FIRST EDITIONS of Vallisnieri’s first two books; the first discusses some curious stones found in the brains of cattle; the second is on parasitic worms of the human body, and is an important essay in parasitology. Vallisnieri proved that these worms were not due to spontaneous generation, but grew from eggs. He was the leading researcher in the field of parasitology at the beginning of the eighteenth century, and played a fundamental role in the field of helminthology and entomology (Penso, La conquête du monde invisible, pp. 191–199, in translation, illustrating several of the figures from Plate 3 of this book).
