. Lundwall has got the animal from a tailor who regarded it as a good omen. Blom describes it as beautiful with red eyes and almost transparent ears and not larger than Mus musculus. The feet have five toes of which three are twice as long as the others. The tail is like the one of ordinary mice and somewhat longer than the body. It is kept in a glass jar. Blom describes how the rat washes itself with its paws. Blom also writes that since the owner got her she has got two young ones twice, but he has not kept them. Blom writes that he is enclosing his description of the rat in Latin [fol. 61]. Blom also writes that he has tried to buy the animal, but the owner does not want to sell it. The owner promised, however, to send a white rat to Linnaeus if he gets hold of another one.

Blom writes that he is still in Stockholm and will not leave until next Monday.
