This paper deals with the morphology of Pomacea caniculata (Lamarck, 1822) collected at Corrientes, Argentina. Comparison is made with Pomacea lineata (Spix, 1827) and Pomacea sordida (Swainson, 1823). The shell is globose, heavy, with greenish or horn-colored periostracum and dark spiral bands; apex subelevated, 5-6 whorls increasing rather rapidly and separated by very deep suture. Aperture large, rounded to subelongated; lip sometimes reddish; umbilicus large and deep; operculum corneous, entirely closing the aperture. Ratios: shell width/shell length = 0.78-0.96 (mean 0.86); aperture length/shell length = 0.68-0.77 (mean 0.72). Radula similar to other congeneric species. Testis and spermiduct as in P. lineata and P. sordida; prostate cylindric and short, cream in color as the testis. Penial sheath straight bearing a central outer gland deeply embedded in the tissue of its basal portion and a large wrinkled gland occupying 2/3 of the distal tip of its inner surface; the rigth margin of the sheath overlaps the left one until 2/3 of its proximal end. Female reproductive apparatus similar to that P. lineata; vestigial male copulatory apparatus (penis and its sheath) present in all females examined.

Pensar en William Shakespeare, apropar-se a una de l'obres què més tinta han fet córrer, se'ns presenta com voler trobar una agulla en un paller. Amb tot, aquest treball de recerca a volgut discernir la dramatúrgia de Shakespeare, des de l'òptica espacial i estètica. El seu marc, a l'Anglaterra renaixentista -ss,XVI-XVII-, és: l'abundosa legislació -important l'Acta promulgada l'any 1572, per la reina Elisabet I-; la tipologia constructiva i formal del Lloc del Teatre, amb la formulació empresarial què se’n deriva; l'altre element, la participació de l'espectador implícit. Conclusivament, com l'artialització shakespeariana s'insereix, podem dir, 'dramatològicament', dins l'historiografia general del teatre.

This paper examines the explanation of commercial crises offered by William Huskisson in 1810 in the wake of the debate on the Bullion Report. Huskisson argued that the suspension of convertibility made it possible to extend issues of paper currency beyond its proper limits. Such an expansion, being in the interest of all parties concerned, would actually take place and stimulate excessive speculations, which would eventually prove unsustainable and bring generalized ruin and distress. Although some elements of this explanations were not new (having been anticipated by writers sucha as James Currie in 1793, William Roscoe in 1793, William Anderson in 1797 and an anonymous in 1796), Huskisson's explanation is more systematic and better organized, and his emphasis on the endogenous character of the crisis and on the instability of the dynamics of trade and credit makes it an interesting foreshadower of the theories of crises that were advanced half a century later.

Some aspects of torpor have been studied among captive Suncus etruscus by recording the nest temperature. Torpors show a circadian pattern and occur spontaneously or can be induced by food shortage. Body temperature can be controlled during torpor, remaining relatively high at low ambiant temperatures. At 20° C, spontaneous torpors seem to be less deep than induced tropors, but both show similar patterns at 5-8 ° C. Spontaneous torpors begin between 01°° and 06°°, whereas the onset of diet induced torpors seems to depend also on food exhausting. The rates of activity (A) and of torpor (T) show under constant conditions a daily variability. Increase of T is linked with a decrease of A and the relationship could agree with A(%) = Ao( 1-T/100), where Ao is daily rate of activity when T = 0. Occurence of torpor among other Soricidae, possible occurence among free living Suncus etruscus and energy saving are discussed
