 an aneurysm of the aorta into the thoracic cavity.^ In the 

 Proceedings (1834, p. 9) is a note by Mr. W. C. L. Martin 

 on an aortic aneurysm in a brown coati ; and at the scientific 

 meeting of January 19, 1904, others, from the collection of 

 the Royal College of Surgeons, were exhibited by Mr. Macleod 

 Yearsley. 



Owing to more favourable weather the breeding season of 

 1904 was better than that of 1903 ; but the Council expressed 

 the hope that part of the results might " be attributed to im- 

 proved conditions and management." Two lion and three 

 leopard cubs were born; the first-named were imperfectly 

 formed and died soon after birth ; the latter were eaten by 

 the dam. Eight timber wolves were born in 1903, but all 

 died; a similar litter was thrown in 1904, and of these four 

 were left with the mother, and the other four, which proved to 

 be the stronger animals, were reared by a collie. In all, five 

 attained maturity. The Duke of Bedford's, Altai, and Japanese 

 deer bred, and a hybrid was produced between the last-named 

 species {$) and a Formosan deer ( $ ). The . breeding of the 

 screamers has been mentioned; three chicks were hatched, 

 and two lived for some months. Three cases of hybridity in 

 doves are worth record,t and there were a good number of 

 pheasants reared. 



The value of the birds reared in 1904 was £173 10s., which 

 is in striking contrast with the return (£8 5s.) for 1903. There 

 Avould seem to be no reason why surplus stock, as a result 

 of breeding, should not be an important source of revenue, 

 as it is, for instance, at the Antwerp Garden. 



Besides the two gorillas, the Society lost this year an 

 orang and a chimpanzee. A Grant's zebra, and the Grevy's 

 zebra ( $ ) presented by Sir John Harrington, were also among 

 the losses ; the latter was said by some to have died from in- 

 juries received during breaking and training. Of this there 

 is no evidence. It is to be regretted that so valuable an 

 animal was made the subject of experiment — at any rate, till 

 Milne, who had been successful with a young mare, had tried
