Cupric suits ;— ( Irow well, Sulphate long slender blue 

 shoots. Better in weak than strong solutions. Chloride 

 green, rather thick shoots, lour to six inches. If both salts 

 together, the sulphate does not grow well. But a good 

 growth of sulphate will check the chloride. 



Ferrous sulphate and chloride— One of the most charac- 

 teristic growths. At first white, soon turning dark, about 

 three to four inches, interlacing slender shoots forming a 

 kind of bush. The chloride and sulphate are quite alike. 



Ferric chloride and sulphate— A great contrast to the 

 ferrous salts. The salts swell up and form red fungoid 

 growths, rarely reaching more than an inch in length. 



Chromic chloride and sulphate — Merely swells up or 

 may give a poor growth. 



Aluminie sulphate and chloride— The sulphate shews 

 little effect, scarcely giving distinct growths. The chloride 

 on the other hand, grows very quickly, forms thick soft 

 looking shoots which may grow to a foot in length. The 

 shoots are fragile, and the upper part often breaks off and 

 sinks to the bottom. 



Cobaltous nitrate and other cobaltous salts gives slender 

 violet shoots from two to four inches long. 



Nickelous sulphate and other nickelous salts. A great 

 contrast to cobalt. Usually swells up, but sometimes gives 

 a few short, thick stems barely an inch in length, of a 

 bright green colour. 



shoots, four to six inches, pale brown colour. Solution 

 becomes slightly coloured. In one case a thick shoot 

 expanding at the top was given. 



brandling, shoots up to six inches or more. Chloride grew 

 slowly at first, then very vigorously.
