426 Mr. Prideaux's Continuation of the Table of Atomic Weights, 



(a.) Alumina, glucina, zirconia ; oxides of antimony, bis- 

 muth and mercury : see the notes on the respective metals 

 appended to the Table of undecomposed bodies. (See supra, 

 p. 163, et seq.) 



(b.) Oxide of chrome. — Thomson, correcting his number 

 for this oxide in the First Principles, makes it (Ann. Phil, 

 second series, vol. vi.) chrome 1 atom, oxygen 1^ atom : a for- 

 mula, of which even its high authority does not demonstrate 

 an advantage commensurate with its verbal inaccuracy. In 

 signification it corresponds with that of Berzelius. 



(c.) Oxides of iridium, osmium, palladium, platinum and 

 rhodium, are taken from the paper of Berzelius quoted in the 

 note on these metals appended as above referred to ; but with 

 adjustment to the mean weight of chlorine. 



(d.) Peroxide of uranium. — The constitution assigned by 

 Berzelius to this oxide seems to me rather confirmed than 

 invalidated by Thomson's experiments.
