Illustrations have been given of rare or impor-
tant diseases. Those of Elephantiasis Ai'abum
are selected from photographs from the Leper Hos-
pital at Rio Janeiro, presented to the Boston City
Hospital by Dr. B. E. Cotting. The large cuta-
neous horn is from a cast furnished me by Dr.
Durkee, and photographed on the wood previous-
ly to being engraved. The horn of the eyelid is



engraved from a life-sized photograph of a patient
of Dr. Henry L. Shaw. The plate ilhistratiug
eougenrtal canities is from a photograph whieh the
author ohtained of a patient of. Dr. David W.
Cheever, in the Surgieal Department at the Boston
Dispensary.
The Hthographs are from the establishment of
Mr. Crosby, of Boston; and the wood-eiigra\ings
were made by Mr. Richardson, of the firm of Rus-
sell & Richardson.
Many thanks ai-e due to those gentlemen who
have been interested in the pi'ogress of tliia work,
and who have contributed material for its pages;
and, with an earnest hope that it may meet with a
cordial welcome and suppoi-t from the student and
dermatologist, we hasten to fulfil our promise as
regards the other classes of skin-diseases.
