The Hypothesis that the Elements are Simple Bodies does not include all 



the Phenomena. 



The final reduction of the photographs of all the metallic elements 

 in the region 39-40 — a reduction I began in the early part of the pre- 

 sent year, and which has taken six months, summarised all the obser- 

 vations of metallic spectra compared with the Fraunhofer lines accu- 

 mulated during the whole period of observation. Now this reduction 

 has shown me that the hypothesis that identical lines in different 

 spectra are due to impurities is not sufficient. I shall show in detail 

 in a subsequent paper the hopeless confusion in which I have been 

 landed. I limit myself on the present occasion to giving tables show- 

 ing how the hypothesis deals with the spectra of iron and titanium. 



We find short-line coincidences between many metals the impurities 

 of which have been eliminated, or in which the freedom from mutual 

 impurity has been demonstrated by the absence of the longest lines. 



Evidences of Celestial Dissociation. 

 It is five years since I first pointed out that there are many facts
