 at King's College Hospital, and he suffered from epileptic fits, one 

 of which caused his death in the month of January, 1855. A sectio 

 cadaveris revealed the presence of numerous small cysticercal hyda- 

 tids in the brain, near the surface. The conditions presented by one 

 or two of the Oysticerci, with and without their investing capsules. 



Fia. 49. — a, Portion of the brain with a cjst in situ, showing the capsule surrounding it ; 

 b, similar section, with a second capsule ; o, cyst removed from its capsule, to exhibit 

 its vascular character; d, the same torn open, and displaying the more delicate hyda- 

 cyst within, which partially protrudes itself ; e, the little bladder-like Cysticercus en- 

 tirely separated ; a dark spot marking the position of Goeze's lantern {receptaculum capitis) ; 

 /, the same partly unfolded ; g^ the unrolled head, neck, and body of the Cysticercus, separated 

 from the caudal vesicle in which it was lodged, and flattened under a thin portion of glass ; it 

 exhibits an opacity about the head and numerous conspicuous transverse lines ; Ti, portion of 

 the same, showing that the transverse lines are due to tolerably regular foldings of the integu- 

 ment ; it also exhibits the transparent epidermis in profile, a number of dehcate lines running in 

 the long axis of the segments, and a series of nucleated vesicles (calcareous corpuscles) ; i, dis- 

 section of the capsule of another specimen, exposing the vascular cyst in situ; k, isolated cyst, 

 with a vessel ramifying upon its external surface. — Hulke.

 were several specimens of the Cysticercus present I have since had
