HELMINTHOLCKiY HELMINTHES CYSTICI. 479 



Bd. ii, pp. 367, 839) the Cysticercus celluloses occurs in 

 most of the muscles of man, but as it seems, only in the 

 voluntary muscles, and is found at the same time in the 

 substance of the heart and brain. The ossification of the 

 Cyst-worm has also been observed by E-okitansky. In the 

 brain, where the worm most frequently occupies the gray 

 substance, it would appear, when dead and ossified, to be 

 with great difficulty distinguishable from an ossified tubercle, 

 and, according to Rokitansky, the diagnosis of it can only 

 be established by the simultaneous presence of other living 

 Cysticerci. Difficulties of this kind in the diagnosis will 

 certainly be felt when no value is placed on the microscope, 

 by the aid of which the indestructible hooklets of the crown 

 of a Cysticercus long dead and destroyed are so readily 

 detected. A case of Cysticercus celluloses in the brain has 

 been related by Drewry Ottley (Med. Chirur. Transact, of 

 London, vol. xxvii, 1844, p. 12 ; or Lancet, 1843, Dec. 

 it. 368) as follows : a woman, 40 years of age, of lymphatic 

 temperament, resident in Exeter, had for many years been 

 a sufferer from emphysema of the lungs, with frequent 

 attacks of bronchitis. In the early part of 1838 she began 

 to complain of frequent giddiness and of a dull stupifying 

 pain in the head. These attacks returned again and again, 

 and after a time the giddiness became more constant and 

 the loss of memory and confusion of intellect more trouble- 

 some. 



In 1839, in addition to the above symptoms, she became 

 subject to fits, during which there was entire loss of con- 

 sciousness, with convulsion of the limbs. The character of 

 these attacks was different from that of ordinary epileptic 

 fits. They were less sudden, both in their invasion and 

 their termination, and the convulsions ceased and recurred 

 as often as eight or ten times in as many hours, the stupor 

 remaining during the intervals and after their cessation. 

 The recovery from them was slower also, for she would 

 often remain for two or three days in a stupified state. 



During the last twelve months of her life her sufferings
