The solution P was prepared as follows: 1,5 gr. NHyNO3, 1,5 gr. KH,PO,, 1,5 gr. MgSO,.7H,O and + 0,3 gr. CaCl, were 
dissolved in boiling distilled water; after cooling + 1,85 gr. benzaldehyde was dissolved and the clear solution was filled up with 
H,0 to 1 Liter. 
Solution Q was obtained by dissolving 2,5 gr. amygdalin in distilled water, this solution was boiled during a short time 
and after cooling filled up with H.O to 250 cM3,
