590 PROCEEDIKGS OF SECTION G". 



The testicle measured 5 by 10 in., and weighed 5 lb. It was- 

 nodular, and,;when cut into, was found to contain a cavity, the con- 

 tents of whic;I> were breaking down. 



The nodular growth in the pelvis was very irregular in shape, 

 and it invoilved the genito-urinary organs. This part of the specimen 

 was fou,nd to be secondary to the disease of the testicle. 



liie following is a naked-eye description of the specimens : — The 

 testicle was very nodular, and about three times the normal weight;, 

 the tunics were adherent, and enormously thickened ; the blood 

 vessels were much distended, and in the posterior extremity a cavity 

 was found, 2 in. in diameter, with very irregular walls, containing a 

 quantity of dark, semi-fluid, broken-down tissue. The growth from 

 the pelvis was firm in consistency, and very nodular, the nodules vary- 

 ing in size from a marble to two clinched fists. When these nodules 

 were cut into they were found to consist of a dense capsule, surround- 

 ing a firm and glistening structure, which contained paths of what' 

 appeared to the naked eye as connective tissue. 



Sections were prepared for miscroscopical examination, and the 

 following found : — Small sarcoma-like cells ; epithelioid cells,. 

 resembling cells found in myeloid sarcoma ; sarcomatous cells, form- 

 ing the Ijulk of the tumour at this ])art ; fil.>ro-cellular trabeculse, with 

 round-celled infiltration. 



An artery cut longitudinally showed proliferation of its endo- 

 thelium, and epithelioid and sarcomatous cells in a space in the- 

 muscular coat of the wall of the artery ; and sarcomatous cells occupy- 

 ing lymph spaces in the false capsule of the tumour. ^ 



Lymph spaces lined with endothelial cells were found in many 

 parts of the capsule, and this gave the key to its pathological posi- 

 tion among tumoursi — endotheliomata. 



This is the fii'st time this class of tumours has been found in 

 animals. Dr. J. M. Cai-ter, Y.M.l)., says, in his able article on tumours, 

 in the ■Veterinary Archives," Vol. XXII., 1901, page 700: '-Endo- 

 thelioma, a tumour of purely endothelial origin, is found only on 

 serous membrane. It closely resembles cancer. Has never been 

 seen in domesticated animals.'' 



3.— SMUT EXPERIMENTS IN VICTORIA DURING 1908. 

 By D. McALPINE. Geol. VegetnhU Patholoc/ist of Victoria. 



Although there are over 60 species of smuts (Ustilaginece)' 

 recorded for Australia, there are only a comyiarative few which attack 

 our cereal crops, and these have necessarily received the most atten- 

 tion on account of their economic importance. 



Among these the parasitic smuts occuring on wheat have been 

 princip.illy attended to. and I jiroposo dealing with two of the most 

 import, jit — viz. : Stinking Smut oi- Bunt and Flag Smut. 



The exjieriiiieiits in conntctiun witii stinking smut are chiefly 

 concerned with the supposed discovery of a resistant wheat, and the 

 means whereby an immune variety is liktOy to lie secured. In the 

 case of flag smut, the experiments refer to its mode of germination and' 

 infection, with a view to its ultimate prevention.
