Selenite of lime and selenite of magnesia are slightly soluble 
in water. 
VILL. Biselenite of baryta dissolves with difficulty in water. 
The same is true of the corresponding salts of strontia and 
ime. 
Biselenite of magnesia is a doughy deliquescent uncrystalliza- 
le salt 
IX. Selenate of baryta is as little soluble as the sulphate.* 
Selenate ial magnesia is equal in est ap to the sulphate.t 
odi barium crystallized with an atom of water, is 
readily sclnbie in water, but does not ieccmins upon exposure to 
the air.{ It is deliquescent.¢ It is not fusible. 
Iodid of strontium is readily soluble in water.|| It is fusible 
below red heat. 
ssbeape iodid of calcium may be crystallized. m deli- 
quesces on exposure to the air,1 and fuses below red hea 
Hydrated iodid of magnesium crystallizes with difficulty, and 
deliquesces readily. 
Il Retiiaisnwiiti when heated by access of air, into metallic 
oxyds 
XI. “Todate of baryta with one atom of water is soluble in 1746 
parts of water at 15° C. and in 600 of boiling water.** — 
Todate of strontia with six atoms of water is soluble in 342 
parts of water at 15° and in 110 of boiling water.tt 
Iodate of lime with five atoms of water Soecluenl in 253 parts 
of water at 15° C. and in one hundred and ten parts of boiling 
ater. 
Iodate of magnesia is soluble in water, but has not been further 
examin 
XIL a mf barium with two atoms of water is unaffected 
by exposure 
Bromid of ae with six atoms of water loses its water at 
a feeble heat.¢ 
Anhydrous bromid of calcium deliquesces rapidly in the air. 
That with one atom of water crystallizes with difficulty from the 
solution of bromid of calcium 
XIII. Bromates of baryta, strontia, lime and magnesia crystal- 
lize with water, the first three with a single atom 
Bromate of baryta loses its atom of water not below 200° C. 
Bromate of strontia by 120° C., bromate of lime by 180° C. 
and bromate of magnesia at ordinary temperatures. 
XIV. Bromate of baryta dissolves in 130 parts of cold water.
