The oleose substance is soluble in 5 per cent alcohol, in ether, and 

 in chloroform. It is insoluble in acetic acid, in chloral cliydraiS; it stains 

 with Sudan III and with Scarlet S aaid turns black when treated with osmio 

 aoidv 



The development of these bodies is comparable to that of the elaioplasts 

 of the preceding species. In fact, in epidermal cells in process of division 

 of the growing point they do not participate in the phenomena of kariokinesis. 

 They appear at first to turn around the nucleus like little refractile spheres 

 which, moreover j increase in number as they progress in their development, 

 increasing slightly in vol"ume. In the advanced stages of their development 

 t^ey are of a granulose structure (Pl, XIV, figs. 2, 5) and present in their 

 Intetipxunumerous vacuoles* TT/hen the epidermal cells have passed beyond the 

 stage of their complete development it is difficult to find in them any 

 elaiojplasts because they, degenerating, have disappeared* 



From the results here given regarding the elaioplasts found in the 

 Malvaceae and those hitherto found in the Monocotyledoneae, they resemble 

 these latter perfectly in position, in form, in development,, in structtire, 

 and in chemical compos it ion»
