figure, in his collected memoirs, which is very correct, will convince 

 any one that it is almost impossible. M. Agardh, indeed, professes 

 that he is not quite certain whether an external membrane really 

 exists or not ; and his figures and observations seem to indicate that it 

 is really present. But even supposing his observations to have refer- 

 ence to alining membrane only, they differ greatly from those of pre- 

 ceding observers, except in cases where an evident and easy explana- 

 tion as to the apparent crossing of the constituent fibres exists, in the 

 circumstance that he finds these fibres not simply taking a uniform 

 spiral direction, but felted with one another in distinct fascicles, and 

 passing from one cell to those in immediate contact with it. — M. J. B.
