Mechanochemistry and Enzymology

　I wish to thank you for the opportunity which you gave us to come to your meeting and have a talk with you here．We regret very much not to have been able to come to the Conference which, as I have heard from many guests from abroad, was a great success；we see from the proceedings that a great number of very important people reported there, so we have lost much by not being able to be present．We must make our excuses for coming to the present meeting completely unprepared．We have not been able to prepare anything reasonable beforehand so it will be almost a kind of improvisation．
