PRACTICAL BIOLOGY My grand daughter in Australia was very excited when she was given a live goat for dissection. She watched the heart beating . This gives me the idea that here in India too , we can give this chance to our students. Take them to a butcher. He will allow them to cut it. A fowl or goat may be dissected at Christian homes. The presence of a teacher is essential to explain the different organs . Any number of lessons in the text will not serve this purpose. Snakes are killed unnecessarily , because they are our friends ; they eat rats. After killing them no one dissects them. I too like to see the inside. I know that their lungs occupy almost the whole of the body. That is why they can run so fast . I like to see their sex organs. One cannot recognize which is male or female . Their digestive juice is the most powerful among animals . They dissolve even skeletons. We never see their droppings!
