 , Bromide of Potassium,, KBr = 117*6. — The fourth part of 

 an equivalent, 29*4 grains, on being dissolved in water at 49°, 

 gave in two experiments an increase of 7*2 ; which gives for 

 the volume of the salt in solution 2S'8. The same quantity 

 of salt, immersed in turpentine at 63°. caused an increase of
