386 Mr. J. N. Lockyer. [Feb. 28, 



fluting at 615 is present, and is a little stronger than in Aldebaran. This 

 and the relative thickness of F lead to the conclusion that the star 

 falls between a Ceti and Aldebaran. Carbon 517 has disappeared. 



a Tauri. F, E, and 499 are all about the same intensity, but none 

 of them are so strong as ~b or D. The trio is present, E being a little 

 thicker than the second and third members. All three are seen to be 

 double when a high power eyepiece is employed. 579 is nearly as 

 thick as E and is stronger than 568. Groups of lines near 546 and 

 558 are fairly strong. 552 is also well seen. The Fe (1) fluting in 

 the red (615) appears rather weak, and a pretty strong line runs 

 through it near the most refrangible edge. There is also a line 

 between b and 499, another between E and 5327, and many others. 

 The Mn (2) (586) fluting is possibly visible at times. 



X Ophiuchi. F is slightly stronger than in a. Tauri, but is a little 

 thinner than E. Not so thick as in <x Cygni or a, Serpentis. D is the 

 strongest line in the spectrum and b comes next. 579 and 568 are 

 both about the same intensity as E ; so is 540, whilst the remaining 

 member of the trio is rather weaker. The lines near 546 and 558 are 

 fairly strong, as is also 499. The iron band in the red is absent. 



/3 Ophiuchi. F and E are about equally thick in the spectrum of 

 this star. F is thicker than in Arcturus, but is not so thick as in 

 a. Cygni. The trio is complete, all the three lines being very well 

 seen, b is the strongest line in the spectrum and D is the next. 568 

 is present, but weaker than 579. The lines near 546 and 558 are 

 also certainly present. The line at 499 is about as thick as E. 552 is 

 present. 



e Pegasi. F is about as strong as in a. Aquarii ; D and b are about 

 equal and as strong as F. 579 is stronger than 568 but is not quite 

 so strong as D. E and 540 are not nearly as strong as 579 ; the other 

 member of the trio (5327) is very distinct. 499 and the lines near 546 

 and 568 are all fairly strong. 552 is also present. 



at Aquarii. F and b seem about equal in intensity in the spectrum 

 of this star. D is not quite so strong as b, but is a little stronger 

 than E ; the other two lines of the trio are rather faint. 579 is about 

 as strong, or perhaps stronger, than E. 568 is much weaker than 

 579. 499 is a fairly strong line. The lines near 546 and 558 are well 

 visible. 



7 Aquilce. F is not nearly so strong as in * AquilaB, and is a little 

 thinner than in a. Cygni. b and D are well defined, and about equal 

 in intensity, whilst E is a little weaker; the remaining members of 

 the trio are fainter than E. 579 and 568 are present, the former being 

 about as strong as E, but the latter is barely visible. 499 and the 

 faint lines near 546 and 558 are present ; also an important line less 

 refrangible than D, which was found by comparison with the electric 

 spark to be near 598. Another fainter line was seen near 612.
