BIBLIOGRAPHY 



BEFORE his last illness Tail had begun to prepare material for the third volume of his 

 Scientific Papers. A special feature was to have been a complete bibliography of his contri- 

 butions to scientific journals, with short explanatory remarks after the titles of the shorter 

 papers which were not included either in the first or second volume of the collected papers. 

 In filling in these remarks on a prepared sheet Tail had got as far as the year 1870. I have 

 endeavoured to continue the work thus begun by Tail himself, giving in approximately 

 chronological order all his published papers and articles. Since by far the greater number of 

 these appear in the Proceedings of the Royal Society of Edinburgh, I have used the letters 

 Jt.S.E. to mean this publication. When a paper has appeared in the Transactions of that 

 Society the reference is to Trans. R.S.E. Any other journals are indicated by sufficiently 

 intelligible contractions. The two volumes of the republished Scientific Papers are referred to 

 simply as S.P. The first Sixty (LX) appear in Volume I and the rest from LXI to cxxxni in 

 Volume II. When any reference is made to Tail's books, the characteristic name of the book 

 is given in Italics.

 Soc., vii. Reprinted in Andrews' Scientific Papers.

4. Quaternion investigations connected with Fresnel's wave-surface. 1859. Quart. Journ.

7. Malhemalical Noles: A spherical nebula consisls of concenlric shells of uniform density; 

 find the law of the latter that to a spectator at a greal dislance the nebula may appear 

 uniformly bright. The densily in shell of radius r is inversely as J(a'~f 3 ). 1860. 

 Quart. Journ. Math., iv. 



8. Qualernion invesligation of Ihe polenlial of a closed circuit. 1861. Quart. Journ. Math., 

 IV. S.P., IV. Tail's Quaternions, 471. 



9. Note on a modification of the apparatus employed for one of Ampere's fundamental 

 experiments in electrodynamics. 1861. Jt.S.E., iv. S.P., v. 



10. Note on molecular arrangement in crystals. 1862. R.S.E., iv. Crystalline properties 

 illustrated by use of piles of marbles of equal size. A horizonlal layer may be arranged 

 in square or triangular order, and successive layers may be simply superposed or 

 inserted into interstices in the preceding ones. With interslilial arrangemenl Ihe square 

 and triangular order give same density.
