The sixth column contains tliesymbols of the chemical substances 

 to which, according to the maps above referred to, the lines owe 

 tlieir origin. 



Tliere are no disagreements between tlie two authorities ; in a 

 majority of cases, liowever. Angstrom alone indicates the element, 

 and there are several instances where the lines of more than one 

 substance coincide with each other and with a line of the solar 

 spectrum so closely as to make it impossible to decide between 

 them. 



In the seventh and last column the letters J., L,, and R. de- 

 note that to my knowledge the line indicated has been observ€fl 

 and its place pul^lished by Janssen, Lockyer, or Rayet. It is 

 altogether probable that a large portion of the other lines con- 

 tained in the catalogue have before this been seen and located by 

 one or the other of these keen and active observers, but if so I 

 have as yet seen no account of such determinations. 



I would call especial attention to the lines numbered i and 82 

 in the catalogue ; they are very persistently present, though fliint, 

 and can be distinctly seen in the spectroscope to belong to the 

 chromosphere as such, not being due, like most of tlie other lines, 

 to the exceptional elevation of matter to heights where it does 

 not properly belong. It would seem very probable that both 

 these lines are due to the same substance which causes the D^ 

 line. 



I do not know that the presence of titanium vapour in the 

 prominences and chromosphere has before been ascertained. It 

 comes out very clearly from the catalogue, as no less than 20 of 

 the whole 103 lines are due to this metal.

SCIENTIFIC SERIALS 



The American N'atnralist for October 1871 commences with 

 a paper by Dr. Jeffreys Wyman entitled, " Kxperiments with 

 -Vibrating Cilia," the chief points in which are some determina- 

 tions of the rate of movement of the vibrating cilia on the gills 

 of Mollusca, both in air and in water, and the description and 

 drawing of an instrument by means of which this rapidity can 

 be measured and exhibited so as to be seen over a large lecture- 

 room. Prof. James Orton furnishes some contributions to the 

 Natural History of the Valley of Quito (continued in the next 

 number) ; and Dr. J. S. Billings contributes a paper on Ilyslciiniii, 

 a genus of Ascomycetous Fungi, and some of its allies, illus- 

 trated by a plate. Mr. T. Martin Trippe has a very interesting 

 paper on some differences between Eastern and Western Birds, 

 in which he traces the difference in habits, note, time of breeding, 

 &c. , in the same species of bird in the eastern and newly-settled 

 western portions of the American continent, and the manner in 

 which the indigenous avifauna of the Western States is becoming 

 gradually superseded by eastern forms, along with the advance 

 of man. 



The first paper in the number for November is by Grace Anna 

 Le•,^'is on Symmetrical Figures in Birds' Feathers, in illustration 

 of the beauties furnished for the microscope by the feathers of 

 birds. Dr. Elliott Coues gives a description and drawing of a 

 litlle-known species of oriole, the only one which is a native of 

 the Western States, and is know-n as Bullock's Oriole, Xaiilhorihus 

 BtiVoikii, Swainson. Prof. George H. Perkins contributes some 

 "Notes on the Geodes of Illinois;" and the remainder of the 

 number is occupied by reviews, and the usual interesting items 

 of Natural History Miscellany. 



The number for December opens with an extremely interesting 

 paper by the Editors on " The Mammoth Cave and its Inhabi- 

 tants," an account of a visit paid to this extraordinary cavern in a 

 hill of the sub-carboniferous limestone formation in Edmondson 

 County, Kentucky, after the Indianapolis meeting of the Ameri- 

 can Association for the Advancement of Science. After a 

 general description of the cave and history of its inhabitants, it 

 contains a description, with drawiirgs, of all the species of Crus- 

 tacea and insects which are found in it. The Rev. Samuel 

 Lockwood writes an account of "ASinging//i-,f/i-r<;«/;'ior Vesper- 

 mouse," the species known as the jumping-mouse, wood-mouse, 

 and white-footed mouse, with the notes of its song. This num- 

 ber concludes Vol. v. of this admirably-conducted magazine, 

 which we commend to the notice of all interested in the study 

 of natural history.
