Blyth, Edward (1810-73): distinguished for his knowledge of Indian birds
and mammals. He was for twenty years Curator of the Museum of the
Asiatic Society of Bengal, a collection which was practically created by
his exertions. Gould spoke of him as "the founder of the study" of
Zoology in India. His published writings are voluminous, and include,
in addition to those bearing his name, numerous articles in the "Field,
Land and Water," etc., under the signature "Zoophilus" or "Z." He also
communicated his knowledge to others with unsparing generosity, yet--
doubtless the chief part of his "extraordinary fund of information" died
with him. Darwin had much correspondence with him, and always spoke of
him with admiration for his powers of observation and for his judgment.
The letters to Blyth have unfortunately not come into our hands. The
indebtedness of Darwin to Blyth may be roughly gauged by the fact that
the references under his name in the index to "Animals and Plants"
occupy nearly a column. For further information about Blyth see Grote's
introduction to the "Catalogue of Mammals and Birds of Burma, by the
late E. Blyth" in the "Journal of the Asiatic Society of Bengal," Part
II., Extra number, August 1875; also an obituary notice published at the
time of his death in the "Field." Mr. Grote's Memoir contains a list of
Blyth's writings which occupies nearly seven pages of the "Journal." We
are indebted to Professor Newton for calling our attention to the
sources of this note.

Blytt, Axel Gudbrand (1843-98): the son of the well-known systematist M.N.
Blytt. He was attached to the Christiania Herbarium in 1865, and in 1880
became Professor of Botany in the University. His best-known work is the
essay referred to above, but he was also known for purely systematic work
in Botany as well as for meteorological and geological contributions to
science. The above facts are taken from C. Holtermann's obituary notice in
the "Berichte der Deutschen Bot. Gesell." Volume XVII., 1899.
