valescence and regeneration of patients and, that in 1946 or shortly thereafter, recently devised forms of treatment rendered the estab- lishment of such a settlement unnecessary. Evidence was given which indicated that new forms of treatment did tend to render obsolescent, in some cases at least, forms of after-treatment which, previously, had been more or less common and which could be effective only if administered over a long period of time. On this basis it was said that it became unnecessary for the hospital's purposes to occupy or use the whole of the land and that its continued retention of the land in question in no way served any such purpose.
Three observations should be made at once concerning these submissions. First of all, it may be said that, although the evidence is scanty it sufficiently appears that the project envisaged in 1944 and which, about that time, the respondent commenced to carry out involved a single, though comprehensive, purpose. But though it was a long term project capable of development only over a number of years it could in no sense be said that it comprised a series of projects to be carried out on several parcels of land. Secondly, although the contrary assertion was made in argument, the evidence does not show that the land in question was acquired or held for the establishment of a village settlement or that it was held, merely, to fulfil a future purpose which it was, for a time, contemplated that the land might serve. It may be that, originally, it was thought that some part of the land might be put to such a use but, even if this were so, I can find nothing to suggest that it was a material factor in determining the area which Dr. McCaffrey and Dr. Hughes appear to have thought desirable or necessary for the establishment of a sanatorium and hospital. Finally, it may be said that it is of little assistance to the appellant to assert that the acquisition of the whole of the area by the respondent was, in point of fact, unnecessary to permit the effective establishment of a sanatorium and hospital if, upon the facts, it may be said that it has been used for the purposes of the respondent as a public hospital. If, within the meaning of S. 132 (1) (d), it was SO used it is nothing to the point that newly developed forms of treatment made it unnecessary in the opinion of some people for a tuberculosis sanatorium to be estab- lished in open country or that, in the present case, the appropriation of a substantial area of bushland did not, in fact, result in any benefit or advantage in the treatment by the hospital of its patients.
A medical practitioner called as a witness by the appellant testified that a sanatorium of this type does not require any greater area of land than a general hospital. This, however, was not the effect of medical evidence called on behalf of the respondent. But what is more to the point, the effect of the evidence of Dr. McCaffrey
