throughout all of the periods. Several slight motions were reported by the 

 observer. The third period seemed very long to the subject. He was sleepy 

 in the period directly following the taking of food, but did not go to sleep. In 

 the intermission between the sixth and seventh periods he sat up for a time and

said he felt quite tired. In this intermission, also, he drank a glass of water 

 containing 4 grams of sodium bicarbonate. The subject urinated at 7 a. m.,
