Fig. , 



13, 14, 15. — Sublimates of strychnine — 13, fiue-feathered crystal (-g-^go^h 



grain) ; 14, crystals in forms a and b, found in the same sublimate ; 



15, sublimate from a deposit from a solution in benzole. 



16. — Sublimate of strychnine treated by a solution of bichromate of 

 potash (voo) ; plates of various forms, single and in groups. 



17. — Sublimate of strychnine, treated by a solution of carbazotic acid (2^)5 

 showing hooks or claws, scattered and grouped. 



18. — Sublimate of morphine, treated with the same reagent, showing part of 

 margin of dry spot. 



19. — Sublimate of brucine, treated with the same reagent, showing root-like 

 forms. 



20. — Sublimate of morphine, curved elements contrasting with the nearly 

 straight elements of strychnine (fig. 13). 



21. — Globular sublimate of morphine, showing crystalline forms in the 

 globules. 



22. — Morphine with hydrochloric acid {-io). 



23. — Morphine with spirits of wine. 



24. — Morphine with liq. ammonise.
