DR. MARTIN BARRY ON FIBRE. 
Fig-. 74. Flax, dividing and subdividing into filaments (“ fibres”). At a, and in part 
of £5, a membrane-like investment prevented the structure from being 
seen (pars. 69, 62). 
Fig. 75. Similar division of flax. The same fasciculus presented the three states a, 
ft 7 (par. 69). 
Fig. 76. Similar division of flax ; the states a, (3, y and &, having been seen in the 
same fasciculus (par. 69). 
Fig. 77 - Sheep. From the spinal chord-}-. Sketch of a fasciculus of nerve. At a, a 
spiral crosses the entire fasciculus : at (3 , one half of the fasciculus is 
crossed by another spiral (par. 39). 
Fig. 78. Sketch of mould from a ripe berry ( Rubus fruticosus, Linn.). It presents a 
fasciculus of filaments, surrounded by a spiral filament (par. 67). 
Fig. 79. Tadpole, about 5'". Portion of muscle. From the tail, presenting interlaced 
spirals (par. 45). These are more transversely curved at the upper part, 
and the object (filament) is therefore wider here than below, where the 
direction of the curves is more oblique. At a part still lower than the 
figure shows, the object was as broad as at the upper part of the figure : 
and here also there was a corresponding change in the direction of the 
spirals (par. 51). 
Fig. 80. Sheep. From the spinal chord-}-. Sketch of spiral filaments (a), surrounding 
filaments having a more (yet not perfectly) longitudinal direction (/3). 
Internal to the latter, was a broad “ band-like axis” (y), exceedingly de- 
licate, and consisting of very minute filaments, such as those in fig. 81. 
(par. 36). 
Fig. 81. Sheep. From the spinal chord -}-. a. Dots, showing the curves of a spiral. 
These curves presented great irregularity in their direction, which has 
not been imitated in the figure. (3 . Delicate “ band-like axis” (corre- 
sponding to that in fig. 80), consisting of minuter filaments. Spirals 
seen in the latter (par. 36). 
Fig. 82. Sheep (?). From the grey substance of the cerebellum. Sketch of a fasci- 
culus of nerve, consisting of two halves. Two spiral filaments are seen, 
the one surrounding half of the fasciculus, and the other surrounding the 
whole of it. The latter spiral is removed from the fasciculus at the 
lower part (par. 39). 
Fig. 83. Sow Thistle ( Sonchus oleraceus, Linn.). From the root. Sketch of two 
interlaced spirals, invested by something like a membrane (par. 83). 
Fig. 84. Tadpole. Sketch of two interlaced spirals in muscle, forming a very large 
filament (par. 45). Between a and (3, the filament is twisted ; present- 
ing here, therefore, a thinner part, its edge.
