would appear the most forcible argument, it was not on the Southport 

 plant in any case. 



Secondly. — From the examination of analogous productions, I am 

 led to believe that the stmctural and habitual " uniformity of its 

 growth " is such as to strengthen the idea that they are fungi, rather 

 than to prove them the roots of a phenogamous plant. 



Thirdly. — That although, when viewed partially dry, the substance 

 of the rhizoma and these fibres may " appear perfectly continuous 

 and identical," yet, when distended, every trace of such appearance is 

 lost; nor does a longitudinal section of the rhizoma display any signs 

 of an internal continuation of the fibres, which, if they were indeed 

 the fibrillae of the root, might be expected. Such is the case with the 

 claviform branches before mentioned, (fig. 1, a). 



Fomthly. — That in no instance, either sectional or otherwise, could 

 any "rupture of the cuticle " be produced, except such as already ex-
