The Student's Spectroscope has a prism of extremely dense 

 glass, of very superior workmanship ; the circle is divided, and 

 reads with a vernier to single minutes ; the slit is fixed within 

 reflecting prism, by means of which two spectra can be shown as 

 the field of view at the same time. The instrument will divide 

 the D line in the Solar Spectrum, or the yellow Sodium lines 

 distinctly. With a slight alteration of the adjustments, the 

 instrument can be used for taking the refractive and dispersive 

 powers of solids or liquids. The Student's Spectroscope is 

 the best instrument for the Laboratory and for all general 

 work in Spectrum Analysis.
