Dear Father
I send you the abstract; I am very sorry that I havnt been able to get it done before— I’m afraid you will find it very obscure: my German says it is obscure in the original; there are several things I cant make out—. I will bring the book on Sat. for you to look at the figures— I cant say that I think he proves his point, but as I cant understand what he means very often I cant judge v well. I shall come by the 5.5 on Sat fr Charig X.2
