It was a translation, from English to Dutch, of a letter brought out in 1799 by Dr. J. T. van der Kemp of the London Missionary Society to their followers in the Cape, entitled "Brief van het Zendelings Genootschap te London aan de Godsdienst-lievende ingezetenen van de Caap de Goede Hoop".

It is possible that he made use of J.C. Ritter's press. Only one copy is known to exist and is in the South African Library.
