 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.
