Description
Drawing of Robert Hooke's instrument for collecting the wind or for making the slower motions of the air more sensible. Hooke's instrument is a modification of one contrived by William Croone, and connects two hollow tin cones at their common point, or vertex, shown at a. Hooke divides the limbs into 32 equal parts, cut with many triangular valves or partitions, leaving a cylindrical hole in the centre of the instrument fit to contain a small vane or weather-cock. The valves or partitions are attached between the two cones so that air passes through the small holes into the small central square at a. In addition to collecting wind, Hooke writes that this instrument could be used for balancing a ball on top of a steeple-turret, and for amplifying sound when it is placed on the ear.
