“It will be observed that the mean size of the cells, taking the mean 
of the two directions [mean of 3 and 4], is 0°11 mm., or less than 1/20 of 
the length of the fibres which measure 2°58. It can be understood, 
therefore, that such small particles as the oval cells will pass through 
a 70-mesh sieve of the washing drum, the holes of which would be 
about 0°2 mm., but the same sieve would of course retain the fibres 
proper. It will be observed also that the mean length of the fibres 
of the longest and strongest manila papers, which is about 2°85 mm., 
is only slightly in excess of that of the Hedychium fibre, but, as will 
hereafter be seen, the Hedychium, on account ot the peculiar nature 
of the fibres and the cells, is capable of producing a stronger and in 
many respects more serviceable paper. Moreover, the smallness of 
the Hedychium cells in comparison with the fibres enables the cells 
to fill the interstices between the fibres. Moreover, these cells, 
being of a flocculent, sticky and glutinous nature, act as a natural 
sizing material, e mechanically separated ard weighed the cells 
and fibres with the following results :—

unbleached paper, the cells of which have been entirely retained, 
we find to be as follows :—
