Deterioration progressing. I have become absentminded.
Algernon died two days ago. Dissection shows my predictions were right. His brain had decreased in weight and there was a general smoothing out of cerebral convolutions as well as a deepening and broadening of brain fissures.
I guess the same thing is or will soon be happening to me. Now that it's definite, I don't want it to happen.
I put Algernon's body in a cheese box and buried him in the back yard. I cried.
