quantity of serosity ; a similar fluid was between the dura 

 mater and the arachnoid membrane, and the same was 

 the case in the larger ventricles of the encephalon. The 

 other viscera did not offer anything remarkable, except 

 the paleness and flacidity of their tissue. The great 

 fatigues of the chase, and the immersion of these animals 

 in water at the time when they were very much heated, 

 appeared, to have been the causes of this singular disease. 

 In the 'Report of the Clinique of the. School of Alfort,' 

 in the year 1825, the same anemia was remarked in two 

 dogs that died there ; one of them had lately undergone 

 a considerable haemorrhage, and in the other anaemia had 

 developed itself spontaneously. 



" It is, in fact, among dogs that this extreme anaemia 

 has been principally observed, and it is ordinarily fatal. 



" This disease, according to M. Vatel, is generally the 

 symptom of a chronic malady, or the instantaneous effect 

 of an excessive haemorrhage. It is rarely primary. The 

 extreme discoloration of the tissues, and of the mucous 

 membrane riiore particularly ; the disappearance of the 

 subcutaneous blood-vessels ; and the great feebleness of 

 the animal, are the princip^il symptoms. There also often 

 exists considerable swelling of the limbs."* 



Treatment. — This, in the iirst instance, should consist 

 in removing the cause ; and, secondly, in assisting nature 

 to restore the deficiency in the colour and quality of the 

 blood by those agents which form the necessary con- 

 stituents of healthy blood. For the former, a nutritious 

 diet, with a free allowance of fresh air, sunlight, and. 

 exercise, should be ordered. Vegetable and mineral tonics 

 especially the preparations of iron,- and, if there be much 

 emaciation, cod-liver oil, should be prescribed for the 

 latter. Salt-water baths are also beneficial.
