about the size of a whippet dog, and superficially resemble deer. 

 Anatomically, however, they are more related to the pig family 

 than to tlie deer. Another point of interest is the minute size of 

 their red corpuscles, their average diameter being about 2.5 

 microns. The above species of Tragu'lidae is very common in Java. 



Early in 1911, three mouse-deer arrived at the Zoological 

 Gardens, Sydney, from Java. Tliey had been captured only a 

 few weeks previously, and apparently were in good health on 

 arrival. One died on 25th October, about two weeks after admis- 

 sion, the apparent illness being of short duration. No gross 

 lesions were seen on post-mortem examination, except t!iat the 

 tissues generally were oedematous. Trypanosomes {Tr. ingens) and 

 micro-filarise were present in the general blood stream, also an 

 occasional piroplasm of the mutans type. In addition to these 

 organisms, there were present fairly abundantly in the erythrocytes 

 very minute spherical dots taking the chromatin stain. Reference 

 to the figures will enable one to appreciate the size of these bodies 

 in Fig. 4, in comparison with those from other animals. There 

 was nothing in their tinctorial characters or morphology, except 

 size, to distinguish them from the chromatin bodies found in the 

 marsupials, lemurs, &c., or the Jolly bodies in rodents, or :^rom 

 the anaplasms. Some showed a distinct marginal disposition. 

 Others occupied various other positions in the red blood cells. 

 There was very little variation in the size of the dots. Those ob- 

 served were all single, no double ones being demonstrated. The 

 bodies were relatively fairly numerous, one or more occurring in 

 every field of the microscope. 



The other two mouse-deer died on 29th October, 1911, and 21st 

 April, 1912, respectively. Micro-filariae and trypanosomes were 

 present in their blood, but the chromatin bodies observed in the 

 red blood 'cells of the first animal were totally absent in the second 

 and third. 



Chromatin Bodies in Lemurs. 

 Case No. 1. — On 1st May, 1912, a ring-tailed lemur {Lemur 

 catta), died unexpectedly at the Zoological Gardens, Sydney. No 

 previous illness had been observed by the keepers. The result 

 of the autopsy was as follows : — The abdominal cavity contained 

 a large quantity of blood. The liver was enlarged and in a state 

 of very advanced fatty degeneration. A ragged rupture ex- 

 tended from the lower border of the left lobe for about an inch 

 into the substance of the organ. The spleen was slightly swollen, 

 and the capsule exhibited a peculiar mottling. It was also 

 softer than normal. The heart was dilated and flabby. The 

 lungs were blanched and the kidneys swollen. Microscopical 

 examination of the blood showed the presence of numerous normo- 

 blasts and polychromatophilia, also numerous spherical bodies in
