one of medium size imbedded in the muscles of the mid- 
cervical region. 
Internally. — On opening the abdomen an enormously 
enlarged spleen presented itself, containing in its structure 
a vast number of tumours closely packed together, the whole 
weighing over 17 lbs. The diaphragm and portions of the 
intestines were thickly studded with small deposits. The 
liver and kidneys had in each of them some half-dozen 
tumours varying considerably in size. The one in the psose 
muscles was pretty large. It is inclosed with the spleen. 
The bladder was much attenuated from frequent distension. 
The cuticular half of the stomach was unaffected, but in the 
villous portion of that organ were three circular excavations, 
extending quite through the muscular coat, about an inch and 
a half in diameter ; their edges were swollen, irregular, and 
gangrenous looking. They had an appearance of a tumour 
being formed in each and been separated by suppuration. 
I regret exceedingly that the messenger who brought in 
the parts I have forwarded neglected to bring the stomach. 
The chest was free from disease, with the exception of a 
pretty extensive cluster of the deposit in the fourth inter- 
costal space on the right side and towards the vertebrae. 
[The morbid specimens consisted of the spleen, and various 
pieces of partially consolidated tissue, apparently enlarged 
scirrhous lymphatic glands, having deposited in them a 
quantity of black material of a melanotic character. The 
spleen measured three feet in length, and weighed sixteen 
pounds. On cutting into it the increased size proved to be 
caused by a deposition of a large quantity of cancerous and 
melanotic matter].

Barley. — The Genus Hordeum , to which barleys are 
referred, though presenting but few species, is remarkable 
for the number and variety of its cultivated forms. 
The true origin of cereal barley is a problem difficult to 
determine. Professor Lindley, who paid great attention to 
this subject, and who obligingly sent us seeds of the forms 
presently to be described, has the following remarks upon 
the subject :
