I am only aware of cases reported from the Gold and Ivory Coasts of West Africa and the West Indies. I never met with it in Mamprusia, nor have I met any trader coming from Moshi with it, nor have I met with it in Fra Fra, and I can find no one who has seen it in the eastern parts of the colony. But in the following districts it has been noted: Ahanta, Appolonia, Fantee, Accra, Aquapim, Akim, Assin, Sefwhi, Ashanti, Attabubu, Kwahu, Kintampo, Berekum, Gaman, the Neutral Zone, and Wassaw. It is perhaps most common in the Sefwhi, Wassaw, and Appolonia districts which adjoin the French Ivory Coast, where cases are also known. I look upon henpuye as a localized osteoplastic periostitis in the region of the nasal process of the superior maxilla, generally symmetrical, due to yaws, and found among the natives of West Africa and the negroes of the West Indies. THE MADDOX ROD OR THE PHOROMETER; WHICH? In the last issue of the Journal there appeared an abstract with the above title, and believing the subject to be of much interest at the present time, our readers have been invited to send us their opinions on the matter, as based on the experience obtained in practice. The communications below have been received and are presented in the order of their reception. We shall be glad to hear from any physicians who are interested [ED.]. DEAR DR. DEADY: In reply to your favor requesting my opinion regarding the respective merits of the Maddox rod and the diplopia test, I wish to say that my experience leads me to rely more and more upon the obscuration test, and while I have not followed out the comparison to any great extent, such as is shown by your tables, results obtained by relying upon the rod test in the detection of heterophoria, as well as in determining when the weak muscles have been sufficiently developed, have been such as to warrant my continuance of its use. E. D. BROOKS. I have with interest watched the discussions of late, as to the relative value of the Maddox or Stevens tests for heterophoria, as I have for years used them both. My muscle tests have been made for the last five years at least, with a Risley phorometer, which combines both tests upon one arm and has proven for me a most satisfactory instrument.
