SANITARIUM 



FOR 



NERVOUS DISEASES, 



Washington, D. C. ""''^?^.'*"/„,.' • -.^ 



13*.. William .\. H.a.mmond annoiunces to the medical profession that in Noveml.cr iuxl he will return from 

 New York .to Washington, D. C-, where he is establishing, in a building especially being erected for the purpose, a Sani- 

 tariiim for tfee treatment of mild and curable cases of mental darangement, diseases of the nervous system generally, and 

 cases of the isiorphia and chloral habits. His experiexice during many years has convinced him that most affections 

 embraced wit'hin the above-named classes can be treated much more successfully in an institution of this kind, under the 

 constant supen^•ision of the physician and with the aid of means not otherwise at command, than when the patients^arg 

 st.eB by their iiaedical advisers at intervals of several hours or days. 



Tlie Sanitarium, which is now being constructed under the superintendence of A. B. Mullett, Esq., late architect 

 of the United States Treasury department, is situated on Columbia Heights, at the corner of Fourteenth Street and Sher- 

 idan .Avenue. The position is the highest in the immediate vicinity of Washington, the soil is dry, and all the surround- 

 ings are free from noxious influences. It is readily reached by the Fourteenth Street Railway, the cars of which run to 

 the doors. The building will be very large, and as perfect in structure and arrangements as may be possible from a 

 knowledge of sanitary science and of the requirements of such an institution. It will accommodate about thirty patients. 

 So far as the rooms, table, etc., are concerned, they will be fully equal to such as e.xist in the best hotels of our large 

 cities. Electricity in all its forms, baths, douches, massage, inhalations, nursing, etc., will be provided as may be required 

 by patients, in addition to such other medical treatment as may be deemed advisable, and without e.xtra cost. 



-A. large Solarium for sun-baths and e.xercise in cold or inclement weather and to be heated with steam in winter, 

 is being constructed on the top of the main building. 



The Sanitarium will be open for the reception of patients on or about November ist, iSSS. 



For further information Dr. Hammond can be addressed at his present residence, No. 43 West 54th Street. New 

 York, till November ist; after that date, at Washington, D. C.
