" It is true that the conclusions of Pasteur were not once everywhere accepted. In England, particularly, objectores arose who advocated a belief in spontaneous generation, and these objections were not silenced until the English physicist Tyndall took up the experiments that Pasteur had been making and even more satisfactorily reached the same conclusion. But Tyndall's results were only those that Pasteur had reached before, and we recognize to-day that the only basis of the objections were the inaccuracy and lack of care with which his opponents performed their experiments. With brilliant rhetoric and loose experimenting, spontaneous generation was still advocated, but the disproof was given by Pasteur in spite of the fact that opposition still arose after the disproof had been reached. "
~ Herbert William Conn

Scientists who supported abiogenesis, such as English physiologist Henry Charlton Bastian and French naturalist Félix-Archimède Pouchet, openly criticized Pasteur’s methods of experimentation through publishing books and academic journals that supported their claims on abiogenesis. Experimentation methods were often inconsistent, generating a miscommunication between the two sides. However, Pasteur's experiments—with his specially designed flask—provided irrefutable evidence that spontaneous generation was scientifically impossible. ​​​​​​​
