Continuing the discussion, Leibniz thanked Leeuwenhoek for some sketches, sent earlier. He discussed further the function of the membranes, their sensitivity, and the influence of heat and cold on their functioning. He gave his thoughts about the occurrence of multiple births in humans and animals.

Leibniz had shared information obtained from Leeuwenhoek with "some good physicians".

Finally, he discussed the views of other microscopic researchers on the question of reproduction.

He did not mention students, apparently having finally accepted Leeuwenhoek's refusal.
