✦ Synopsis

A model has been developed for ordering diagnostic tests in jaundiced patients. The system proceeds in two steps: (i) diagnostic hypotheses are calculated for each patient from the results of physical examination and routine biological investigations; (ii) given these hypotheses, the most efficient test (out of 22) for reaching the final diagnosis is selected using four criteria: diagnostic value, risk, financial cost, and time in obtaining the result. This model was tested in 62 patients. In 43 of them (69%), the selected test was sufficient for reaching a diagnostic accuracy of 100%. In this group of patients, a mean of 3.7 (range 1-6) tests per patient was ordered by physicians. In the 19 remaining patients, the selected test was not sufficient for the final diagnosis, thus requiring a multiple choice process. It is suggested that such a system could help physicians to improve the care of patients by more efficient ordering of diagnostic tests.

The cultivation of hydrastis**This article is written in the first person, and, by request of the editor, gives facts concerning Hydrastis culture as observed in my own experimentations, corroborated by others known to me personally. No attempt has therefore been made to embody the experiences of persons who have heretofore printed articles on the subject, nor have my own previous publications, or my own photographs and detail notes'been used at all, excepting briefly. The cuts, excepting those showing the Hydrastis farm of Dr. Homsher, are from Drugs and Medicines of North America, 1884, or from others of my previous prints on the subject. The object being to present the problem so as to save to others experimental wanderings, I must yet urge the reader who proposes to enter the field of Hydrastis culture, to study carefully the Bulletins issued OR this subject by the Agricultural Department of the United States Government, especially the admirable pamphlet of Miss Alice Henkel and G. Fred Klugh, of the Bweau of Plant Industry.-L.
