K. Sisido (This Jour., 1930, 6, Abst., 25) criticized the author's papers (Studies on the structure of vegetable fibres : This Jour., 1929, 5, Abst. 20, 25, 28, and 31), but the author can not assent to Sisido's views, and explains the author's opinion in the following : -
1, Spiral structure. Thin slice of pine wood shows fibres with remarkable spiral lines under microscope when swollen even with weak swelling reagents such as caustic soda solution, sulphuric acid & c. (G. Yamaha : Cell, 1929, 1st Ed., 185, Fig. 57) As in this case the fibres are fixed there is no fear of twisting of fibres, and as the swelling reagents are of weak nature it is sure that the degree of swelling is very low. From above we can judge that the incrination of the spiral line in the natural fibre does not differ greatly from that of the swollen fibre. The natural fibre with such remarkable spiral lines can be so neatly splitted parallel to the axis of the fibre as shown in Fig. 1, then how should we explain the structure of the fibre? The author believes that the theory, proposed by him (This Jour., 1929, 5 Abst., 31) that the fibre wall is generally not wholly of spiral structure, and the outer and inner cuticles and intermediate membranes (skins) are of spiral structure fibrils in other layers being parallel or nearly so to the fibre axis is most appropriate to explain the behaviour of the fibre.
2. Bead-like swelling. Sisido said that Lüdtke's proof for the occurrence of the crosswise skins (Querelememte) was insufficient which agreed with the result of the author's obseruation (Nakano, l. c.) while Sisido also has assumed the occurrence of a special skin at the place of stricture of swollen fibre which is quite the same in its idea with Lüdtke's theory!
Fig. 2 and Fig. 3 show examples of swollen fibres of bast from kozo. From these figures it is clear without any wordy explanation that the existence of the spira cuticle is a chief cause for the bead-like swelling. In Fig. 4 are shown mitsumata fibres swollen like sausage with a caustic soda solution after preliminary wetting with water while the same fibres show bead-like swelling by xanthation as shown in Fig. 5. Thus we can produce various swollen figures with the same fibres which being also one proof opposite to the crosswise (Lüdtke) or special (Sisido) skin theory.
