as deeply as the serous coat, tlie others were less deep and 

 involved only the mucosa and a part of the muscular walls of the gut. 

 The Marsupials with gastric ulcer were all herbivorous. 



Perforation of the Uterus. — An instance of this unusual accident 

 occurred in a bitch of the jSTorth- African Jackal {fJanis anthus). 

 The mammary glands betokened recent activity, and on opening 

 the abdomen the uterus projected well above the joelvis ; there was 

 general peritonitis and the uterus itself was dark and intensely 

 congested. Within it lay a dead and extremely offensive foetus, 

 while a small circular perforation existed in the uterine wall just 

 above the cervix on the left side, and it was appai-ently due to 

 leakage through this hole that peritonitis had set in. 



Neio Growths. — The rarity of new growths referred to in last 

 year's note is confirmed by this year's post-mortem examinations 

 on a larger number of animals. Only four cases occurred ; two of 

 these, both in mammals, were carcinomata and presented no 

 unusual features ; but the third case, a Bear, had multiple small 

 angeiomata of the liver, none bigger than a sixpenny-bit, which 

 cannot have exerted any evil effect on the health of the animal. 



The last case occurred in a Chilian Pintail {Dafila spinicauda) 

 alleged to have been bred in the menagerie and to be 26 years old. 

 On opening the bird a mass the size of a turkey's egg was seen 

 occupying the right flank, in the front of the belly ; it was not 

 adherent to the intestine or other organs but was enclosed within 

 a thin, loose capsule resembling peritonexim within which, with 

 the mass, were the supra- renals, which were not affected. The 

 mass could not be traced to any organ, but seemed to arise at the root 

 of the mesentery ; no testes could be found, although the trachea 

 was of the normal male type ; there was a white mass about the 

 size of a filbert in the right lobe of the liver, and both kidneys 

 were whitish and much enlarged. Microscopically it was seen that 

 the main mass was structurally a carcinoma, as was that in the liver, 

 and both these masses resembled the much enlai-ged kidneys which 

 were themselves carcinomatous. 



My thanks are due to Mr. S. G. Shattock for the diagnosis 

 of this remarkable case, which it seems must be classed as an 

 example of diffuse carcinomatous growth in both kidneys with 

 secondary masses in the liver and glands at the root of the 

 mesentery. 



While considering the occurrence of new growths in bii-ds 

 allusion may be made to two very interesting conditions which 

 liave recently come under my notice. The subject of the first of 

 these was a domestic fowl belonging to Dr. R. N. Salaman * 

 which died suddenly. On opening the belly cavity this was found 

 to be full of blood, and the liver was found to be diffusely angeio- 

 matous. The second condition occurred in a tSparrow examined by 

 Dr. A. Wilson * in the course of certain physiological work. On 

 opening the skull a spherical mass about the size of a pea was seen 



* My thanks are due also to these gentlemen for allowing me to refer to their 

 specimens.
