observed under the conditions just indicated, present here and 
there colorless lacunz, at least in certain species of plants. In 
the second case, the walls of the cells are seen to stand out white 
upon a colored ground; thecanals which traverse these walls are 
then visible because they are colored the same as the fundamental 
protoplasm itself.* AG 
4. Injection into organs. JI also tried to inject (slowly under 
pressure) into the organs to be studied a liquid capable of color- 
ing the protoplasm; I then made cross sections of these organs. 
The injection rarely succeeded, but when it took lace in a suffi- 
ciently uniform manner, this process led to a result identical with 
the preceding. 
IV. This unity (ensemble) of facts shows at least that in a 
great number of cases the cell walls permit the passage of proto- 
plasm through narrow openings ; so that in the tissues of a given 
plant, where up to a recent date we have only observed a multi- 
tude of small protoplasmic masses entirely isolated, there is m 
reality a single enormous protoplasmic mass. : 
It has seemed to me especially interesting to prove the exist- 
ence of this structure in various parts of the same plant. For 
this purpose I have employed the box (Buzus sempervirens). 
Applying the methods 1, 2, 3, above mentioned, I have roved a 
continuity of the protoplasm in the stem and in the leaves of this 
shrub. From my investigations Iam led to believe that in this 
Species the protoplasm pursues, through incomplete cell walls, aD 
uninterrupted course from the roots to the extremities of the 
leaves. Ficus elastica shows an analogous structure. The bear- 
ing of these facts on vegetable physiology and on natural phi- 
losophy will be considered in the near future.
