TABLE 4. Rate of destruction of invertase in 50 per cent alcohol containing 6 per cent 



of cane sugar. 



This rate of destruction is far less than that shown for 50 per cent 

 alcohol in Table 3, namely, 0.850. The cause of this difference can 

 lie only in the fact that cane sugar was not present in the latter

experiments. Several other experiments have given results agreeing 

 with these in showing that cane sugar exerts a very strong influence 

 in protecting invertase from destruction by alcohol. O' Sullivan
