One of the small pleasures of this work is the connecting of minor dots. In this case, this is about some statement about Pakistan that M.A. Ispahani mentioned in a letter to M.A. Jinnah.
Briefly, in the Second Series, Volume X of Z.R. Zaidi's Jinnah Papers, item #28 is a letter from Ispahani to Jinnah, dated October 23, 1943. An excerpt:
At the last Food Conference in Delhi, Chhotu Ram and Baldev Singh, who attended the Conference on behalf of Punjab would not give in on the point of food supply to Bengal on the question of price. This had a very bad effect, so much so that you must have read in the papers what Lord Hailey had to say about Pakistan.
