DEATHS IN THE SOCIETY'S GARDENS. 83 



11. There has been relatively a slight general increase in these 

 diseases of the respiratory organs. They are, of course, largely 

 dependent upon weather. 



12. Thei'e has been a slight decrease in the inflammatory affec- 

 tions of the alimentary tract. In 3 of the mammals and 50 of 

 the birds it was hasmorrhagic, and in 1 of the reptiles it was 

 caused by worms. The remainder of the cases were apparently 

 due to the quantity or quality of the food not being suitable to 

 the aiiimal. 



■ 13. There has been relatively a considerable decrease in the 

 number of cases of nephritis in the mammals and birds. 24 of 

 the cases in mammals and 7 of those in birds were acute. The 

 remainder were chronic cases, of varying degrees, a number of 

 which were associated with other old-age changes. About 100 

 of the deaths have been due to old age, or to the artificial old age 

 induced by captivity. 



14. In a Kiang which died after delivery : the wall of the 

 uterus measured only one-sixteenth of an inch in thickness. 



15. One of these cases was in a Wolf whose son died of the 

 same disease, in the same position, in Julj' 1914. 



16. Two of these cases were in Deer, one in the nose and the 

 other in the liver and intestine ; the third was a lymphosarcoma 

 of the mediastinal glands in a Hamster. 



17. Under the tex-m malaria are grouped 1 case due to Plas- 

 modiu'in kochi, 7 cases due to Hceino2)roteus danileiDsk?/i, and 1 due 

 to Plasmodium prcecox : see also section on blood-parasites below. 



18. 19, 21. See sections on blood-parasites below. 



20. The blood of 3 Viperine Snakes contained a number of 

 large amoebfe, probably from the intestine ; they were also found 

 in numbers in the liver of a Mocassin Snake (comparable with 

 the flagellated organisms found in the blood of reptiles and 

 described in my Reports of 1912 and 1913, and in a paj^er on 

 Blood-parasites found in the Gardens during the years 1908- 

 1911: luVZdP. Z. S. 1912, pp. 235, 406; 1913, p. 141 ; and 1914, 

 p. 181). 



23. Of the aorta in a Seal and a Coati. 



23. The large number of cases of fatty degeneration and 

 infiltration of the liver is probably due to too rich food and 

 insufficient exercise. The greater number of the birds are the 

 small, highly coloured birds from the Small Bird-house, whose 

 food-capacity is enormous. 



24. By far the greater number of cases of gastric ulceration 

 occur in the Primates, generally in connection with diseases of 

 the kidneys or lungs. 



25. In an Ibex with very considerable fsecal accumulation and 

 symptoms of autointoxication. 



26. Both kidneys of a Wallaby were filled with small stones : 

 none in the bladder. 



27. This was a small sarcomatous growth in the kidnev of a 

 Coypu Rat, probably arising from an adrenal inclusion.
