Jarric's work gives a comprehensive picture of the missionary enterprises of the Jesuits up to 1610, chiefly within the sphere of Portuguese interests. It contains much valuable data on colonial history, geography, and ethnography, taken from Spanish and Portuguese reports, and from the works of Father Luis de Guzman (Hist. de las Missiones que han hecho los religiosos de la Compañia de Jesús), and of Father Ferdinand Guerreiro (Relação Annal das cousas que fizeram os Padres da companhia de Jesus na India e Japão, Brazil, Angola, Cabo Verde, Guiné).
