Collection of the most important works of this great biologist Spallanzani, remarkable not only for his hypotheses, but for his imagination in terms of experimental method. The opuscules contain the Expériences sur la digestion, which are not found in the original, in which Spallanzani demonstrates the importance of gastric juices in the digestive process. He will also demonstrate that the theory of spontaneous generation is false, discovers the secret of fertilization between a spermatozoid and an ovum, that of regeneration in certain animals; he will perform the first artificial insemination on a female dog. We thus owe him numerous advances in the sciences, whose effects would not be felt until much later, but above all he marks his era through his scientific rigor and demonstration protocols that reveal an inventiveness and clairvoyance that seem inexhaustible.
