I am stooped considerably and stand unsteadily on my legs; not that they are not strong, but the tendency of my feet to turn inward has increased, so that I walk for the most part on the outer edges. Their prehensile powers are developed, too, and they can pick up objects quite easily.

It is also interesting to note that my mental processes have not changed one whit—I can think as clearly and as deeply as ever. As I predicted, the serum does not affect the brain tissues; or, if it does, it does not keep them from functioning properly.

I have been hungry all day. The food Brock sent to me was not sufficient, especially as regards meat, and I must send up a note with the empty dishes for him to increase the amount.

June 19—This part of the experiment will stop tomorrow, for I shall then mix and administer the counter-agent.

Tonight, I see myself to be an eerie creature, half beast, half man. I am hard put to it to walk without supporting myself on the table and the backs of the chairs. So must our ancestors have looked when they swung down from the trees to achieve their first adventures on the ground and to conquer the world.

These five days, what with the many notes I have taken, will provide a fitting climax for the scientific book that I contemplate. How it will astound the world! What honors and distinctions may descend upon me! Fame is mine, certainly; fortune if I wish it, may follow.

So good night and good-bye, my primitive self, yonder in the mirror. Tomorrow I shall commence the journey back to the appearance of Dr. Lawlor, that I may immortalize you in all your fascinating grotesqueness.

June 20—How could I—oh, how could I not provide against this? With all the machinery of my experimentation evidently flawless, I must forget a single item—an item maddeningly simple, maddeningly obvious, and yet a thing that has proved my undoing.

Let me remain sane for a moment and marshal the incidents as they occurred. There is not much to tell. This morning I went to my shelf of chemicals for the ingredients to compound into the counteracting serum. My hands, which of course had become clumsy and primitive, seemed to have trouble in picking up the little vials, but this did not worry me as I began the combining of my materials. Two of them I mixed in a graduated glass and then reached for a pipette to administer the third.

But my unsteady manipulation did not allow the proper proportion to flow in. I released a drop too much, and though there was a corresponding effervescence, I could see that the mixture was a failure. I poured it out and tried again, with the same result. With growing uneasiness, I made a third attempt, and again my clumsy hands failed me.
