THE MICROSCOPE. 79 



WE have received a condensed list of microscopes and ac- 

 cessories for sale by the old house of J. Grunow. Established 

 in 1852 it has continued to prosper by business tact and by a deter- 

 mination to keep well informed of the wants of the working micros- 

 copist, and then supply the want with promptness and satisfaction. 

 We have in our possession one of their earliest, and at that time one 

 of their largest microscopes. We use the stand and accessories to- 

 day. Goniometer, parabolic condenser, polarizing apparatus, etc., 

 all complete. Send for one of their catalogues. 



Ancient Dentistry. — Sir Gardiner Wilkinson affirms that 

 teeth stopped with gold have been found in Egyptian mummies, and 

 other learned gentlemen hold vigorously tnat the thing is an impos- 

 sibility. Dr. John Gaigor, in the interesting discussion going on in 

 the British Medical Journal, says that in the Etruscan museum of 

 Corneto, the ancient Tarquina of Etrurio, and a few hours distance 

 from Rome, he has seen teeth in a skull bound together by threads 

 of gold cleverly twisted in and out among them; and that he has 

 seen the same thing in museums in the Vatican and elsewhere. 

 From these facts he presumes that it is quite probable the ancient 

 Egyptians had more or less skillful dentists. His deduction is sup- 

 ported by a gentleman who is positive that he once saw in the 

 Meyer museum in Liverpool, the jaw bone of a mummified Egyp- 

 tian in which a number of teeth were secured by a golden wire. It 

 is also claimed that the Hindoos, 600 years ago, knew something 

 about the art of binding together teeth that were disposed to 

 abandon each other's company. Mr. Briggs, in his " Rise and 

 Fall of the Mohammedan Power in India," describes a battle in 

 which Kootubood-Din, the famous general of Mohammed Ghory, 

 who built the Kootub, a tower which rises near Delhi to a height 

 that makes it one of the most beautiful wonders of the world, slew 

 with an arrow a powerful rajah whose corpse was afterwards identi- 

 fied, according to the writings of Ferishta, by his artificial teeth, 

 which were bound together by wires of gold. — Ex.
