•each other and, where there is a fractiire of the partition separating them, 

 It iassolves, thus ^resulting in the fomation of a single vacuole. Finally, 

 following the fusion of many of these vacuoles, there forms a single large 

 one bounded by a thick wall. 



Often, aside from the formation of the vacuole, one notices appearing 

 from one or more points of the surface of the body a refractile substance 

 of homo?;eneous appearance. If, now, one uses a solution of iodide of potas- 

 sium, one may be able to distinguish two substances vmich behave diversely; 

 one which colors intensely brown within and another which assrjnes a yellow 

 color peripherally. In the central part there sometiimes appear granules of 

 variable dimensions. 



Summarising, we observe the followin?:: That the body in q.uestion pos- 

 sesses a round form, homogeneous structure, and is colored 'oro^-ir. in a solutior. 

 of potassium iodide. On degenerating, it vacuolizes, its form becoming ir- 

 regular, V/ith reagents herein above re:&erred to one- can observe two distinct 

 substances. 



Eria stellata Lindl, 



In the leaves of this species, in each cell of the epidermis and of 

 the parenchyma, is to be noted in the cytoplasm, as well as in the nucleus 

 and in the leucoplasts, which are roundabout it, a colorless spherical body, 

 strongly refractile to light, and presenting the following reactions: 



Treated with a solution of potassium iodide, it stains yellow or brown- 

 ish accordins; to the degree of the concentration of the solution. 



Uith concentrated or dilute allcali, it dissolves and disappears rapidly. 



V/ith sulphviric acid and with other mineral acids in concentration, it 

 becomes invisible after a short iramersion.
