226 ENTOZOA. 



neous, areolar, and intermuscular connective tissue ; next most com- 

 monly in tlie brain and eye, and lastly, in tlie substance of tlie lieart 

 and otlier viscera of tlie trunk. Several interesting cases have 

 appeared in our own journals. Thus Mr. Toynbee records a case of 

 an hydatid (wbicli I take to be the Gi/sticercus cellulosce) situated in 

 the middle cerebral fossa beneath the dura mater, but in this instance 

 death ensued from other causes. Mr. Ottley gives the case of a 

 woman aged forty, where an undoubted Cysticercus in the brain 

 gave rise to distressing fits, convulsions, and death. Then, again, 

 there is Dr. Burton's workhouse patient, only twenty years of age, 

 who was found dead in bed, and who at the time of admission merely 

 complained of pain in the head. After death, four hydatids {Gys- 

 ticerci) were found in the tuber ancillare at the summit of the spinal 

 marrow. M. Bouvier's similar case is also reported in our perio- 

 dicals. Of instances, also, where Oysticerci occupied the cavity of 

 the eye, we have one or two cases by Mackenzie of Glasgow, one 

 by Mr. Rose of Swaflfham, and others by Windsor, Logan, and 

 Estlin. Amongst the more peculiar cases, I may mention that 

 described by Dr. Greenhalgh in the "Lancet" (1848), where the 

 Cysticercus was lodged within the substance of the lip. Five 

 similar cases are likewise recorded by Heller of Stuttgard. Then 

 there is Dupuytren's case of a Cysticercus ensconced within the 

 great peroneus muscle ; and also Fournier's, where several of these 

 scolices were said to have been found in a boil. Lastly, I may 

 observe that the well-known example of the so-called Trachelocam- 

 pylus, discovered by Fredault in the human brain, is neither more 

 nor less than the common Cysticercus cellulosce. 



It is worthy of remark, as G-riesinger has also observed, that in 

 cases where the Cysticerci have taken up their temporary residence 

 in the brain, they are usually found, post-mortem, in the grey cor- 

 tical or peripheral substance of the cerebrum. The record of an 

 (hitherto incompletely described) instance of this kind, for the par- 

 ticulars of which I am indebted to my colleague, Mr. Hulke, will 

 faithfully illustrate the pathological appearances ordinarily exhibited
