But this is the first time to kill people, and I feel uncomfortable. . . A life just passed away.

The teacher told us that we can use three methods.

1. Ether knocked it out: but it didn't die. I don't feel good when I'm alive. I didn't do it at first.

2. Drop its head: Drop its head on the table and kill it. I don't think a fall will kill you. It's cruel to throw a few times. I didn't do it either.

3. Acupuncture his brain (anatomical needle): destroy his nerves and let him die. The teacher actually suggested that we do so. I think it's good to do so. Pick it, twist it, and it won't hurt too much.

But I didn't expect it! Unexpectedly! I didn't kill it or stun it. Looking at the struggling frog, I thought maybe it just fell down, so I decided to throw its head on the table.

What a pity! What a pity! It was so energetic that I fell several times without killing it. I knocked it out with the last ether.

Well, I didn't know if I was dead or not during the autopsy, but I fainted. It's not moving. Kill the first one, and there will be nothing behind. Living is their wish, and dissection is our only process.

To sum up, the first thing to destroy bone marrow is to take a long and thick needle through the foramen magnum and extend it to the head, disturbing the brain. When I was holding a bullfrog, I obviously felt that it was punctured and deflated with relatively tenacious pilling (doing experiments in groups of four, sciatic nerve reflex activity)

After that, it is bound to bleed, so it should be washed with water. At this time, the frog has no vital signs, and then it will be cut open with scissors. It depends on what experiment it does to cut the knife.

I still can't do it the first time, but it's a task, so I can only do it as soon as possible to avoid more pain.
