In recent years historical research seems to be the State Historical Society's main function, although it was formed with the principal functions of collection, preservation and exhibition. Now, instead of simply attempting to make the largest possible collection of historical materials in one place, this society will now endeavor to compile, publish and distribute accurate and scientific historical literature. The book also lists publications, information on the library and on membership.

Spermiogenesis and the ultrastructure of the spermatozoon of the bothriocephalidean cestode Clestobothrium crassiceps (Rudolphi, 1819), a parasite of the teleost fish Merluccius merluccius (Linnaeus, 1758), have been studied by means of transmission electron microscopy. Spermiogenesis involves firstly the formation of a differentiation zone. It is characterized by the presence of two centrioles associated with striated rootlets, an intercentriolar body and an electron-dense material in the apical region of this zone. Later, two flagella develop from the centrioles, growing orthogonally in relation to the median cytoplasmic process. Flagella then undergo a rotation of 90° until they become parallel to the median cytoplasmic process, followed by the proximodistal fusion of the flagella with the median cytoplasmic process. The nucleus elongates and afterwards it migrates along the spermatid body. Spermiogenesis finishes with the appearance of the apical cone surrounded by the single helical crested body at the base of the spermatid. Finally, the narrowing of the ring of arched membranes detaches the fully formed spermatozoon. The mature spermatozoon of C. crassiceps is filiform and contains two axonemes of the 9 + '1' trepaxonematan pattern, a parallel nucleus, parallel cortical microtubules, and electron-dense granules of glycogen. The anterior extremity of the gamete exhibits a short electron-dense apical cone and one crested body, which turns once around the sperm cell. The first axoneme is surrounded by a ring of thick cortical microtubules that persist until the appearance of the second axoneme. Later, these thick cortical microtubules disappear and thus, the mature spermatozoon exhibits two bundles of thin cortical microtubules. The posterior extremity of the male gamete presents only the nucleus. Results are discussed and compared particularly with the available ultrastructural data on the former 'pseudophyllideans'. Two differences can be established between spermatozoa of Bothriocephalidea and Diphyllobothriidea, the type of spermatozoon (II vs I) and the presence/absence of the ring of cortical microtubules.

A finales de 1909, coincidiendo con el intento de procurar unas raíces clásicas a la lengua y literatura catalanas, Lluís Segalà i Estalella pedirá al poeta Joan Maragall su colaboración en la traducción y versificación en catalán de la Olímpica primera de Píndaro. Para ello, uno de sus alumnos, Pedro Bosch Gimpera, trabajará junto al poeta dando así inicio a una corta pero intensa relación de amistad y magisterio que tendrá su más perdurable expresión en la traducción y versificación de los Himnos homéricos. Escogida por la recién creada Sección Filológica del IEC como una obra emblemática para la difusión de las normas que debían regular el uso escrito del catalán, la edición sufrirá diversos avatares motivados por las divergencias surgidas entre Segalà y Bosch, así como por el apoyo que Maragall brindará a su joven amigo hasta su muerte en 1911. Reconstruida a partir de la correspondencia personal, la historia de la edición de los Himnos homéricos supone una aproximación a la figura de Bosch en la época en que la filología y la religión griegas constituían su objetivo de investigación, substituidas poco después por la prehistoria y la arqueología.
