472 Letters from Benjamin Franklin 



To [Jean Baptiste] Le Roy. 1769. September 22. London. 



Has sent him one of the achromatic glasses complete, also three of 

 the glasses described in one of his printed letters. The astronomers 

 knew nothing before his return of the comet he [Le Roy] told him 

 about at Paris; they have since watched it very closely, but as the 

 French astronomers have observed it three weeks sooner, he supposes 

 they have been better able to determine its orbit. (Mutilated.) A.

To [Barbeu] Dubourg. 1769. September 22. London.
