he has added not a few from his own obser- 

 vation, together with several highly apposite 

 remarks ; and I am happy to find that he also 

 assents to, and, indeed, strongly confirms my 

 view both as to the agent which produces the 

 change and its consisting of organized lymph, 

 such as is usually elaborated under the influence 

 of inflammatory action, from which it is well 

 known that several varieties of foetal deformities 

 arise;* and it is a matter of every day ob- 

 servation how completely lymph so effused 

 will be converted into distinct firm threads, 

 uniting opposite serous surfaces, especially 

 those whicli move freely on each other, as the 

 pleura; and the peritoneal coverings of the ab- 

 dominal viscera.f 



From the cases referred to by Dr. Simpson, 

 I shall now notice three which appear more 

 particularly illustrative of the true nature of 

 this remarkable lesion, and confirmatory of my 

 original account of it. 



Zagorsky has described \ a. malformed foetus 

 of the fifth month, which, in addition to several 

 other deformities, was deficient of the right 

 leg, the thigh ending in a rounded and cicatrized 

 stump, in the centre of which was a small 

 projecting point: from this was prolonged a 

 slender thread-like membrane, strong in pro- 

 portion to its size, that ran directly across to 

 the left leg, which it encircled, a little above 

 the ankle, like a tightened ligature, see jig- 159, 

 and formed in it a depression of considerable 

 depth, while the portion of the extremity 

 below the ligature was, as well as the appended 

 foot, rather tumefied. From about the middle 

 of the transverse thread-like membrane a small 



Morgagni witnessed a fact of this kind; at body of an oblong form was suspended, which, 

 least his description of the appearance in a on exam j na tion, proved to be the right foot 

 monstrous foetus between the fifth and sixth perfectly formed, as its general outline and 



month, greatly resembles it, of which he says, 

 " All the limbs were in a very bad state, the 

 upper limbs from the elbows downwards ; 

 for to the arms, which were very short and 



five toes demonstrated, but not larger in size 

 than the foot of a foetus of the tenth or twelfth 

 week.

 Beclard, " that if this fcetus had remained in

 born with an amputated and cicatrized leg, the 

 remains of which might have been found in the

the other parts:"* and he afterwards, with 

 great reason, conjectures that the binding of 

 the cord round the leg may have been the 

 cause of the child's death, by interrupting 

 the circulation through it. It is a very ex- 

 traordinary fact, that in every one of these 

 cases, as well as in several others, the injury 

 was sustained by the Ic/t extremity. \

 of Edinburgh published an excellent paper on
