Grateful acknowledgment must be made to Prof. E.A. FAY, of the
National Deaf Mute College, through whose special attention a large
number of the natural signs of deaf-mutes, remembered by them as
having been invented and used before instruction in conventional
signs, indeed before attending any school, was obtained. The gentlemen
who made the contributions in their own MS., and without prompting,
are as follows: Messrs. M. BALLARD, R.M. ZIEGLER, J. CROSS, PHILIP
J. HASENSTAB, and LARS LARSON. Their names respectively follow their
several descriptions. Mr. BALLARD is an instructor in the college, and
the other gentlemen were pupils during the session of 1880.

Similar thanks are due to Mr. J.L. NOYES, superintendent of the
Minnesota Institution for the education of the Deaf and Dumb,
Faribault, Minn., and to Messrs. GEORGE WING and D.H. CARROLL,
teachers in that institution, for annotations and suggestions
respecting deaf-mute signs. The notes made by the last named gentlemen
are followed by their respective names in reference.

Special thanks are also rendered to Prof. JAMES D. BUTLER, of Madison,
Wis., for contribution of Italian gesture-signs, noted by him in 1843,
and for many useful suggestions.

Other Italian signs are quoted from the Essay on Italian
gesticulations by his eminence Cardinal WISEMAN, in his _Essays
on Various Subjects, London_, 1855, Vol. III, pp. 533-555. Many
Neapolitan signs are extracted from the illustrated work of the canon
ANDREA DE JORIO, _La Mimica degli Antichi investigata nel gestire
Napoletano_, _Napoli_, 1832.

A small collection of Australian signs has been extracted from R.
BROUGH SMYTH's _The Aborigines of Victoria_, _London_, 1878.
