_ IX. A Case of extensive Solution of the Stomach by the 
Gastric Fluid after Death. By John Haviland, MD. Vice-Pre- 
sident of the Cambridge Philosophical Society, and Regius 
Professor of Physic. 
The subject of this case was a young man of about 20 years 
of age, who died of fever, but had previously enjoyed good 
health. The body was opened 12 hours after death, and the 
stomach on being examined after its removal from the body, 
afforded the following observations. The mucous membrane 
appeared to be more red and vascular than usual throughout its 
whole extent, and here and there were small spots of what 
seemed to be extravasated blood, lying below the mucous coat ; 
for these spots were not to be washed off, nor to be removed 
by the edge of the scalpel. There were two holes in the sto- 
mach, the larger very near to the cardiac end of the small curva- 
ture, and on the posterior surface : this was more than an inch 
in length, and about half that breadth. The other not far from 
the former, also on the posterior surface, about the size of'a six- 
pence. The edges of these holes were smooth, well defined, and 
slightly elevated. The coats of the stomach were thin in many 
other spots, and in one particular nothing was left but the peri- 
toneum, the mucous and muscular coats being entirely destroyed. 
The hole in the diaphragm was through the muscular portion, 
where it is of considerable thickness, and was large enough to 
admit the end of the finger. There was no appearance of ulce- 
ration or of pus adhering to the edges of this perforation of the 
diaphragm. Dr. Haviland concludes with stating the reasons 
which induce him to*believe that owing to the activity of the 
solvent power of the gastric juice, it sometimes not only corrodes 
the parietes of this organ itself, but even the thick muscle of the 
diaphragm, and that within the space of 12 hours after death ; 
and he states the appearances presented by this case confirm 
this opinion, which originated with Mr. J. Hunter. 
X. On the Physical Structure of the Lizard District in_the 
ated Cornwall. By the Rev. A. Sedgwick, MA. FRS. 
MGS. Woodwardian Professor, &c. &c. 
In this paper, the author describes at considerable length a 
portion of the coast of Cornwall, which has always excited the 
attention of geologists. We regret that our limits will not allow 
us to do more than give a recapitulation of the statements which 
it contains, and this we shall doin the author’s own words : 
“« From a general review of the facts already stated, it appears 
that a section made from the heights above Constantine to the 
mouth of the Helford river, and from thence to Old Lizard Head, 
in the general direction of the coast, would exhibit a series of 
formation nearly in the following order: 
“1, Granite containing an excess of mica atits junction with 
the slate. 
“2. Clay slate.
