The dried material in sample C consisted of man-made, synthetic and natural fibres
with some hairs, fragments of plant material, including stem and leaf fragments and a
few feathers (Figures 13 and 14). A seed (Figure 15), a moderate level of fine-
grained sediment and a single insect fragment (Figure 16) were also found.
Like sample, A the feathers did not appear to be flight feathers and were therefore
considered most likely to have originated from stuffing in pillows, cushions, furniture,
Compound Light Microscopy Examination
Examination of typical subsamples mounted on glass slides demonstrated sample
A to contain a few hairs (Figure 17) that were considered likely to have originated
from a small mammal e.g. cat, rodent, etc. Some fragmented pollen grains were also
found (Figure 18). Figure 19 shows mixed textile fibres and a cat (probably) hair.
Examination of a stained subsample of the very fine-grained suspended sediment
in the retained liquid from this sample showed there to be a relatively high level of
rod-shaped bacteria present (not shown).
Examination of similar slides from sample B demonstrated the presence of red and
yellow dyed hairs. These hairs were not human and were, therefore, considered
likely to have originated from the carpet or other textile. A relatively low level of
bacteria were found in the very fine-grained suspended sediment in this sample,
which consisted of birefringent mineral grains, extremely fine-grained sediment,
some optically dense particles and a low level of starch (Figure 20).
