Miller, the article posted above is, I'm quite certain, the one you're thinking of. It's from Thomas' "Gun Book"--which is, indeed, a compilation of his articles (but from "Shooting Times", not "The Field").
From the article, it's obvious that Thomas' readers were confused by what Burrard wrote. (That's why I said that Burrard needed a better editor, because before he gets around to saying that the problem is the load and not the case, he goes on--at some length, some of which I quoted above--about the longer case resulting in increased pressure.) Thomas, in fact, makes a statement that can be interpreted the same way: "It cannot be too strongly emphasized that it is indeed dangerous, in general, to use cartridges whose unloaded case length exceeds that of the chambers of the gun." But he immediately explains that it's really the heavier load that causes the problem.
He certainly could have added, but didn't (or maybe it got edited out? Editors can do harm as well as good!) that Burrard came to the same conclusion. But both of them can be quoted out of context to make it sound as if the length of the case is the problem. In fact, the very title of Thomas' article--"Danger in Case Length"--would lead one to believe that there IS a danger in case length! A simple editorial change--"Danger in Case Length?"--would've made for a better and more appropriate title.
Given the number of times Thomas cites Burrard as an authority elsewhere in his books (along with quite a few other "gun gurus"), I don't think ego figured very much into Thomas' writing. Nor do I read that article as any claim by Thomas that he "invented the wheel" when it came to using longer shells (with appropriate loads) in shorter chambers. For that matter, credit doesn't go to Burrard on that score either. It was the Brit ammo manufacturers who figured it out. Both Burrard and Thomas were simply reassuring their readers that those PARTICULAR long shells were perfectly safe in their shorter-chambered guns.
And Bell added the reassurance that the same is true of reloads using modern components in longer cases. All made valuable contributions to our knowledge base.
