In carrying out the tests previously described only a ver}^ small 
outlay in apparatus will be required. The special spindles for de- 
termining the water content of honey and the other apparatus can 
be obtained from any manufacturer of chemical goods. Glass or 
metal cylinders for containing the honey while spindling will be 
needed, as also a collection of test tubes and racks. A small 50 cubic 
centimeter graduated cylinder will also be found useful for measur- 
ing out the volume of honey solutions and of reagents. All appa- 
ratus should be thoroughly cleaned and rinsed after using, as any 
contamination with impurities may affect the accuracy of the tests. 
The drugs specified may be purchased of any druggist.
