to Mr. BowJby. The bladder was contracted and thickened The 
mucous coat was covered with a shreddy mass of finely fiSrillated 
villous growth. The ureters were dilated, with thickened walls, and 
the mucous membrane was covered by a phosphatic deposit. The 
kidneys were in a state of suppuration. Under the microscope the 
thickening of the bladder wall was found to be due to an interstitial 
overgrowth of fibrous tissue, and the mucous membrane had been 
destroyed and was replaced by young fibrous tissue. There were 
numerous ova imbedded in the wall -of the bladder. The walls of the 
ureters were filled with ova, some of which could be seen in the 
mucous membrane where it had not been destroyed The kidneys 
showed the changes due to nephritis, and contained numerous ova. 
The lungs were semi-solid ; several ova scattered through them. 
The second patient was a boy, seventeen years of age, from whose 
rectum Dr. Mackie removed a tumour (exhibited). The patient had 
suffered from rectal pain and the passage of blood. The tumour 
consisted of a diffuse papillomatous growth, which under the 
microscope was found to consist of a loose, richly cellular, fibrous 
tissue, in the interstices of which were numerous ova. 
Dr. Stephen Mackenzie said the opportunity of studying the 
general pathology of this disease was rare. He asked what was the 
gm o the coagula and fibrous threads often seen in the urine in 
these cases. Were 
any parent worms found in the bladder? They 
nearly always inhabited the blood-vessels. The ova in the alimentary 
canal were said to have lateral spines, while those in the urinaiy tract
