THE CHEMISTRY OF VENOMS. 15 



Potassic sulphate — soluble ; solution rendered absolutely clear by boiling. 

 Calcic chloride — soluble ; solution rendered clearer by boiling. 

 Acetic acid (5 per cent.) — insoluble. 

 Acetic acid (glacial) — insoluble ? 



Copper-venom-globulin. 



Boiling — clears somewhat; no coagula. 

 Sodic chloride (0.15 per cent.) — insoluble. 

 (10 " ) — insoluble. 



(crystals) — insoluble; boiling partially clears without the formation of any 

 coagula. 

 Carbonic acid — somewhat soluble; boiling clears absolutely. 

 Sodic carbonate — very soluble; boiling no effect. 

 Hydrochloric acid (0.4 per cent.) — very soluble. 

 Melaphosph.or.ic acid — insoluble ; boiling appears to clear slightly. 

 Orthophosphoric acid — very soluble. 



Sodic metaphosphate — insoluble; boiling clears somewhat. 

 Sodic orthophosphate — somewhat soluble ; boiling clears beautifully. 

 Potassic sulphate — insoluble ; boiling clears slightly. 

 Calcic chloride — slowly dissolved; not so soluble as water-globulin; boiling gives a slight 



cloudiness. 

 Acetic acid (5 per cent.) — soluble. 

 Acetic acid (glacial) — soluble. 



Dialysis-venom-globulin. 



Boiling — clears almost absolutely without the apparent formation of coagula; boiled solution 



precipitated by saturation with crystals of sodic chloride. 

 Sodic chloride (0.Y5 per cent.) — insoluble. 



(10 " ) — somewhat soluble; dissolves slowly, forming a slightly turbid 



solution ; boiling seems to clear some without the formation 



of coagula. 

 Carbonic acid — very soluble ; slight turbidity by boiling. 

 Sodic carbonate — very soluble ; boiling no effect. 

 Hydrochloric acid (0.4 per cent.) — very soluble. 

 Melaphosphoric acid — slightly soluble ; yellowish tint ; boiling clears slightly with the formation 



of coagula. 

 Orthophosphoric acid — very soluble ; boiling no effect. 

 Sodic metaphosphate — insoluble. 

 Sodic orthophosphate — soluble ; boiling no effect. 

 Potassic sulphate — somewhat soluble. 



Calcic chloride — very soluble, form a beautiful clear solution ; boiling causes slight turbidity. 

 Acetic acid (5 per cent.) — soluble 

 Acetic acid (glacial) — soluble 



Moccasin Peptone. 



1. Readily dialysable. 



2. Not immediately coagulated at a temperature of 100° O, but gradually coagulated by pro- 

 longed boiling (see Cobra peptone, p. 17). 



3. Reaction with the xantho-proteic test (nitric acid and ammonia) 



4. Reaction with Millon's reagent (mercuric nitrate) 



5. No precipitate with weak or strong nitric acid, 

 fi. No precipitate with C0 2 . 



1. No precipitate with ferric chloride. 

 8. No precipitate with cupric sulphate.
