FRENCH FLUID MEASURES. 



The cubic centimetre, usually represented by "c.c." is the 

 unit of the French measurement for liquids. It contains nearly 

 seventeen minims of water; in reality, it contains 16-896 

 minims. The weight of this quantity of water is one gramme. 



Hence it will be seen that the cubic centimetre and the 

 gramme bear to each other the same relation as our drachm 

 for solids and the drachm for fluids, or as the minim and the 

 grain. The following table will prove to be sufficiently 

 accurate for microscopical purposes :
