use it and supply it to stock-owners for several years, with the 

 result that pleuro-pneumonia was practically stamped out of the 

 herds of Victoria, and the possibility of tuberculosis being spread 

 by means of tainted pleuro virus greatly reduced. 



By obtaining the Veterinary Surgeons Act, and providing for 

 the registration of all qualified veterinary surgeons, stock-owners 

 could protect themselves from the imposition of unqualified prac- 

 titioners, while the establishment of a veterinary college has been 

 the means of saving the lives of thousands of valuable animals 

 and much wealth to the community. 



The introduction of tuberculin testing for tuberculosis in 

 cattle, and its frequent use by members of the profession in 

 detecting the disease in its most latent forms, has led to an 

 enormous reduction in the prevalence of that disease in cattle, 

 and indirectly of that of many human beings. 



Inoculation for the prevention of blackleg in calves has been 

 the means of preventing much loss to dairymen from that disease. 



The general outbreak of swine fever in 1901 was practically 

 stamped out in Victoria in three months, through every qualified 

 veterinary surgeon in the State being appointed an inspector, and 

 acting under my instructions. 



2. ANAPLASMS OE JOLLY BODIES?

CORPUSCULAR BODIES PRESENT IN THE BlOOD OF MaMMALS.

Since Theiler (1) published the results of his research upon cer- 

 tain bodies in the red blood corpuscles of cattle in South Africa, 

 and to which he gave the name of Anaplasm, a great deal of in- 

 terest and some discussion has been aroused as to the significance 

 of morphologically and tinctorially similar bodies sometimes ob- 

 served in the erythrocytes of other species of animals in other parts 

 of tlie world. Already they have been recorded from man in cases 

 of leukaemia, the horse, donkey, sheep, goat, pig, cat, mar- 

 supials, and monotremes, and the Australian dingo (native dog). 

 Tn addition to these, their presence in the blood of lemurs, mouse- 

 deer, orang-utan, and capuchin monkey is detailed in the follow- 

 ing article, with some observations as to their probable origin and 

 significance. 



The interest in what Balfour calls " these enigmatical bodies," 

 is increased owing to the fact that Theiler showed in his experi- 

 ments that the anaplasms of cattle in South Africa have a patho- 

 logical signification, being responsible for certain abnormal condi- 

 tions in their host, and that they could be transmitted from animal 

 to animal both by artificial inoculation, and, naturally, by ticks.
