ficulty delivered of a dead child, there were found two large globose tumors, 

 depending on the left testicle, and may rather be called* preternaturally-grown 

 eggs, or parts of the extended ovarium : both of them lay in the pelvis, under 

 the womb, and so hindered the egress of the foetus, which was large and well 

 grown. They were covered with a thick membrane, which had its veins and 

 arteries as conspicuous as those are in the urinary bladder. That nearest to the 

 testicle was the least, of the size of a cocoa-nut, which had in it a fatty sub- 

 stance, not fluid, of the colour of the yolk of an egg, and in the midst of it 

 a lock of hair, which when it was freed from the grease, appeared of a flaxen 

 colour : the fat itself crackled in the fire, melted and took flame like lard, and 

 in a spoon over a candle would boil and smoke, excepting some small grumous 

 parts. In the midst of the membrane was a hard and knotty substance, in which 

 lay a small bone of a strange shape, with a periosteum on it, which was hard to 

 separate from it. The bone is hard, white, and somewhat larger than the largest 

 of the bones in the meatus auditorius. 



The other tumor was thrice as large as the former, and about two inches dis- 

 tant from it, yet connected to it by a strong membrane of the extended testicle. 

 Opening it, there sprung out a more white and liquid sort of grease; but in the 

 middle was as thick as the former, and of the colour and constitution of live 

 honey ; for which cause it may be called a meliceris; though the inflammability, 

 both of this and the other, makes them both steatomata. In the midst of this 

 lay enveloped a large lock or two of hair, variously entangled like those the 

 countrymen call elfs-locks, which are a species of the plica polonica : the colour 

 was of a blackish brown, and the quantity four times as much as the former. 

 Some part of this hair was long, and evidently grew out of the inward parts of 

 the membrane, in which it was radicated, and from whence it was plucked. 

 This fat was more inflammable than the other, neither did it crackle in burning 

 as the former, and left fewer spots in the spoon. In the duplicatures of this 

 membrane also was a lump which contained another misshapen bone, very hard 

 and hollow, covered with a skin like a periosteum without, and the dura meninx 

 within : so that it is hard to say, whether nature was forming a tooth with part 

 of the jaw, or the whole cranium.
