HEPWORTH, ON COMPOUND NUCLEATED CELLS. 141 



Infusoria, with a preponderance of the characters of the 

 former class. 



I propose the folloM'ing generic characters for the animal : 



CLASSIS ROTIFERA. 



Familia Monocercad^. 



Genus Bysteria (Huxley). 



Lorica bivalvis, inaefquivalvis, fere tola margine liiante. Corporis facies 

 capitales et veutrales ciliatse. Apparatus manducatorius valde elougatus, 

 in niastacc dignoscenda nou iuclusus. Cavitas digestiva amplissima, sim- 

 plex. Pes inarticulatus, indivisus, spathulatus, corapressus. 



Sp. B. armala (Huxley). Species unica. 



On Compound Nucleated Cells. By J. Hepworth, Esq. 



Although many writers speak very positively as to the 

 compound nucleated cell being invariably a characteristic 

 sign of cancer, my observations for some years past have 

 led me to doubt the truth of this. I believe it is more fre- 

 quently found than otherwise ; but not always. 



H. J., a female, aged fifty-five years, applied to me, haAdng 

 an ulcer on the upper lip, which had all the characteristic 

 signs of cancer, except the nucleated cell. I removed a V-shaped 

 portion of the lip, including the disease ; the parts healed, 

 and I heard nothing more of the case until after a lapse of 

 two years, when the woman presented herself again, with a 

 similar ulcer on the nose ; so situated, that the knife could 

 not be used with advantage. It resisted every remedy, and 

 gradually went on, though slowly, to a fatal termination; 

 after destroying the nose, and dipping into the orbit. 



I frequently examined very carefully the secretions from 

 the surface, and from time to time snipped small portions 

 from the parts ; but never detected a nucleated cell ; I only 

 found pus-globules, altered blood-discs, and exudation-cor- 

 puscles. 



L. T., a man, aged forty-five, died of cancer of the stomach ; 

 on examination, the greater and lesser omenta colon, and 

 stomach Avere all shrivelled iip into a hard scirrhous mass, the 

 coats of the stomach were three quarters of an inch thick, 

 the pylorus was ulcerated ; although I had no doubt as to 

 the nature of the case, I detected no nucleated cells.
