THE lectures that follow have already been delivered in Portuguese in Portugal and Brazil, and in Spanish in Uruguay, Argentina and Paraguay. In the course of the next four months, they are to be delivered in Chile, Peru, Colombia, Venezuela, Panama, Costa Rica, Nicaragua, Honduras, Guatemala, El Salvador, Mexico, Cuba, Dominican Republic and Puerto Rico.

It was my intention to deliver these lectures in Lima, Peru, but the Government of Peru refused to give me the necessary passport visa for a stay. During my visit in 1929, towards the end of my course of lectures, which attracted large audiences, the Archbishop of Peru denounced my lectures as heretical, and threatened to excommunicate all Catholics attending them. As the Archbishop's pastoral was published in all the newspapers on the morning of my last lecture, there was naturally a great sensation. The inevitable repercussion came after my last lecture, when on my appearance at the entrance of the theatre to return to my hotel, a crowd of nearly 2,000 persons insisted on taking me in procession, as a demonstration of appreciation. I presume that, fearing a similar demonstration if I visited again, the Peruvian Government desired to placate the Catholic Party by refusing me permission for a stay in Lima.
