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-rjlobulin. 



Boiling clears somewhat; no coagula. 

 Sodic chloride (0.75 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. 

 Metaphosphoric 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 (0.75 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. 

 Metaphosphoric 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 C., 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. 



6. No precipitate with C0 2 . 



7. No precipitate with ferric chloride. 



8. No precipitate with cupric sulphate.
