large fractions, to which the druggists' weights and measures are 

 not adapted. But to guide the intelligent apiarist, I will explain 

 the weights and measures as above used, as far as possible. Solu- 

 tion 1 is prepared bv weight, of whioii it takes one part of the acid 

 to ten of alcohol of the proper strength. Solutions No. 2, 3,, 4, 5 

 and 6 are to be prepared by measure. CC means cubic centimeter. 

 One thousand of these is called a "liter," and the weight of a liter 

 of wafer, at its greatest density, is called a kilogramme, and the 

 weight of one CO, or cubic centimeter, ol water at its greatest den- 

 sity, is called one gramme, being the unit of weight. 



10 grammes - 154.3403 Troy grains. 



100 grammes , 1543.4023 Troy grains. 



10 00 or cubic centimeters 3. 7053 fluid drachms. 



100 00 or cubic centimeters " " ' 1.5675 pints, apothecary's measure. 

 It thus appears that if exactness is required, a reduction is not 

 advisable, and only Solution No. 1 may be prepared by using any 

 weight in the proportion of one to ten. Hence, to bo sure, two 

 French graduates should be obtained — one to measure up to 100 

 CO and the other up to 500 00. A thermometer is also necessary, 

 to observe strictly the temperature as given above, as also an atom- 

 izer for spraying. Care must be taken not to mistake the different 

 solutions, but each one kept in a labeled bottle, well corked. The 

 silutions should be well heated before using, and cooled down to 

 the proper degree of temperature before applied. For the conven- 

 ience of bee-keepei's, I have put up such sets of apparatus, which 

 I shall, with a bottle of Solution 'No. 1, send by express on receipt 

 of $5.00., Orders filled in rotation. Persons ordering sucL must 

 allow from two tj three weeks in filling them.
