Note 21 — Chapter II · RIO DE JANEIRO AND ITS ENVIRONS.—JUIZ DE FORA.

Leuzinger’s admirable photographs of the scenery about the Corcovado, as well as from Petropolis, the Organ Mountains, and the neighborhood of Rio generally, may now be had in the print-shops of Boston and New York. I am the more desirous to make this fact known as I am indebted to Mr. Leuzinger for very generous assistance in the illustration of scientific objects.—L. A.
