NOTICES OF IRISH ENTOZOA. 



The smallest vesicular tumors were spherical, but the 

 larger were all depressed or lenticular, with a round or ellip- 

 tical outline [Fig. 32, a). On examining these tumors, I had 

 first to remove the peritoneal covering, under which was a 

 white, thickish coat, of so soft a consistence that it could not 

 be torn off like a membrane, but yielded to the forceps. — 

 When this coat was perforated, a white, curdy fluid could be 

 pressed out in considerable quantity, and along with it the 

 Entozoon itself, (or sometimes two from the same capsule), of 

 very small size, the animal bearing no correspondence in its 

 bulk to that of the entire tumor.

On getting the animal freed from its habitation, and wash- 

 ing off all extraneous matter, it appeared of an ovate form, 

 and was very sluggish, though exhibiting signs of vitality by 

 soon losing its regular outline, and contracting its margin so 

 as to form various scallops and indentations ; and after long 

 watching it in the microscope no farther change could be ob- 

 served. 



I then tried the effect of compression : a specimen was laid
