Dear Enrique, I enclose the letter to reply the commenting letter of Modesto Varas.
I thought appropiate to reply, in accordance with your proposal. It took me a bit to response because Modesto's letter is quite confusing, but I think positive to have letters on the Journal.
If you consider opportune to comment on it, please don't hesitate to let me know. Thank you so much.
