Note 126 — LETTERS ON ART.

Christian Gottfried Ehrenberg, the naturalist and author of many works, of which those on infusoria may be especially noted here. He was born in 1795, and in 1842 was elected Principal Secretary to the Berlin Academy of Science, which post he held till his death in 1876. The late Sir Walter Calverley Trevelyan, Bart., will also be remembered in connection with the study of natural science, as well as for his efforts in philanthropy. He died in March, 1879. I have been unable to find any further information as to the prize mentioned by Mr. Ruskin, or as to the essay which obtained it.
