of 30 5'ears, viz., 1852 to 1882. During this time 158 cases of 

 hydatids were recognised and treated. There were in all under 

 treatment as in-patients 3(3,550 persons, so that about one case 

 of every 245 — exactly 2-14'68— in-patients was hydatids. As 

 regards the results of the treatment, we find that in 13 cases 

 the results were not given : of the remaining 145, 20 died 

 whilst in hospital, being at the rate of 12"GG per ceut. 



The Mount Gamhier Hospital. — I have to thank Dr. Jackson, 

 lately Assistant Colonial Surgeon, for the statistics of this 

 hospital during the seven years 1873 to 1880, and they are very 

 significant. During these seven years 36 cases of hydatid 

 disease were under treatment. During the same period there 

 were of in-patients 1,905. So that no less than one case out of 

 every 52 "9 was hydatid disease. I am convinced that out of 

 Iceland no place in the known world is so badly infested with 

 this parasite as the South-Eastern district of this colony, whicb 

 supplies the majority of the inmates of the Mount Gambier 

 hospital. As 1 shall revert to this point afterwards, I need 

 not discuss it here. In order to strike an average for the 

 hospitals of South Australia we must add together the results 

 of the Adelaide and Mount Gambier Hospitals. This will 

 show us that about one case out of 198 in-patients suffered 

 from hydatids. 



QuEENSLAi^^D. — According to Hayter, the populatian of 

 Queensland on ])ecember 31st, 1880, was 226,077 persons. 

 The average death-rate for the decade 1869-79 was 17"27 per 

 1,000. It appears that the published statistics of this colony 

 did not contain any particulars respecting deaths from hydatid 

 disease prior to the year 1878, so that the only data at my 

 disposal have extended over the four years 1878 to 1882, and 

 during this time only five deaths from this cause were 

 registered ; so that only about one death out of 6,000 arose 

 from hydatid disease in Queensland. 



The Hospital Statistics of Queensland. — Eeturns were sent 

 from the hospitals at Bowen, Ipswich, Springsure, Stanthorpe-, 

 Charters Towers, Towoomba, George Town, and Maryborough. 

 In five of these no cases of hydatids had been met with, viz., 

 Bowen, Charters Towers, George Town, INIaryborough, and 

 Springsure. As regards the Ipswich Hospital, the return com- 

 prises the 20 years 1860 to 1880. During this long period only 

 two cases of hydatid disease were treated. The average number 

 of in-patients is stated to be 300 per annum. The Stanthorpe 

 Hospital's record extends over the five years 1875 to 1880. 

 Eour cases only were observed, and one of these was not a 

 hospital case. In the Toowoomba Hospital books only one 

 case of hydatids appears. Thus it will be seen that the data
