Lines Measured in the Second Photograph. 



For the eye observations, the new 3-foot mirror, which has recently 

 been presented to the Astrophysical Laboratory by Mr. Common, was 

 employed, but unfortunately the clock is not yet mounted, so that 

 the observations were difficult. 



C was the brightest line observed. In the green there were 

 several lines, the brightest of which was in all probability F, the 

 position being estimated by comparison with the flame of a wax 

 taper. Another line was coincident, with the dispersion employed, 

 with the radiation at X 500 from burning magnesium wire. A fainter 

 line between the two last named was probably near X 495, thus com- 

 pleting the trio of lines which is characteristic of the spectra of 

 nebulae. There was also a fairly bright line or band coincident with 

 the edge of the carbon fluting near X517 given by the flame of the
