as if not native, it must have long since been intro- 
duced from the north in the fir-trees so constantly im- 
ported. The specimens sent I obtained along with se- 
veral others, only two days ago, from bark of a foreign 
fir-tree which I chanced to pass as it was being prepared 
for a mast, in a living state, several being just emerging 
from the pupae, and others still larvae. I enclose a por- 
tion of the bark to show the kind of galleries the female 
makes, which it will be seen are horizontal, like those of 
the genus Hylesinus, (not vertical, as those made by the 
Scohjti,) though very often more or less oblique and 
curved. 
“ On Insects and their Larvae inhabiting the Human Body, 
accompanied by various Tables.” By the Rev. F. W. Hope, 
F.R.S., &c. 
In the discussion which took place upon the last-mentioned 
Memoir, the author observed that he considered the presence of 
these various species of insects, recorded to have been found in 
the human body, was accidental ; and that he did not consider 
any internal species to infest man alone. 
Dr. Blundell mentioned a case of which he had been wutness 
in Flanders, in which a girl, about nine or ten years old, had been 
greatly afflicted with fits, supposed to have been epileptic, and 
which had been treated by various Flemish physicians without 
effect. He had, however, tried vermifuge medicines, turpentine, 
and male fern, and in two or three days an enormous quantity of 
larvae, apparently of Musca domestica, was voided, and which 
were supposed to have been in the colon. 
Professor T. Bell admitted that it was w ith much caution that 
reports of this kind, of cases introduced into the surgical reports, 
ought to be received, in consequence of the constant impositions 
endeavoured to be practised upon medical men by ignorant pa- 
tients ; and he mentioned a case which had occurred at Norwich, 
in which some supposed worms ( Entozoa ) had proved, on exa- 
mination, to be only the genital organs of snails, of which the pa- 
tient had been in the habit of eating, but had been unable to 
digest the hard parts in question. He also mentioned a case of 
obstinate inflammation of the antrum of the jaw, from which very 
great quantities of blood worms, or larvae of Chironomus jdumosus, 
had been discharged. 
Professor Ow'en, in allusion to the powers of resisting the heat
