604 PHILOSOPHICAL TRANSACTIONS. [aNNO 1683. 



Fig. 2, represents the worm I took out of a dog on dissecting it in the col- 

 lege theatre, which was about 5 feet long, and was alive. The small end shows 

 the head, as it appeared then to the naked eye, and is represented magnified by 

 the microscope in the 8th and gth figures. The protuberances at the sides are 

 the mouths. The broad end the tail, as in the first figure. 



Fig. 3, 4, 5, represent the figure of the head of this worm, which are given 

 us by Nich. Tulpius and Jo. Mich. Fehr. 



Fig. 3, represents the 2 heads, which Tulpius in the former edition of his 

 Observations gave to this worm, where he makes it a biceps. 



Fig. 4, is the picture of the head of this worm, which Tulpius gives in the 

 latter edition of his book of Observations. 



Fig. 5, shows the head of this worm, as it is delineated by Jo, Mich. Fehr, 

 which appears like a tricoccos. 



Fig. 6, is the figure of this worm in Cornel. Gemma. 



The following figures represent parts of this worm, as viewed by the microscope. 



Fig. 7j represents the protuberance or papilla about the middle of the edges, 

 and in it the orifice, which I take for the mouth of this worm. 



Fig. 8, is the head of this worm as it appeared in the microscope, in 3 se- 

 veral ones I took out of the body on dissection, wherein is observable a double 

 order of spikes or hooks; the longer arising from the centre, the other more 

 towards the edges, which at pleasure it can draw in or protrude, and with them 

 part of the neck also, as appears by the swelling out a little below, as it is very 

 curiously delineated, as well as the other figures, by my most ingenious friend 

 and accomplished gentleman. Rich. Waller, Esq. 



Fig. 9, is a side view of the head and the hooks in it, of the same worm.
