La pantalla se coloc6 sobre la extremidad superior de una asta, apoyada sobre una galera que habia cerca de la estacion astronomica y el punto en que debia yo situarme, se fijo atendiendo a la altura y azimut que tendria el Sol durante la totalidad, para que la pantalla cubriese exactamente el disco lunar la crom6sfera y corona interior.
Siguiendo en todo las recomendaciones del Profesor Pritcliett, cinco minutos antes de que la- totalidad comenzase 6 sea a la 1* 42 m p. M. (tiempo medio local)
..., me cubri la cabeza con un denso lienzo oscuro y asi permaneci hasta el momento en que un joven colocado cerca de mi, me dio aviso de que la totalidad habia comenzado. Rapidamente me descubri, pero desgraciadamente al hacerlo, probablemente desvie" algo la cabeza, pues una luz viva la de la corona interior hirio mi vista deslum- brandome. Inmediatamente cerre los ojos, permaneciendo asi algunos segundos mientras tanto me coloque en la posicion conveniente y en seguida dibuje el croquis num. 1, procurando que las rafagas 6 haces luminosas quedasen colocados respecto del disco y lineas de referencia que tenia la hoja en que lo ejecute", en su posicion y magnitud relativas, suponiendo que las lineas representasen la ver- tical y horizontal que pasaban por el centre del Sol durante la totalidad y el disco, la dimension aparente de la pantalla que segun su distancia a mi ojo y su diametro fue* de 1 8'.
