ON THE BRADFORD WATERWORKS. 451 



of evidence that auch vegetables are perfectly suited for the food of man and 

 beast, and that the milk given by cows fed on sewaged grass is perfectly 

 wholesome. To give a i-ecent example, Mr. Dyke, Medical Officer of Health 

 of Merthyr Tydfil, states that since the abundant supply of milk from the 

 cows fed on irrigated grass the children's mortality has decreased from 48, 

 50, and 52 per cent, of the total deaths to only 39 per cent., and that, so far 

 from diarrhoea having been made more prevalent by the use of sewaged cab- 

 bages, " last year the Eegistrar-General called attention to the fact that 

 diarrhoea was less prevalent in Merthyr than in any place in England and 

 Wales ;" and he expressed hisbeKef in " the perfect salubrity of the vegetable 

 food so grown." 



With regard to the assumption which has been made that entozoic diseases 

 would be propagated by irrigation, all the evidence that the Committee has 

 been able to collect, and more especially the positive facts obtained by expe- 

 riments, are against such an idea ; and the Committee is of opinion that such 

 diseases will certainly not be more readily propagated by sewage-irrigation 

 than by the use of human refuse as manure in any other way, and probably 

 less if the precaution be taken of not allowing the animals to graze, but always 

 having the grass cut and carried to them. 



Report of the Committee for superintending the Monthly Reports of the 

 Progress of Chemistry, consisting of Professor A. W. Williamson, 

 F.R.S., Professor Frankland, F.R.S., and Professor Roscoe, 

 F.R.S. 



The Committee have much pleasure in reporting that, during this third 

 year of their publication, the monthly reports of the progress of chemistry 

 have given satisfactory evidence of increasing usefulness. Not only has 

 their circulation in tHs country and abroad increased, but there is every 

 reason to believe that they supply an important want to the progress of 

 chemistry in this country, and will conduce to the advancement of the 

 science. 



The thanks of the Association and of science generally are due to the 

 gentlemen upon whom devolves the labour of making these abstracts, and of 

 thus bringing to a focus the rays of light which emanate from the various 

 places where chemistry is cultivated. 



On the Bradford Waterworks. By Charles Gott, M.Inst.C.E. 



[A communication ordered by the General Committee to be printed in extenso.'] 



In 1854 the " Bradford Corporation Waterworks Act " was passed. Under 

 the power of this Act the Corporation purchased all the existing works, and 

 were charged with the duty of providing the supply of water for the borough 

 and surrounding districts. 



At this time the old works supplied about half a million gallons of waterper 

 diem, a quantity altogether inadequate for the necessities of the inhabitants.
