Description
In a letter from Antoni van Leeuwenhoek to Thomas Gale. The
drawings are likely by Leeuwenhoek himself.
Fig. 1: is a model in bees wax of how Van Leeuwenhoek observed yeast in beer.
Fig. 2: the same wax model after rolling it in his hands. Van Leeuwenhoek describes that this is how he thinks globules in beer would look after fermentation of the beer.
Fig. 3: example of a glass tube which Van Leeuwenhoek filled with pepper and clean rain water. The tube is closed by melting. To Van Leeuwenhoek's great surprise, there he discovered life in the tubes after opening them again after five days. What he saw was colonies of bacteria.
