I learned soon enough that studying animals at this level was not in the animals’ best 21 .I remember one midterm exam in 22 each student was handed a large, freshly-killed frog and instructedto dissect and mark a set of body parts. I looked at the dead frog in front of me and was saddened that her lifewas taken away for such a slight 23 .
