RESUMO
In this article, I present and comment on two unpublished letters written by the Spanish engineer Carlos Mendizábal Brunet to Santiago Ramón y Cajal informing him of the development of a new device for three-dimensional cinema and asking for his approval. Fortunately, the answers given by Cajal to these two letters have also been preserved, and they reveal his interest in three-dimensional cinema; in the letters, he reported that he himself had designed a prototype capable of creating on a screen a feeling of 3-D relief, a subject about which he was always passionate.

In this article we present and comment on three letters written, respectively, by Fernando de Castro, Santiago Ramon y Cajal, and Justo Gomez Ocerin, concerning the imprisonment and liberation of the Italian scientist Giuseppe Levi in 1934. These documents reveal the great interest that Ramon y Cajal took in the problem and his intervention in the liberation of his colleague. In addition, they show that the controversy about collaterals between Golgi and Cajal was still alive and demonstrate that Cajal did not possess Golgi's original publication.
