
