ig6 Mr. Home's Account of a small Lobe 
the cavity of the bladder. These tumours, as they obstruct 
the passage of the urine, have attracted the attention of all 
anatomical surgeons, from the time of Morgagni to the 
present day. Their appearance has been accurately described, 
and specimens of them in different degrees of enlargement 
are preserved in every collection of morbid parts. The atten- 
tion of surgeons has been naturally called to what is of the 
greatest consideration, the appearances they put on, and the 
symptoms they produce : but the particular circumstances in 
the natural conformation of the gland, which dispose it to 
form these tumours, have never been examined. Morgagni 
says, “ These caruncles were found to grow out in the very 
“ middle of the upper and internal posterior circumference of 
“ the gland; but whether these things happened by chance or 
“ otherwise future observations will shew.”* 
From these expressions, it is evident that Morgagni had 
no idea that there was any conformation of the prostate 
gland, that could account for this tumour, and believed that 
it arose from the surface of the body of the gland. 
Mr. Hunter, in treating of the enlargement of the prostate 
gland, says, “ From the situation of the gland, which is prin- 
“ cipally on the two sides of the canal, and but little if at all 
“ on the fore part, as also very little on the posterior side, 
“ when it swells it can only be laterally ; whereby it presses

attulimus, et nostra omnia attente inspicias, cuncta in senibus fuisse animadvertes : 
Ita nostra omnia, in quibus carunculee initium fuit, hanc in medio ipso posteriori 
interni summique glandules ambitus excrescentem obtulisse : casune hasc cuncta, an 
secus, futures ostendent observationes. Morgagni de Sed. et Cans. Morb. lib. iii.
