the paper-making qualities of Hedychium coronarium and the 
following extracts are taken from a copy of the paper sent to Kew 
by the courtesy of the authors. . ; 
A chemical analysis of dried specimens as, received was made 
with the following results :—

“We discovered that the pith cells, which can be retained or not, 
according to requirements, possess very peculiar qualities, If taken 
alone, the unbleached cells i 
which the cells are retained, as will be seen, gives higher ‘ breaking 
lencths’ than any manila paper that we have so far had the 
opportunity of examining. The oval cells, therefore, ‘ parch- 
mentize,’ strengthen and size the sheet. 
“The pulp, after boiling in soda and beating, if examined under 
the microscope in the presence of chloriodide of zinc shows :— 
(a) Oval cells stained blue. 
(6) Long wide fibres something like chemical wood, stained blue. 
(c) Numerous shorter and solid-looking fibres, stained ellow. 
(d) Small epidermal cells attached to one another, stained 
yellow.” oe 
The length of fibres is given in a table which is not reproduced 
here. The means of the results of measurements under the 
microscope of numerous fibres are as follows :— 
“1, Hedychium fibres, unbleached, not beaten, 2°61 mm, 
“2, Hedychium bleached, not beaten, 2°56 mm.
