318 INCREASE OF THE TUBE. 



tioiisly pouring off the water to change it, the whole 

 part outside the joint being deprived of the support 

 of the dense fluid, fell down by its own weight to a 

 right angle with the other part, and so remained bent, 

 ever after the w^ater was repoured in, until I carefully 

 lifted it with the point of a pin to its original position 

 which it was then able to retain. This morning I 

 first perceived the creeping root, in the form of two 

 slender cylindrical shoots springing from one side of 

 the basal bulb. 



About the middle of this day the separation of the 

 medulla extended to within a short distance of the 

 tip ; this pait was quite filled with it in a very dense 

 condition, and from it the medulla descended in two 

 columns, separated from the walls of the tube, for 

 some distance downward. 



2Qrd. — The tube increases in length, but not in 

 diameter, (See fig. 8). the division of the medulla 

 into two slender lateral columns is complete, except 

 in the budding tip. The two rootlets have grown a 

 little, and one of them has sent forth an irregular 

 lateral plate of colourless shelly substance. 



Increase proceeded no further than this point; 

 though it was manifestly alive for a day or two longer, 

 during which the condensation of the granular pulp 

 still went on ; — but on the 96th the multitude of 

 active Infusoria swarming around the tube warned me 

 (though none of them seemed to have as yet attacked 

 it, and though no change in its appearance could yet 

 be detected) that death had ensued. It is remarkable 

 how immediately these minute creatures appear to 

 have notice of the decay of any animal matter in
