    Notes: The horizontal viscous flow model with “infinite” areal extent can be used for almost any well flow problem whether two-dimensional or three-dimensional, steady or nonsteady, single aquifer or multiaquifer. This model can also be used in the field of soil mechanics for subsurface drainage problems. The design includes scale model analysis and the application of conformal mapping techniques in order to simulate an ideal aquifer. Construction, calibration, and test procedures for the model are described. The apparatus has proved to be both a valuable research tool and an excellent teaching aid.

    Description / Table of Contents: Zusammenfassung Ein neu entwickeltes „double-punch“-Verfahren für die Bestimmung der Zugfestigkeit von Gesteinen wird beschrieben. Die Vorbereitung der Versuchsobjekte und die Durchführung der Versuche werden erläutert. Außerdem werden die Zugfestigkeiten nach dem „double-punch“- und „split-cylinder“-Verfahren verglichen.
    Abstract: Résumé Dans cet article une nouvelle méthode de double poinçonnement permettant de déterminer la résistance à la traction des roches est présentée. La préparation des éprouvettes ainsi que la méthode d'essai sont décrites. Une comparaison est faite entre la résistance à la traction obtenue par double poinçonnement et par fendage d'un dylindre (compression diamétrale).
    Notes: Summary This paper presents an experimental study of the newly developed double-punch test method for determination of the tensile strength of rocks. The method for preparation of test specimens and test procedure is reported and discussed. Comparisons of tensile strength determined from double-punch and split-cylinder tests are also presented.
