Paper, 'The development of Peripatus capensis [Peripatopsis capensis]' by Adam Sedgwick

Description

Sedgwick writes: 'The development of Peripatus capensis was first studied by Moseley, who stopped for a short time at the Cape in November and December some years ago. His observations related only to a few stages comparatively late in development. Balfour, in 1882, found some younger embryos in specimens collected by Mr Lloyd Morgan in July and August. He had only time to make a very few observations, of which he left a short record in the form of four rough drawings and a short note, and a letter to Professor Kleinenberg, before starting on his last expedition to Switzerland. His observations were so interesting that they were made the subject of a short communication to the Royal Society in the autumn of 1882, and they were slightly extended by the editors of his last work on the anatomy of Peripatus capensis, and published with that monograph in the “Quarterly Journal of Microscopical Science” in the spring of 1883. The subject seemed so important that the Government Grant Committee of the Royal Society granted, in the spring of 1883, the sum of £100 to enable me to go to the Cape for the purpose of obtaining well-preserved embryos, and of studying the development on fresh specimens.'
