200 ENTOZOA FOUND IN MAN. 



In other cases, the existence of cysticerci in the 

 brain was not manifested by any particular sign, 

 until the symptoms of an acute affection of that organ 

 made their appearance. In these instances, severe 

 headache, convulsions of the extremities and of the 

 lower jaw, great rapidity of the pulse, difficulty of 

 breathing, exhaustion, and coma followed one another 

 in quick succession, and the death of the patient 

 occurred at the end of a few weeks, or even days. 



Vesicular worms which are developed in the 

 spinal canal, or which find their way into it from 

 without, give rise sooner or later to the phenomena 

 which result from gradual and increasing compression 

 of the spinal cord, arising from any cause whatever ; 

 so that they do not consequently differ from the 

 symptoms which are observed when any foreign body 

 exists in the spinal cord or canal. 



There will be loss of motion and of sensation in 

 the parts which are situated below the seat of the 

 tumour, constipation, and retention or incontinence 

 of urine ; and these sjonptoms are commonly pre- 

 ceded by pain, convulsive attacks, and a sense of 

 tingling and irritation in the extremities. 



The pain may be very acute, and be confined to 

 the part occupied by the tumour, or it may follow 

 the course of the large nervous trunks, and come on 

 in paroxysms, accompanied by cramps or spasmodic 

 convulsions in the limbs, which soon lose both sensa- 

 tion and the power of voluntary motion. 



The paralysis generally attacks the lower extre- 

 mities, the bladder, and the rectum, but it may, of 

 course, extend to other parts if the tumour be 

 situated near the upper portion of the spinal cord ;
