DISCUSSION OF ANALYSES. 81 



BEERY HILL DYSPEPSIA WATER (No. 1024 I. & W.). 



The advertised and the Bureau of Chemistry analyses of this water 

 agree with each other quite closely in most cases. The owners, how- 

 ever, claim 8.9 parts per million of hypophosphorous acid ions, while 

 the authors were not able to find, and in fact hardly expected to find, 

 any of this acid. 



GITCHE CRYSTAL SPRING WATER (No. 1025 I. & W.). 



The authors were unable to obtain the advertised mineral analysis of 

 this spring. The sanitary analysis, although differing from that adver- 

 tised, as would be expected, was satisfactory. 



GREAT BEAR WATER (No. 1026 I. & W.). 



The advertised and Bureau of Chemistry analyses agree very satis- 

 factorily with one another except for chlorin, and even this difference 

 is of no importance and is explained satisfactorily by the owner's 

 letter, which follows: 



Regarding the amount of chlorin which your analysis of our water shows, we are 

 advised by competent authority that even if correct it would not under our condi- 

 tions indicate contamination, as our springs are remote from any habitation. They 

 are, however, but 20 miles from the salt deposits of Syracuse, and wells bored to any 

 considerable depth in the vicinity of our springs produce salt water. 



It is only fair to the owners of this spring to say that although the 

 first sample of Great Bear purchased by us undoubtedly contained 21.5 

 parts of chlorin per million, subsequent samples were examined which 

 contained approximately the amount of chlorin given in the advertised 

 analysis. It is also probable that the first sample was entirely genuine 

 and that the variation in the amount of chlorin was caused by the salt 

 deposits as suggested. 



LONDONDERRY LITHIA WATER (No. 1116 I. & W.). 



The difference between the advertised and "the Bureau of Chemistry 

 anatyses of this water is remarkable. Not only are the analyses 

 different to a marked extent in nearly every item, but particularly is 

 this noticeable in the case of lithium, the advertised analysis giving 

 10.3 parts per million while the Bureau of Chemistry examination 

 shows only a spectroscopic trace. It is needless to say that it is a 

 misnomer to call the water purchased by us under the name of " Lon- 

 donderry lithia water" a lithia water. 



WHITE ROCK LITHIA WATER (No. 1117 I. & W.). 



While there is some variation between the advertised and Bureau of 

 Chemistry analyses of this water it is not significant except in the case 

 of lithium. For this element the advertised analysis claims 38.1 parts
