 Connate which yields an atomic weight nearest to 122 possesses 

 distinctly different physical properties from the formates obtained 

 from oxides of much higher or much lower atomic weight, some 

 • lireet experiments were made. To test the question whether this 

 lesult was due to the crystallization together of the higher and 

 lower formates, a mixture was made of the formates of yttrium 

 and terbium, in three solutions, each containing different propor- 

 tions. One of these solutions yielded rhombic crystals exactly 

 like those previously obtained. Hence it appears that the for- 

 mates of terbium and yttrium are capable of en stallizing together 

 in a form ascribed to philippium.— ./. Clnn>. Soc ., xli. 277, June,
