the experiments made by these gentlemen, the optical properties of 
nearly every chemical element were studied, over one thousand 
prisms of various combinations having been ground and subjected 
to spectrometrical measurements of their respective dispersion and 
refraction. The new objective is a one-eighth inch, composed of 
ten lenses, of which eight are composed of glass containing borates
