Sweet Paddy:

I'm wondering what you did today. We missed you sadly at waffle time and I'm not any good at all at cooking waffles. Two stuck miserably this morning. It has been a warm sunny day. There has still been no rain here. Imagine that- no rain since last June- the first-.

I'm beginning to worry for fear you won't like us to go to Deep Springs, but you would probably remember to telegraph a night message Wednesday if your objections are violent. I think it would be all right. If only it isn't too cold. We'll take food of course. Lola's Bob will recharge our battery.

Yesterday morning Lena Weinbaum came. She is going to school. She said Sidney was working harder, too. Margaret and Chester brought me a little box, candy. Everyone wants you to return. [Coryell] is lonesome for you I think.

Little Crellie weighed 17 ½ pounds today. He is beautiful little fellow. I don't know what to do about Linus. The New York Philharmonic was fine today- an

all Russian program.

The boys said that the X-Ray lab was just humming with industry and that they like Buckman very much. Maybe he would like to go with us- still that is too many. Eyster is an amusing fellow. He shouldn't have that moustache I've decided.

10.15 P.M.

My darling sweetheart:

Shomaker called this evening and asked if I would like to go with all of them to Dabney to listen to some records. So, Shomaker, Eyster, Wilson, Levy called for me and we all went and heard the marvelous "Eroica" symphony besides some Glück and Mendelssohn. They brought me home and then I said it was time for them to go to work so didn't ask them in. I wanted to send my night letter to Kimpton and also wanted to write to you. These boys are sweet. Isn't it amusing that Shomaker is the spokesman although Eyster does most of the talking and is more glib? Peter and I saved last Sunday's "Rosie's Beau" for you but then Lola threw it away. The Beau says. Darn he has told Rosie good-by- but he is lonesome- he'll telephone- them he has just telephoned, but is lonesome again so will write a letter and asks the boy to take it to Rosie. The boy says he'll drop by on his way home from work with the letter, but Rosie's Beau says he'll see Rosie himself then. The Boy is overcome by this devotion. We'll send you todays which we also cut out. I'll be glad when you come home to read the funnies to the children. They are awful things. Good night- Ava Helen.

Sunday, 12.

Dearest sweet little Ava Helen:

I slept well last night, rising at 9, and breakfasting on grapefruit & waffle & coffee. Then I talked with Landsteiner till 12, when he left in a taxi for the train. (Last night as I was writing you it must have been snowing heavily, for when I started home there was a blanket of about 3 inches of fresh snow on the ground - it had cleared, however. This morning I saw it snow heavily for about an hour, so that we have about 4 inches or more now. I haven't walked in heavy ^falling snow, however. The cars have trouble on the slippery hills, so I didn't try to borrow one to take L. to the station.) When he left Professor Shaffer, Philip's father, came and talked to me for an hour. Philip wants to be married, and will be, I think. His father thinks that he perhaps should, since he is so serious - the father had forbidden it before. He says the girl seems nice, but isn't the one he would pick for his boy. Philip has gone with her for four years while she was at Har Radcliffe. Prof. Shaffer says that she is a smart girl, getting better grades than Philip. He let me

read a long letter from Philip to him - such a serious youthful letter that I felt very happy. He mentioned you and me, saying that we seemed happy together and went around hand in hand, and that he overheard people talking about the love birds on the campus who turned out to be us!

I had dinner at 1 ¹⁵ and at 2 ³⁰ came to the Lab and read the Sunday paper till 3 ³⁰ , and then worked till 6, went to the House for supper, returned here and wrote more. Till Now I am rather cold, so I'll trot home - or rather walk carefully so as not to slip. No one else has been in the Lab today. I have nearly finished Chap.III and have parts of V written. I love you. I'm not going to leave you again, because we were meant to be together. You are my own little antibody. I have found that there is evidence (which I interpret as showing) [this is written in the margin] that antigens have active groups which stick out like this [picture of a round molecule] and that antibodies are formed to fit them like this [another picture of an invagination]. Your own loving

Paddy
