solids is 7.56, and the i>erceiitage of reducing sugar before inversion to 

 total solids SC.77; tlie means of sucrose as determined by both methods 

 are low aud fairly agree, although as in the other tables they differ 

 widely in single instances. 



Tai)h No. V. — These honeys, obtained directly or indirectly from well- 

 kiiovrii apiarists, I have every reason to believe to be pure. If they 

 contain any adulteration it has been added by artificial feeding and not 

 intentionally. It will be observed that these honeys are strongly Lnevo- 

 rotatorv, and indeed so much so that some of them might have appeared 

 in Table Xo. III. 



It will be instructive to compare the numbers in the above tables with 

 those obtained by other analysts. Koenig* gives the following mean 

 of seventeen analyses : 



O. Hehner t gives the following numbers as the mean of twenty-five 

 samples: 



According to Hehner, the fluidity of the honey does not depend on 

 the amount of honey it contains. In ten cases the quantity of glucose 

 after inversion was less than before, in one instance 5.23 per cent. less. 

 The rotating power was generally zero, a condition which I have never 

 found in American honeys, genuine or artificial. These conclusions are 

 so at variance with ordinary experience as to indicate that the samples 

 analyzed were anomalous or the methods employed unreliable. 



Siebcnl gives the mean comx)osition of sixty samples of honey as 

 follows : 



The solids not determined, as will be seen by the analyses presented 

 in this report, are of considerable importance. In adulterations with 

 the starch sirup these undetermined solids co-i^i.st chiefly of maltose
