you have mentioned three authors above; has the first one done any scientific illustrations?
Yes, a collection of her fungus paintings at the Perth Museum and Art Gallery in Perth
Scientific illustrations and work in mycology
 Her work is only now being properly evaluated. Potter later gave her other mycological and scientific drawings to the Armitt Museum and Library in Ambleside, where mycologists still refer to them to identify fungi. There is also a collection of her fungus paintings at the Perth Museum and Art Gallery in Perth, Scotland, donated by Charles McIntosh. In 1967, the mycologist W.P.K. Findlay included many of Potter's beautifully accurate fungus drawings in his "Wayside & Woodland Fungi", thereby fulfilling her desire to one day have her fungus drawings published in a book. In 1997, the Linnean Society issued a posthumous apology to Potter for the sexism displayed in its handling of her research.
where do guinea pigs come from in the wild They originated in the Andes of South America how do they look like? Guinea pigs are large for rodents; the common pet breeds weigh between when full grown and measure between in length which club is associated with it? Cavy clubs dedicated to the showing and breeding of guinea pigs have been established worldwide. what reference do they have in literature? "The Fairy Caravan", a novel by Beatrix Potter, and Michael Bond's Olga da Polga series for children, both feature guinea pigs as the protagonist. Another appearance is in "The Magician's Nephew" by C. S. Lewis: in the first of his "The Chronicles of Narnia" series, a guinea pig is the first creature to travel to the Wood between the Worlds. is there any specific program for their breeding? Yes, Peruvian research universities, especially La Molina National Agrarian University, began experimental programs

Beatrix Potter was interested in every branch of natural science save astronomy. Botany was a passion for most Victorians and nature study was a popular enthusiasm. Potter was eclectic in her tastes: collecting fossils, studying archaeological artefacts from London excavations, and interested in entomology. In all these areas, she drew and painted her specimens with increasing skill. By the 1890s, her scientific interests centred on mycology. First drawn to fungi because of their colours and evanescence in nature and her delight in painting them, her interest deepened after meeting Charles McIntosh, a revered naturalist and amateur mycologist, during a summer holiday in Dunkeld in Perthshire in 1892.

He helped improve the accuracy of her illustrations, taught her taxonomy, and supplied her with live specimens to paint during the winter. Curious as to how fungi reproduced, Potter began microscopic drawings of fungus spores (the agarics) and in 1895 developed a theory of their germinatio Botany was a passion for most Victorians and nature study was a popular enthusiasm.
