held up his apron with one hand, as one would a skirt, and becoming 

 interested in this phenomenon, I saw that the band around his neck 

 was so long that the rubber apron nearly touched the floor, and the 

 string, which should have gone around his waist, tied his knees to- 

 gether so that it was impossible for him to take a long step. I asked 

 if I could not shorten the neck band for him and explained what 

 seemed to me to be the advantage of doing this, but he only looked 

 at it in a dreamy sort of way and said that it was all right as it was, 

 and it stayed that way as long as I was there. 



When one of these blood pressure experiments was over, the record 

 was rolled out on the floor, often rimning the entire length of the large 

 laboratory and even out into the hall. Everyone would very seriously 

 gather about it and walk up and down the record looking for results. 

 No one ever seemed to be the least bit aware that this was not the 

 accepted method of carrying out such experiments. 



The laboratory was well equipped for special chemical work, but 

 except for this one kymograph there was almost nothing in the way of 

 apparatus. There was one microscope in the department in use, and 

 that belonged to me. After some ten years when I needed a micro- 

 scope badly and everyone was using mine, I asked the Professor if 

 the one which he had in his laboratory could not be turned to gen- 

 eral use. I had seen this in action only once. It was kept in a wooden 

 box done up in a brown cloth, tied with a stout cord, and the whole 

 thing wrapped in an old, white laboratory coat and locked in a case 

 in Professor Abel's room. He looked very much taken aback at such 

 a request on my part and asked what was the matter with the one we 

 were using. I told him that there was nothing the matter with it, but 

 that it was mine and that we needed another. He said, "But, Lamson, 

 the microscope that I have is a good one." When I answered that mine 

 was also, ten years ago before everyone used it, he looked at me hard 

 without saying anything, and then a quiet smile came over his face, 

 and he turned and walked away. In a few minutes he came back to 

 my room with the precious machine of his own and left it without a 

 word. 



We had no shop, and when I tried to make a perfusion apparatus 

 and needed to make a thermostat, the only tools which could be found 

 were a hammer with a split handle, a screwdriver, and a keyhole saw 

 with half the blade broken off. With this outfit I managed to put 

 together a thermostat made out of a soap box, which worked sur- 

 prisingly well until one day when I was out of the room I heard a 

 great commotion and someone shouting, 'Tire!" I came in just in
