'194 Mr J. M. Macfarlane on the 



tlie protoplasm. An article by Flemming,* which has 

 recently appeared, will he referred to shortly. 



My attention having been given for some time to the 

 study of the vegetable cell, I found on examining the epi- 

 dermal cells oi OrnitJwfjalum 2^yramidale, L.,with Hartuack's 

 No. 4 eyepiece and No. 7 objective what seemed a well- 

 marked body inside the nucleolus of a cell. The idea sug- 

 gested itself to me, Might tliis be constant? and on care- 

 fully examining the others, such was found to be the case. 

 The epidermis was quite fresh, and had been stained in 

 alcoholic solution of eosin — an excellent stain for demon- 

 strating minute structure. Through the kindness of Pro- 

 fessor Dickson, I submitted them to a Hartnack's No. 10 

 immersion objective, and the new structure was well seen. 

 Numerous other flowering plants were examined, and in the 

 whole of these it was found to be present in the cells of the 

 epidermis, lamina, petiole, stem, and root, as also in Cryp- 

 togams such as Equisetum limosum^ Ghara, Spirogyra^ &c. 

 All the plants enumerated below show the new structure 

 well ; though in some, it is larger and more marked than in 

 others. 



Dicotyledons. 



Phaseolus multiflorus, stem, petiole, and lamina. 

 Veronica gentianoides, leaf epidermis. 

 Polemonmm ccerideum, petiole cells. 

 Rheum officinale, stem, petiole, and lamina.
