IMPROVEan.:Yrs IN LITHOC/RAPIIV.

A raname....en, whieh appeared in the Times of Wednesday, announces as new, the invention, by a young artist named Bt.:RNA/1u N- DOR r, of an improvement in lithography, consisting of' the use of dia- mond points it of the zwedles hitherto used in tracing (engraving) art stone. That such an invention does exist, is proved by the fact that,

eightegn inouths ago, we saw some beautiful specimUMS engraving an stone produced by the use of the diamond ; which were putt birth by in. II et, 1.31axnu5. in illustration of this new mode of lithograplay ; and these specimens were the first and only ones of the kind which have ap- peared from rut English press.

The writer of the paragraph alluded to, must be ignorant of the nature of lithography, and of the qualities of the stones employed, when he asserts that "the principal advantage derived from the use of the diamond is, that the hard veins which, in many instances, intersect the stories, are cut through with as much ease as the softer parts : " for it happens, that the "principal advantage" attendant on the use of the diamond, is an extreme delicacy, and firmness, and clearness of line, which can be produced by no other means, and which equals in beauty engraving on copper.
