<p>Prima rarissima edizione. Gli opuscoli qui raccolti contengono le osservazioni e le esperienze con cui lo Spallanzani riuscì a confutare la teoria della generazione spontanea propugnata da Needman e Buffon, dimostrando per primo la natura animale dei «vermicelli spermatici». Cfr. <span style="font-variant: small-caps;">Gamba </span>2449; <em>Heirs of Hippocrates</em> 984: «A long controversy with Needham and Comte de Buffon resulted in a series of essays, published in this two-volume work, in which Spallanzani rejected the then-popular theory of spontaneous generation [...]. Although the matter of spontaneous generation was not resolved by this book, it clearly foreshadowed subsequent experiments by other investigators which culminated nearly a century later in Pasteur's epic work»; <span style="font-variant: small-caps;">Morton </span>102:«Later confutation of the theory of spontaneous generation. Spallanzani's conclusions were similar to those expressed by Pasteur's nearly a century later»; <span style="font-variant: small-caps;">Prandi</span>,<em> Bibl. Spallanzani </em>36-37. Manca a <em>Cushing</em>, <span style="font-variant: small-caps;">Osler </span>e <em>Walleriana</em>.</p>
