culpable negligence of those precautions which ought to 
be taken, have often caused more misfortunes and loss 
than the most contriving malice ; it is therefore of great

Description of a moveable Table , for the Use of Engra- 
vers; invented by the Abbe Joseph Longhi, of Monza * 
With an Engraving. 
THE art of engraving upon copper, which was at first 
invented to multiply and preserve copies of the best pic- 
tures of the most able painters, and portraits of the most 
famous men, and which has ever since its invention been 
much esteemed, is at present in such repute in every civi- 
lized nation, that its productions are become of great 
consequence, even when considered as an article of com- 
merce ; and, when this art is followed by young men who 
have both an inclination and a genius for it, what advan- 
tage may it not produce to their country, and to society 
in general ? But it often happens, as history testifies, 
that those artists who apply the most assiduously to it 
fall early victims to their assiduity, so that their first es- 
says become their last works. I myself remember, with 
great concern, several who have been taken from this 
world by a death more or less premature. Considering 
what could be the cause of this evil, as it was by no 
means difficult to discover, I found it to proceed from the 
* Repert. of Arts, vol. v. p. 354. From the Transactions of the Patriotic So- 
ciety of Milan. A gold medal was given to the Abbe Longhi for this invention.
