Dear Sirs:
	We are looking for the observed Hammett sigma constants for doubly 
substituted benzenes involving NH2, NO2, CH3, Cl, OCH3 (ortho and  meta)
sustituents. These are probably obtained from the 3,4- and 3,5- disubstituted 
benzoic acids. 
	Kindly send us these values or suggest a suitable reference.
	Thank you  ........................Shridhar R. Gadre
