I replied that I could not say that; our hands were still free, and we were considering what our attitude should be. All I could say was that our attitude would be determined largely by public opinion here, and that the neutrality of Belgium would appeal very strongly to Public opinion here. I did not think that we could give a promise of neutrality on that condition alone. The Ambassador pressed me as to whether I could not formulate conditions on which we would remain neutral. He even suggested that the integrity of France and her colonies might be guaranteed. I said that I felt obliged to refuse definitely any promise to remain neutral on similar terms, and I could only say that we must keep our hands free. I am, &c. E. GREY.

Sazonof, dated the 31st July, which are as follows:-- "The Austro-Hungarian Ambassador declared the readiness of his Government to discuss the substance of the Austrian ultimatum to Servia. M. Sazonof replied by expressing his satisfaction, and said it was desirable that the discussions should take place in London with the participation of the Great Powers. "M. Sazonof hoped that the British Government would assume the direction of these discussions. The whole of Europe would be thankful to them. It would be very important that Austria should meanwhile put a stop provisionally to her military action on Servian territory." (The above has been communicated to the six Powers.) No. 134. _Sir F. Bertie to Sir Edward Grey.--(Received August 1.)_ (Telegraphic.) _Paris, August_ 1, 1914.
