Part II. — Reduction of the Instrumental, to a Wave-Number, Scale. 



The shape in which the Winchester Spectrum work was brought to Edin- 

 burgh on July 30th, consisted in three packets of seven lengths of paper each ; 

 every such length containing 19 to 20 parallel, but consecutive revolution strips, 

 and each strip, 14 inches long, holding on an average the recording marks for 

 about 50 Fraunhofer lines. So that each of the three spectra might be formed 

 into a continued length of nearly 160 feet of paper, holding something between 

 and 7,000 symbolic notings in its course, to indicate various characteristics 

 besides the very important one of angular place, by micrometric screw 

 measure, of as many solar, spectral; " fixed " lines.
