them to tlie Yarra. But the main pipes are not yet laid, 

 except for a very short distance ; and, therefore, I do not see 

 that it is too late to lay them in another direction, where we 

 shall find at all times the purest water in the most unlimited 

 abundance. 



But, while I am of opinion that the pipes ought not to be 

 laid, I am most anxious that the capabiHties of the reservoir 

 should be tested before finally abandoning it ; and, for this 

 purpose, I hope that the aqueduct will be completed in time to 

 take advantage of the winter rains. 



I may also notice that no steps have yet been taken to 

 convey the two branches of the river through the swamps. 

 This will cost a very large sum, and of course is not yet 

 contracted for. 



It is deeply to be regretted that a work of such magnitude and 

 importance as that which forms the subject of this paper should 

 be found to be based on incorrect scientific principles ; and it 

 shows the vast importance of cultivating the sciences, even in 

 this remote corner of the globe. 



Had there been a scientific society in this city two years 

 ago, the Commissioners might have obtained more correct 

 information respecting the rate of evaporation in this colony, 

 and more certain and reliable data with respect to the water- 

 shed of the Plenty basin ; which were so necessary to ensure 

 the success of their scheme. 



It was purely on scientific grounds that I was Induced to 

 undertake the investigation of this subject ; and it was the 

 conviction of its great importance, in a scientific as well as in 

 a sanitary point of view, that has led me to submit to you the 

 result of my inquiries. 



If there is any probability of the Yan Yean Reservoir 

 scheme failing for want of water, the sooner this unfortunate 

 result is discovered the better. 



It would surely add Httle to the scientific reputation of 

 Victoria, that a work of such magnitude should be allowed to 

 be completed, at a ruinous sacrifice of public money, before 

 its failure is even suspected.

Mt attention during a part of the last four months having 

 been directed to the meteorology of this place, I propose to 

 lay before this Society the result of the observations I have
