its structure to leave no doubt of its identity ; in these 

 [instances] the cysts contained a turbid fluid and a small 

 pellet of albuminous matter, the remains of the worm. 



Several new instances of the occurrence of Cysticercus 

 ceUulosa in the eyeball of man have been published. A 

 former case which was observed by Estlin (Medical Gazette, 

 vol. xxii, p. 839 ; Gaz. Med. de Paris, 1840, p. 776 ; or 

 Rayer, Archives de Med. Comp. 1843, Nr. 2 et 3, p. 125), 

 and which does not appear to have been known in Germany, 

 is the following : " A little girl, of six years of age, was 

 brought to Bristol on account of an affection of the eye. 

 There was, at the internal angle of the right eye, imme- 

 diately above the caruncula lachrymalis, a semi-transparent 

 tumour of the size of a currant. Estlin opened the tumour, 

 on which, besides a viscid puriform fluid, a white hydatid 

 came into view, which under the microscope proved to be a 

 Cysticercus." 



It is related by Cunier (Annales d'Oculistique, torn, vi, 

 1842, p. 271 ; or Rayer, Archives de Med. Comp. 1. c. p. 

 128 ; or Froriep's n, N. Nr. 557, p. 104) that a Moth flew 

 against the right eye of Comte de B., aged 16, so that it 

 was necessary to extract one of the feet of the insect from 

 beneath the eyelids. Five months afterwards an inflam- 

 mation of the eye was set up, in the course of which a small 

 tumour was noticed on the conjunctiva near the cornea. 

 This swelling after some months had become developed into 

 a hydatid tumour. After its removal by Cunier it proved 

 to be dependent upon a Cysticercus celluloses. 



Three instances of this Cyst-worm under the conjunctiva 

 of living man, have been communicated by Sichel. (Journal 

 de Chirurgie, par Malgaigne, 1843, p. 401 ; or Oppenheim's 

 Zeitsch. fiir d. ges. Mediz, Bd. xxviii, p. 570.) In the first 

 case, a girl, seven years old, who had never received a blow 

 or any traumatic injury in the eye or in its neighbourhood, 

 presented, in the external portion of the conjunctiva of the 

 left eye, two lines from the edge of the cornea, a round 

 tumour, which, covered by the reddened conjunctiva, and
