workings—although the pumping brought up one thousand gal- 
lons per minute, the miners were in such danger of being drown- 
ed, that several left the employment. In the latter end of July, 
the sea at length broke in, filling the mine in all its parts, in little 
more than two hours, and destroying twenty miles of railway.. 
On one side of the Camperdown dyke, which ranges through the 
mine, not a soul was saved, but several escaped from other parts ; 
and one individual, an Irishman, called Brennagh, had not only a re- 
markable escape himself, but saved three others by his intrepidity. 
Prof. Sedgwick related to the Section this man’s story, which was 
so singular, and told with such a mixture of the serious and ludi- 
crous—often in the language of the man himself—that it is im- 
possible to convey to the reader an idea of the effect produced on 
the audience. A remarkable fact in the escape of one of the in- 
dividuals rescued by Brennagh was, that he was actually blown up 
the last open shaft of the mine by the enormous force of the air, 
the noise of which was heard at a considerable distance in the 
country. The first notice to Brennagh of the accident, was an 
unusual undulation of air in the galleries, which made him sus-. 
pect that all was not right, and he took the precaution of moving 
near to an air passage in the dyke, which he had been permitted 
to use: he was thus enabled to save himself and his companions. 
At the suggestion of the Professor, a subscription was made in the 
Section for Brennagh, which amounted to 34/. 
Intestinal Worms.—Dr. Richardson communicated a paper 
from Dr. Bellingham, on the frequency of the occurrence of Tri- 
chocephalus dispar in the alimentary canal. The author alluded 
to the difficulty of accounting for the origin of animalcule in the 
human body. To say that they were secreted or not secreted by 
the tissues of the body, was premature, as we knew so little of 
secretion itself. Although in some instances parasitic animals 
produced injurious consequences to the animal they infested, yet. 
in many others no injury was experienced. The 'Trichocephalus 
was found in the majority of human beings, but produced no ill 
consequences. The genus belonged to the division Nematoidea 
of Rudolphi, and contained eight species. The Trichocephalus 
dispar was mostly found in the cecum, but sometimes oceupied 
the colon and small intestines. It had been found at Géttingen 
in those who died of fever, and at Naples in those who died of | 
cholera; at nd. was there supposed to be the cause of that cane
