The health status of four populations depending on traditional subsistence in Papua New Guinea was compared by the dipstick test urinalysis. Conspicuous inter-population difference in the distribution of urinary pH was attributed to the levels of protein intake and the balances of sodium and potassium intake. The percentage of positive findings on protein differed by population along with the percentages of urobilinogen and bilirubin; the higher percentage of protein positives (12-16%) found in less urbanized populations suggests a high risk of hepatic and/or renal disorders in traditional societies. The very low percentage, 0.3 percent, of positive findings on glucose among 1,132 urine samples tested indicated that diabetes mellitus was not yet the major problem. Simultaneously, however, the fact that glucose positives were found only in the most urbanized villages indicates increasing risk of diabetes even in the traditional populations during future urbanization.

RÉSUMÉ Série de mesures sur des éclats levallois d'un certain type, éclats pointus avec enlèvement central sur la face supérieure qui appartiennent à l'industrie de transition entre la paléolithique moyen et supérieur de la grotte de l'Amud (Israel). Le but de cette analyse est de mettre en évidence avec objectivité et de façon quantitative la dextérité manifestée lors du débitage. L'uniformité dans l'épaisseur de l'éclat et le parallélisme entre ses deux plans sont les facteurs considérés comme reflétant la précision du contrôle manuel.
