Remouchamps Cave is located in Frasnian limestones. These limestones are pure, sometimes dolomitic, and in thick beds. The cave displays two levels. The lower one (underground river) is at the level of the main outside river. The upper one, 10 m. higher, is dry. It is also an ancient river bed, but it includes large halls. These halls display huge collapses. [less ▲]

Sulpiride, a new psychotropic drug with neuroleptic activity, was administered to rats in a sidman avoidance schedule. Doses ranging from 1 to 80mg/kg resulted on the animal recieving fever shocks. This effect was not correlated with an increase of responding and seemed unrelated to the suppressing action abruptly observed at high doses (i.e. 150 to 200 mg/kg). These results differ from those classicaly obtained with other neuroleptics. [less ▲]

The interest of a spectroscopic investigation of the upper atmosphere of Venus in the ultraviolet is briefly shown. The conditions for the observations to be made are defined and the main properties of the necessary instrument are deduced and described. The proposed package is a quadruple miniature spectrometer covering the entire spectral range extending from 1200 A to 8000 A with a resolving power of 500. [less ▲]

Pigeons' key peck were brought under the control of the duration of a visual stimulus in one-key and two-key procedures. In the one-key procedure, pecks were reinforeced after presentations of a long-duration stimulus but not after presentations of a short-duration stimulus. In the two-key procedure, left-key pecks were reinforced after the long-duration stimulus and right-key pecks after the short-duration stimulus. In both procedures, the long-duration stimulus was 10 sec, and the short-duration stimulus was increased from 1 to 8 sec in1-sec steps. Discriminative control developed with both procedures, but with greater acuracy in the two-key procedures, in which a difference threshold was obtained at short-duration values between 7 and 8 sec, or about 2.5 sec shorter than the long-duration stimulus.
