Chloride and Amide of Mercury, HgCl + HgAd = 254*5..^ — 

 The excellent researches of Kane, so often alluded to,^ have 

 shown that the above formula represents the composition of 

 w^hite precipitate. It must be dried by a pretty strong heat, 

 to get rid of all its hygrometric water. On projecting 63-8 

 grains, the fourth 'of an equivalent, into water, an increase of 

 11-2 was obtained in two experiments; this gives 44-6 as the 

 specific volume /3^ ^.fm^Wh^^^^^^^'^^^i^^

2HgO = 473-3. — This yellow compound was made in the 

 usual way, by boiling white precipitate with water. On 

 throwing 59*2 grains into w-ater, the rise was 8*2 in one ex- 

 periment, and 8-3 in another. ^'"^^ ' " '' \^.i^,^;^^2
