The float is connected to a pulley system that turns the peahen, so that as the float rises, the peahen will rotate, see Fig. 3. There is a weight at the other end of the rope, which is lighter than the float, and this keeps the rope taut at all times. The peahen is initially facing to the right, and the pulley system will turn the peahen 180 o to its left in half-an-hour.An Act for enabling James Cox, Jeweller, to dispose of his Museum, commonly called Cox's Museum, by Way of Chance, in such Manner as may be most for the Benefit of himself and his Creditors.

There are 15 glass roundels to correspond with the maximum number of daylight/night hours. For example, on the summer solstice there are 14.5 hours of sunlight, and 9.5 hours of the night, and vice versa during the winter solstice. Keep collections to yourself or inspire other shoppers! Keep in mind that anyone can view public collections—they may also appear in recommendations and other places. The above will occur at every half hour for all the hours of the day, and will continue throughout the night, but with the addition of a lit candle behind the crescent disc. Thus, as the hours of the night go by, the crescent disc will rotate to reveal light through the roundels. How does it Work?Al-Jazari’s book contains 50 mechanical devices, along with minute instructions on how to construct them, providing an invaluable contribution to the history of engineering. The devices are grouped into six categories: A speech by Professor Salim Al-Hassani on the occasion of the “Generation’s 2023 Innovation Fair”, Pakistan George Sarton, “Introduction to the History of Science”, 1927, vol. 2, p. 510.

Though he hoped for royal patronage, and displayed, as was common, royal portraits in the museum, [4] Cox never achieved his goal. In 1773 a special Act of Parliament ( 13 Geo. 3. c. 41) authorised Cox to break up his collection and sell pieces by lottery.
