and a Baboon were both pet animals, but neither of them was 

 allowed oiit of quarantine, which is the best way of keeping fresh 

 infections out of the Gardens. The birds show a remarkable 

 reduction of deaths from tubercle of neai'ly 50 per cent. ; and, if 

 the overcrowding of many of the bird-houses could be done away 

 with, there does not seem any reason why there should not be a 

 still further improvement. The greater number of the cases 

 have been amongst the Gallinaceous birds, but this year a 

 Flamingo succumbed to tubercle, for the first time since records 

 have been kept. In only 19 of the birds were the lesions gene- 

 ralized, which is a much smaller percentage than usual, and 

 indicates a less severe type of the disease. The 2 cases in the 

 Reptile-houses make the smallest number since records were 

 kept : there seems no reason why it should not be completely 

 driven out. One of these cases was in a Crocodile, in which it 

 was general ; this is the first recorded case in this particular 

 aninaal. 



3. All the mould diseases are grouped under Mycosis. 6 of 

 the mammals were Kangaroos and the disease was of the ordinary 

 type ; it occurred in a Deer and a Squirrel, for the first time, 

 forming tumours in both — the moulds in each of these two cases 

 were of a species new to the Gardens. There is a very great 

 reduction in the number of cases occurring in birds, of considerably 

 over 50 per cent. A Duck 14 days old was filled with growth 

 of the organism, and, in a Pheasant, mycetomata (mycotic 

 tumours) occurred in the lungs, which is very unusual in birds. 

 Amongst the reptiles a Ceratophrys and an Anaconda died from 

 mycetomata, and a Ceratodus, which had been many years in the 

 Gardens, died from a mould disease of the skin, similar to that 

 from which several of the larger toads and frogs have died. 



4. There is a more than relatiA^e decrease in the number of 

 cases of pneumonia, especially among the birds and reptiles. In 

 the mammals it seems to be particularly associated with pyorrhoea 

 and rickets. In two of the reptiles it was due to worm eggs and 

 embryos, in the rest it was pneumococcal. 



6. The septicsemias were due to dii'ty wounds in 3 cases, to 

 pneumococci in 2 cases, and to an abscess in the antrum in 

 1 case. 



6. Due to worm-cysts in a Squirrel, and in both of the birds 

 due to injury, from, in the one case a nail, and in the other a 

 thorn. 



7. This occurred in a Deer, associated with putrid bronchitis, 

 and was of the sacculated variety. It is the only case I have 

 seen in an animal. 



8. This was an acute hfemorrhagic cystitis in a Wolf, due to 

 infection with Bacillus colt. 



9. In a Cobra in which over 60 per cent, of the erythrocytes 

 were infected. 



10. Due to a rare parasite whose position is still uncertain, 

 and found here in a reptile for the first time.
