weeks. If all those iuterested in tlie slaugliter of sheep, oxen, 

 pigs, and other animals, ^Yhenever they saw an}' indication of 

 hydatids in their internal organs, cut out the affected parts and 

 burned them the disease would be stamped out within four 

 months. Of course there would be still those animals affected 

 with the diseases ; but as far as human beings were concerned, 

 the doctors would cure some, the hydatids would kill some, and 

 others again would outlive the hydatids. There was a want of 

 knowledge how to deal with this matter all over the colony ; 

 the people were looking everywhere for means to escape from 

 or cope with this disease, but they had looked in the wrong 

 directions. 



Dr. Thomas, in reply to the criticisms and observations made 

 on his papers, referred briefl}' to the various points involved in 

 the discussion of such a subject, and expressed the opinion 

 that Professor Tate had pointed out the direction in which 

 inquiries should be made. While his statistics were not so 

 complete as was desirable, he believed they were as complete 

 as could be obtained in the colonies. He believed that the 

 tapeworm and Tsenia were conveyed into the dog by means 

 of herbivorous animals, and that at least -AO per cent, of 

 the stray dogs of the city were affected with this pest. In 

 fact, the specimens of the Taenia which had been shown 

 "under the microscope had been taken from various dogs of 

 that description. He suggested that pigs or other suitable 

 animals should be obtained and inoculated, and kept for say 

 twelve months, as by this means all the stages of the parasite 

 from the larv^ to the secondary cysts might be ascertained. 

 Even if his comparison had been restricted to a seven years' 

 experience of the Adelaide and Mount G-ambier Hospitals, 

 he did not think that it would alter the fact that the ^outh- 

 East was the worst place after Iceland for hydatids. In 

 referring to the four factors which, in his opinion, regulated 

 the spread of hydatids, he never meant to say that the number 

 of herbivorous animals or dogs decided this question, but that 

 these factors must all work together iu a co-ordinate strain. 

 "With regard to water being the main medium for the propaga- 

 tion of the disease, Dr. Jackson was distinctly of opinion, 

 before the people of the South-East awoke to the fact, that 

 their water was their poison, that they were very careless in 

 their use of it. He intended to have the water of the district 

 tested, not only shortly, but also later on in the season. He 

 also intended, if possible, to ascertain what proportion of the 

 sheep and cattle had the hydatid disease. Mr. Chalwin, the 

 veterinary surgeon, had made the statement on good authority 

 that e^^ery beast was affected, and as he thought the kangaroos 

 also were very much affected with hydatids of the liver, of
