Mr. Walter Morris exhibited two slides of Pediculis 
pubis (Linn.), a parasite; one showing the adult female, with 
the large ovum, one-third the size of the abdomen, in situ ; 
the system of tracheae, with eight spiracles on each side ; 
four broad flaps or suckers projecting from each side of the 
abdomen, for adhering to a flat surface ; and the two hinder 
pair of legs, each terminating in a formidable toothed claw, 
folding upon a socket, for grasping. By polarized light the 
bands of muscles, which were too transparent to be clearly 
shown by ordinary illumination, were very distinctly brought 
out, especially the flexors and extensors in the legs. The 
other slide was a specimen in the pupa, or intermediate 
state, and showed the perfect insect, complete with claws, 
antennae, &c., within the outer skin of the pupa, ready for 
the latter to be thrown off. 
Mr. Bichard Heys communicated some “ Observations on 
Anguillula tritici, obtained from wheat of various harvests.” 
They related to some successful experiments which had been 
made on vibriones contained in grains of wheat belonging to 
the harvests of 1859 and 1860, grown in Gloucestershire and 
Northumberland. In most of the experiments the vibriones 
were revived by moistening the grains in tepid water, soon 
after which the vibriones were seen moving about freely, or 
massed together in entangled clusters. The vibriones failed 
to make their appearance in some grains of Egyptian wheat 
which were grown in Gloucestershire in 1849. In the 
“ Micrographic Dictionary” it is stated that these organisms 
will revive after having been kept in a dry state for more 
than five years, but the observations now recorded prove 
that they may be revived after being kept for more than 
twice that length of time. 
A paper, entitled “Bemarks on the Flora of Cheshire; 
with Notices of the New and Barer Plants of the County,” 
was read by Mr. Spencer Bickham, Jun. An extract will 
appear in the next number of the “ Proceedings.”
