2 Mendeljeff predicts (Liebig's Ann. Suppl. 1870-72, p. 202) that Ekasilicon 

 will boil somewhat below 373°. 



3 Prom this point onwards the values given are only rough approximations. 



The melting-points and boiling-points which have been cal- 

 culated for some of the substances cannot be determined in 

 the ordinary way, as they undergo decomposition below their 

 melting-point or boiling-point. 



Confirmation of Results obtained by the above Method. — The 

 results given in Table IX., though not previously printed*, 



* Though not printed, they were given in a paper read before the Royal 

 Society in June 1879, an abstract of which was published in the ' Pro- 

 ceedings ' in the same year.
