The report in this issue by Dr. Hall of a case of ankylostomiasis in a sailor, dying from this disease in Baltimore, shows the importance of careful examination of the feces in obscure cases of anemia associated with intestinal disturbances. Ankylostomiasis, or uncinariosis, is a comparatively unknown disease in the United States. In some of the new possessions, however, it is probably quite as frequent as in other countries, such as Egypt. According to Lieutenant B. K. Ashford1 ankylostomiasis is the most general and most harmful disease—a veritable curse—in Porto Rico. Allyn and Beard2, reporting a case in an Italian in Philadelphia, review some of the cases observed in this country, and they express the belief that it is more frequent than the few scattered reports seem to indicate3. The diagnosis is established by finding the ankylostoma eggs in the feces. The eggs are described by Manson4 as beautifully clear and transparent, 55 to 65 by 32 to 43 mikrons in size, oval, with delicate transparent shells, through which two or four light gray yolk segments can be seen distinctly. The ova are to be sought for soon after the feces are passed.
