of Anhydrous Liquefied Ammonia.

Metallic tin, stannous oxide, and stannic oxide were not affected. 

 Fused bichloride of tin was partly dissolved. Liquid tetrachloride of tin 

 was first converted into a solid substance with strong chemical action ; 

 the solid then dissolved freely, and separated again on evaporation of the 

 liquid. Metallic indium was unaffected. 



Fluoride of cadmium was not affected. Chloride of cadmium swelled, 

 but did not dissolve ; it contracted again on evaporation of the liquid. 

 Bromide of cadmium swelled somewhat, but did not dissolve. Iodide of 

 cadmium swelled greatly, and absorbed a large quantity of ammonia, but 

 did not dissolve ; it remained enlarged in bulk after evaporation of the 

 liquid. Carbonate of cadmium produced no effect. Sulphide of cadmium 

 was not visibly affected, but it imparted to the liquid a faint cobalt-blue 

 colour. 



Fluoride of zinc produced no effect. Chloride of zinc fell to powder, 

 swelled greatly, and did not contract after evaporation of the liquid ; it did 

 not dissolve. Bromide of zinc and iodide of zinc behaved like the chloride. 



Nitrocyanide of titanium, black oxide of titanium, titanic acid, zir- 

 conium scales, oxide of zirconium, sulphate of thorinum, glucina, chloride 

 of glucinum, carbonate of glucinum, sulphate of glucinmn, sulphate of 

 lanthanum, and niobic acid produced no visible effect. 



Oxide of cerium and fluoride of cerium were unaffected. Nitrate of 

 cerium dissolved slightly. Chloride of cerium swelled slightly, but did 

 not dissolve. Metallic magnesium was unaffected. Basic chloride of 

 magnesium dissolved slightly. 



Metallic calcium became covered -with an insoluble white powder, but 

 did not dissolve nor exhibit any other effect. Fused chloride of calcium 

 fell to powder, swelled greatly, but did not dissolve. Bromide of calcium 

 swelled a little, but did not dissolve. Metallic strontium behaved like 

 calcium. Metallic barium lost its metallic appearance, but showed no 

 signs of solution or other effect. Caustic anhydrous baryta was unaffected. 

 Nitrate of barium dissolved freely, and crystallized on evaporation of the 

 liquid. Chloride of barium swelled considerably, but did not dissolve ; it 

 remained enlarged in bulk after evaporation of the liquid. Baric sulphate 

 was not visibly affected. 



Metallic lithium produced strong action, and formed a deep indigo-blue 

 coloured fluid : as the liquid evaporated the metal separated, and ex- 

 hibited successive colours, first that of bronze, then of brass, and ulti- 

 mately colourless and brilliant like silver. Metallic sodium swelled, and 

 then behaved very much like lithium. Chloride of sodium dissolved 

 sparingly, and did not enlarge in bulk. Metallic potassium behaved like 

 lithium and sodium*. Nitrate of potassium was soluble, but not freely 



* These results agree with those previously obtained by C. A. Seely (see ' Chemical 

 News,' vol. xxiii. p. 169). Seely found lithium, sodium, potassium, and rubidium soluble, 

 and mercury, copper, thallium, indium, aluminium, and magnesium insoluble in anhy- 

 drous liquid ammonia.
