619 The Patent Pantoscopic Spectacles are so constructed as to enable the wearer 

 to read or write with comfort. When the Spectacles are on the face, the position 

 of the lenses is such that the light passes through them at right angles to their 



urfaces, and the upper part of the lenses being slightly straightened, enables the 

 earer to converse with anyone, or see distant objects, without looking through 

 he lenses or drawing the Spectacles down upon the face, Figs. 619 and 619*. 

 N". & Z. strongly recommend this form of Spectacles.
