No. 12. THE TOTAL SOLAR ECLIPSE OF AUGUST 30, 1905. 



(From Nature, December 21, 1905, Vol. LXXIII, p. 173.) . 399 



This eclipse was viewed from a point where the central 

 line of eclipse cuts the east coast of Spain. Its duration was 

 over four minutes. The display of Protuberances at second 

 contact was very brilliant, but when the time of mid-totality 

 arrived not a trace of them was visible to the naked eye. 

 Therefore these Protuberances had an apparent height of 

 less than 45 seconds of arc. 



No. 13. ECLIPSE PREDICTIONS. (From Nature, October 19, 1905, 



Vol. LXXII, p. 603.) 402 



The predictions respecting the solar eclipse of August 30, 

 1905, as issued by the British Nautical Almanac and by the 

 French Connaissance des 7"emps are compared and their 

 want of agreement is illustrated by a Table. 



No. 14. THE SOLAR ECLIPSE OF APRIL 17, 1912. (From Nature, 



May 9, 1912, Vol. LXXXIX, p. 241.) 404 



This remarkable eclipse was observed from a northern 

 suburb of Paris. It was impossible to say whether it was 

 completely total or not. At the moments of second and 

 third contact the phenomenon called Baily's beads was well 

 seen. It was found impossible to offer a satisfactory 

 explanation of their nature, but they were clearly not due 

 to the interruption of the solar rays by the mountains of 

 the Moon. 



No. 15. THE PUBLICATION OF SCIENTIFIC PAPERS. (From 



Nat^tre, August 10, 1893, Vol. XLVIII, p. 340.) . . . 410 



A plan is sketched in this paper, whereby what is at 

 present inefficiently and extravagantly done by a multitude 

 of amateur publishers might at much less cost be efficiently 

 done by a central publishing office as a matter of business. 

 One great advantage of this would be that it would eliminate 

 the censorship of the Councils of the Societies. 



No. 16. THE ROYAL SOCIETY. (From Nature, January 28, 1904, 



Vol. LXIX, p. 293.) 4'3 



This paper is a summary of what the author said at a 

 special meeting of the Fellows, and deals particularly with 

 the practice of referring papers received from Fellows of the 

 Society, the effect of which is to render doubtful the authen- 

 ticity of the authorship of papers, as declared in the title. 



No. 17. NOMENCLATURE AND NOTATION IN CALORIMETRY. 



(From Nature, May 12, 1898, Vol. LVIH, p. 30.) . . 416 



The general principle advocated is that compound units 

 should be expressed by compound names ; and these should 

 be self-explanatory : thus, instead of calorie, we should use 

 gram-degree.
