In this group the animals, therefore, in addition to the rice and 

 maize and tainted meat, received fresh vegetables daily, and may be 

 considered to have been well fed. Five monkeys only were used, and, 

 in spite of the extra food, they all lost weight. In fact, Nos. 15 and 

 17 lost no less than 900 and 975 grammes of weight in 180 and 

 31 days respectively. The others, however, did not lose so much 

 weight. In three of the monkeys, Nos. 14, 16, and 17, diarrhoea com- 

 menced from eight to sixteen days after the monkeys had been on this 

 diet. But in Ko. 15 diarrhcea did not commence until the 150th day 

 of observation, and in No. 21 not until the 90th day. In four of the 

 cases blood and mucus appeared in the motions in from eight to 

 eighteen days. AATien it first occurred in No. 21 was unfortunately not 

 noticed. The other monkey, Xo. 15, did not show any signs of it. In 

 two of the monkeys, Nos. 16 and 17, spongy gums occurred; in the 

 former, on the eleventh day, while in the latter it was only noted at 

 the autopsy. The other three monkeys showed no signs of bleeding 

 gums. 



The autopsy of those monkeys which showed scurvy exhibited, as 

 in those of the second group, marked congestion of the large intestine, 

 with bloody mucus in the contents. 



In all the cases there was marked emaciation but no haemorrhage, 

 either into the pleura, pericardium, or peritoneum. 



After this general description of the results obtained in the three 

 groups of experiments, and before discussing their significance, we can 

 consider the changes produced in the blood of animals suffering from 

 the results of scurvy — scurvy being defined by Bristow as " a peculiar 

 form of anaemia arising from a deficiency of vegetable diet, and 

 attended with a tendency to the occurrence of haemorrhages, profound 

 impairment of nutrition, and great mental and bodily prostration." 

 * Only noted at the autopsy.
