    THE NATURALIST'S LANDSCAPE: PHILIP HENRY GOSSE IN THE EASTERN TOWNSHIPS, 1835-38 j.l. Little History Department, Simon Fraser University This is what I prayed for. A piece of land-not so very big, with a garden and, near the house, a spring that never fails, and a bit ofwood to round it off. -Horace RESUME Philip Henry Gosse faisait partie d'un groupe de colons anglais instruits qui, dans les annees 1830, se sont laisses seduire par I'idee de devenir « gentilshommes rultivateurs » dans les Cantons de [,Est. Comme les autres, Gosse etait prindpalement attire par Ie pittoresque du paysage. n n'a pas tarde aretourner en Angleterre ou if est devenu un naturaliste renomme apres la publication de The Canadian Naturalist, ouvrage base sur I'observation minutieuse des plantes et des animaux des environs de sa ferme du canton de Compton. Cet article examine les descriptions faites par Gosse du paysage local et presente son regard porte sur les relations entre la sodete humaine et fa nature. ABSTRACT Philip Henry Gosse was one of a number of well-educated British settlers seduced by the vision of becoming gentlemen farmers in the Eastern Townships during the 1830s. Gosse, like the others, was attracted primarily by the picturesque landscape. He soon returned to England where he became a widely read naturalist after publishing The Canadian Naturalist, which was based on careful observations of the plants and animals in the vicinity of his Compton Township farm. This paper examines Gosse's descriptions of the local landscape and discusses his attitude to the relationship between human society and nature.

  • Aquacultue OPEN COURSE: NOTES PART 1
    OPEN COURSE AQ5 D01 ORNAMENTAL FISH CULTURE GENERAL INTRODUCTION An aquarium is a marvelous piece of nature in an enclosed space, gathering the attraction of every human being. It is an amazing window to the fascinating underwater world. The term ‘aquarium’is a derivative of two words in Latin, i.e aqua denoting ‘water’ and arium or orium indicating ‘compartment’. Philip Henry Gosse, an English naturalist, was the first person to actually use the word "aquarium", in 1854 in his book The Aquarium: An Unveiling of the Wonders of the Deep Sea. In this book, Gosse primarily discussed saltwater aquaria. Aquarium or ornamental fish keeping has grown from the status of a mere hobby to a global industry capable of generating international exchequer at considerable levels. History shows that Romans have kept aquaria (plural for ‘aquarium’) since 2500 B.C and Chinese in 1278-960 B.C. But they used aquaria primarily for rearing and fattening of food fishes. Chinese developed the art of selective breeding in carp and goldfish, probably the best known animal for an aquarium. Ancient Egyptians were probably the first to keep the fish for ornamental purpose. World’s first public aquarium was established in Regents Park in London in 1853. Earlier only coldwater fishes were kept as pets as there was no practical system of heating which is required for tropical freshwater fish. The invention of electricity opened a vast scope of development in aquarium keeping. The ease of quick transportation and facilities for carting in temperature controlled packaging has broadened the horizon for this hobby.

En el Perú es escasa la información publicada de aspectos hematológicos de osteictios para su uso potencial como biomarcador fisiológico de respuesta subletal en bioensayos ecotoxicológicos. Los objetivos del presente trabajo fueron: 1) evaluar el efecto ecotoxicológico agudo del metomilo sobre el pez amazónico ornamental Corydoras arcuatus Elwin, 1939 (Callichthyidae) a 2, 4, 6, 8, 24 y 48 h de exposición, y 2) caracterizar los leucocitos de C. arcuatus, Corydoras leucomelas Eigenmann & Allen, 1972 y Corydoras leopardus Myers, 1933, y determinar los valores de referencia cuantitativos. Los bioensayos con metomilo se realizaron en envases plásticos de 1000 mL. Se encontraron valores de CL50 (mg IA -1 L ) de 10.84; 3.18; 0.28; 0.01; 0.002 y < 0.002 a 2, 4, 6, 8, 24 y 48 h, respectivamente. La TL50 a la concentración más baja de 3.2 mg L-1 fue 4.83 h.
