OBSERVATIONS AGAINST the USE of AMBER
SPECTACLES, (Second Edition) on the Preservation of SiAlit,
pages 55. and stis—" Amber is a soft substance, an,l it is impossible
to form It into a perfect lens, anti. a lens improperly constructed

" It: will probably be expected that I should say what I think of
AnWer gpcetaeles ; they have been recommended by several
o:Ailists, awl. my patronage has been solicited for them ; but surely
those gentlemen who have sanctioned them cannot have remem-

optician to his Alajesty, and Fellow of the Royal Society, informs
srie that he considers amber a very improper .material for Specta-
cles, on account of its colour, its not being homogeneous, ita
bility to scratches, and its being also impossible to form it into it per
