APPENDIX. 
Outline of Field of Work. 
(Proposed basis for work of R.M.S. Paper Section.) 
A. Standardization in 1 . Equipment and tools. 
2. Reagents. 
3. Methods of fibre analyses. 
4. Photo-micrographic records. 
B. Fil)re Analysis. 
1. Application of polarized light to fibre structures. 
2. „ ultra-microscope ,, 
3. Effects of beating on minute structure of fibres. 
4. Recognition of fibre defects (e.g. over-boiling or over- 
bleaching). 
5. Search for new reagents to differentiate type celluloses. 
6. „ „ similar fibres (e.g. 
the well-known difficulty of hemp and linen.) 
7. Association of fibre forms with physical properties. 
8. Valuation of new materials from structure of cellulose. 
9. Examination of paper without destruction of sample (for 
criminological evidence). 
10. Fungi and bacteria that attack cellulose (in paper deteriora- 
tion and purification of effluent waters). 
11. Chemical residues in pulp-paper, and their effect on paper 
deterioration. 
12. Action of writing-ink and printing-ink on paper. 
13. Botanical survey of fibrous structures of natural orders 
towards guiding searchers in the- field for new paper- 
making fibres. 
14. The association of physical properties of special papers 
with microscopical characteristics. 
C. Colloidal Physics. Chemistry of Cellulose . 
1. Structure of regenerated cellulose films and precipitates. 
2. Systematic examination of molecular condition of highly 
hydrated celluloses from various sources. 
3. Systematic examination of action of pure aniline dyes 
in (2). 
4. Preparation of crystallized cellulose (alleged to be already 
accomplished but unconfirmed). 
5. Attempted synthesis of cellulose.
