1 4-6 Mod-Suns.— Electro-Magnetic Experimoits. 



sculptured on the ceiling of the pronaos of that edifice was 

 made in the reign of Antoninus. Now this zodiac, as well 

 as that of the great temple, begins with the sign of the Virgin, 

 and the date of it had been also fixed at three thousand years 

 before tlie Christian aera. The temple itself, the erection of 

 which was assigned to that remote period, is not anterior to 

 the reio-n of Adrian. As for the planisphere of Denderah, we 

 know that M. ChampoUion reads on it in phonetic hieroglyphics 

 the word Autokrator, and assigns it to the reign of Nero. M. Le- 

 honne had also proved from Greek inscriptions, that the recUm- 

 gular zodiac of the pronaos must belong to the reign of Tiberius. 

 It may therefore be considered, as a fact resulting from posi- 

 tive researches, that not one of the four famous zodiacs dis- 

 covered in Egvpt is anterior to the dominion of the Romans 

 in that country. Ihe important facts connected with this 

 question are laid down by M. Lehonne in a work which will 

 appear in a few days, under the following title: ' Researches 

 into the History of Egypt during the domination of the Greeks 

 and Romans ; deriveci from Greek and Latin inscriptions, re- 

 lative to the Chronology, the state of the Arts, the civil and re- 

 ligious Usages of that Country.' 1 Vol. 8vo, pp. 600, with fac-

MOCK suxs. 

 At Dalmellington, Ayrshire, about mid-day on Saturday 

 25th January, four suns were observed in the firmament at 

 one time. An uncommon vivid halo, resembling a rahibow, 

 half-circled each of the mock suns, while the natural one was 

 entirely surrounded. The appearance of the whole was ex- 

 tremely beautiful, and exceeded in brilliancy and splendour 

 any thing of a similar nature which has occurred in the me- 

 mory of the oldest shepherds in that quarter. This phaenome- 

 non, though varied in appearance, was likewise visible at Ayr, 

 and in other places of the county. — Ayr Courier. 



NEW ELECTRO-MAGNETIC EXPERIMENTS. 



The following is a very curious and simple electro-magnetic 

 experiment made by Dr. Sebeck of Berlin. Take a bar of 

 antimony, about eight inches long, and half an inch thick ; 

 connect its extremi'aes by twisting a piece of brass wire round 

 them so as to form a loop, each end of the bar having several 

 coils of the wire. If one of the extremities be heated for a 

 short time with a spirit-lamp, electro-magnetic phsenomena 

 may be exhibited in every part of it. — Ann. Phil. iv. 313. 



ArEIGIITS AND MEASURES. 



A Bill for the Equalization of Weights and Measures has just 

 been brought into the House of Commons by Sir G. Clerk.
