When Prof. Deemer inspects the animals in his cages, he changes the card (on the clipboard) showing the age of the first animal (white rat) from 5 to 6 days and writes that the rat received the second injection on the 6th day; however, even though he holds the needle in his hand, he does not give the rat an injection. He then inspects the clipboards for the remaining animals yet does not change the date of the age for any of them.
