ganglia were formed. Some branches of nerves were seen passing 

 from the middle coat of the ossophagus into the lining membrane. 



After having completed the dissection of the oe sophageal ganglia 

 and nerves, the nerves continuous with them were then carefully 

 traced throughout the walls of the stomach from the cardia to the 

 pylorus. The peritoneal coat having been removed, a thin strong 

 tendinous expansion was seen underneath, covering the whole convex 

 border of the stomach and a great part of both the anterior and 

 posterior surfaces ; the removal of this fascia was necessary before 

 the nerves could be traced. 



If the preparation be now examined, numerous small nerves will 

 be seen proceeding from the abrupt termination of the par vagum at 

 the cardia, and distributed extensively over the cardiac extremity of 

 the stomach, to the muscular coat. Numerous branches of nerves 

 can be seen passing down between the muscular fibres of the outer 

 to the subjacent muscular coat, and largely distributed over the 

 fibres of this coat. 



The two trunks of the par vagum, divided into numerous branches, 

 can be seen passing forward to the coronary artery, which has been 

 cut across, with all the nerves proceeding from the semilunar ganglion 

 which united at the cardiac extremity of the stomach with these 

 nerves continued from the par vagum. 



The trunk and all the branches of the coronary artery are accom- 

 panied with nerves from the par vagum and semilunar ganglion, and 

 in this dissection the nerves with the arteries have been traced ex- 

 tensively to the lining membrane of the stomach. The branches of 

 the coronary artery are seen passing down through the muscular coats 

 generally, about midway between the smaller and larger curvatures, 

 accompanied with nerves upon which ganglia are formed ; and 

 numerous branches of nerves are seen passing to the muscular coats 

 from the nerves which accompany the arteries. 



I will not attempt further on this occasion to describe the ganglia 

 and nerves of the oesophagus and stomach displayed in this dissection, 

 from which it is obvious that there are two sets of nerves distributed 

 throughout the walls of the stomach, one to the muscular coats, the 

 other destined to supply the lining membrane. 



I have made elaborate dissections of the ganglia and nerves of the 

 whole oesophagus, stomach, alimentary canal, and lungs ; but of these
