spirals. The last formed, or forming, of these spirals is seen at (3, together 
with its structure, y. Represents the nuclei. Spirals were noticed be- 
tween a and (3, but they are not represented in the figure (pars. 35,38). 
Fig. 23. Chick in ovo ; twelfth (?) day of incubation. Sketch of a muscle-tube. 
a. Membrane. (3. Nuclei in the centre of the tube : very near together, 
y. Spiral. e>. Another spiral appearing to arise from some of the nuclei. 
See the description of fig. 22 (3. 
Fig. 24. Rabbit. From the cortical substance of the cerebrum. Blood-red cell 
arranged to form tubes. These cells are in outline excepting two, in 
which the contents were seen to consist of discs, or ring-like objects, 
arranged with regularity, like those in muscle, fig. 45. 
Fig. 25. Sketch of mould on a ripe berry ( Rubus fruticosus, Linn.) that had been kept 
a few days. Cells having arranged themselves in a necklace-like form, 
have elongated, and spirals are forming in their interior (par. 67). 
Fig. 26. Sketch of mould from cheese, a. Granules, escaped from containing bags. 
(3, (3. Tubes, still exhibiting the septa between the cells, by the union of 
which they were formed. One of them is branched. At y, in one of the 
tubes, are cell-like objects arranging themselves in lines. S. Rings now 
visible, e. Smaller rings, or interlacing spirals. Spirals having been 
formed, they have become very much elongated, so as to appear nearly 
horizontal (par. 67). 
Fig. 27. Mushroom. Sketch of germinal granules, of a reddish brown or purple 
colour, from the hymenium. In such granules a nucleus is seen, often 
consisting of two parts. Around the nucleus are other objects, smaller 
and having a less refractive power. These are not represented, except 
in a. (3. Granule, apparently younger than the rest (see par. 90). 
Fig. 28. Tadpole, about 5'" or less. From the tail. Outline of cells, which are 
altered blood-corpuscles, arranged in a line to form the first muscle-cy- 
linder or tube (par. 42). 
Fig. 29. Tadpole, about 5^"'. From the tail. Corpuscles having the appearance of 
young blood-corpuscles, as viewed along with many others in a group, ap- 
parently escaped together by the rupture of one parent corpuscle. Cells 
such as those in fig. 28 are filled with young corpuscles or discs, appa- 
rently of the kind represented in the present figure (par. 42). 
Fig. 30. Tadpoles, 4|"' to 5"'. From the tail. Fragments consisting apparently of the 
contents of objects such as those in fig. 28 ; the discs (fig. 29) in which 
have arranged themselves in columns. The fragments are for the most 
part in outline, except (3 . y Presented a membranous appearance at the 
surface, not seen in a and (3 . a Was of such length as to appear like 
two of the cells in fig. 28, not separated from one another, &. Appear- 
ance presented by one of the compound discs in the columns (par. 42).
