^ijQ Singida7- Clock. — Lectures. 



M. Griebel, a watch-maker of Paris, has invented a clock 

 without weights, ot" a globular form, the dial-plate of which 

 is traasparcirt, and, by means of a r'jflecting lamp on Ar- 

 gand's construction, shows the figure to a great distance. 

 By a particularity of formation, neither the wheels, the 

 hands, nor the pendulum, cast any shadow. The light may 

 be made stronger or weaker, and adapted to the sick-cham- 

 ber, or to clocks in the most public situations ; where it 

 answers the purpose of a time-piece and a lamp at the same 

 time.
