Mises has the 1874 edition, the OLL version is the 1884 edition. The only difference I can spot is a few years/numbers, and only a few tweaked sentences.

Mr. Baring, in his evidence before the Bullion Committee, and Mr. Huskisson in his speech on the motion above referred to, bear ample testimony to the repetition of the old phenonemon of speculation under inflated paper issues.
Page 301: par. 0 (near middle of page): committee
It is true that the proposition of Mr. Western for a committtee of inquiry into the action of the bill was negatived by a heavy vote, but it appeared that there were some active and influential men who wanted to return to paper, and others who thought a great mistake had been made in not accepting the depreciation and reducing the standard, and they were supported by a clamorous party suffering under distress.

Page 22: par. 3: indefatigable
Virtue is free and indefatigible, and accompanied with concord and gracefulness; whereas pleasure is mean, servile, transitory, tiresome, and sickly, and scarce outlives the tasting of it.
Page 24: par. 5: indefatigably
A good man is happy within himself, and independent of fortune, kind to his friend, temperate to his enemy, religiously just, indefatigibly laborious; and he discharges all duties with a constancy and congru-ity of actions.

Aided, however, by the valuable materials collected and arranged by the labours of his distinguished predecessors, here referred to, and proceeding in the same path, our author, with the closeness and minutenes of attention due to this important study, has succeeded in examining under all their aspects, the general facts which the groundwork of the science presents, and by rejecting and excluding the accidental circumstances connected with them, has thus established its ultimate laws or principles.

Page 467: par. 2: fortiori
The direct taxation of the productive classes must, à fortìori, affect the consumers of their products, but can never raise the prices of those products so much, as completely to indemnify the producer; because, as I have repeatedly explained, the increased price abridges the demand, and the contraction of the demand reduces the profits of all the productive agency, that has been exerted in the supply.
Page 469: par. 0: unlooked for
But, if any unlooked-for occurrence should happen to lower the demand for his product, he will be glad enough to take the tax upon himself, for the sake of quickening the sale.
Page 487: Footnote: regularly
Economy in the national expenditure is the only thing that can mitigate the pressure of taxation upon the British nation; yet were economy enforced, how is that system of corruption to be upheld, through which the interest of the minister of the day reglarly prevails over that of the nation?
By the time I was almost complete with the new EPUB of this book, I noticed that Mises already created an EPUB version in 2011. I compared both, fixed up typos, and overall I believe my version is superior (and much smaller filesize (1233 KB -> 592 KB).
Most of the filesize difference was because of their poor bloated "grayscale" JPGs. I created some proper B&W PNGs, which are vastly superior quality, and much smaller filesize.
Page 129: par. 2, second sentence: guaranteed
I oppose cartels in principle, since a sound and well-intentioned social market economy—in which the word ‘social’ is consciously stressed—can only be guaranteeed if as a result of competition the superior achievement gains over the inferior, and if through this form of competition what is needed is supplied in the best possible quality and quantity and at the proper price.
Page 220: par. 2, middle of par.: Keynesian
One should, for example, recall Keynsian principles, ‘deficit spending’, the ‘policy of cheap money’, and all that goes with it, to understand that it will be extraordinarily difficult to arrive at acceptable common action and a unified rigorous policy in this sphere.
Page 140: "vis à vis" changed to "vis-à-vis" to match page 235's usage.
If my conception of cartels is interpreted as enmity vis à vis the businessman, I must doubt the seriousness and honesty of such an interpretation.
Page 67-68: Tables: The tables look to have the same headers (years), and the same exact categories. The numbers are slightly different in both tables, but the second should be a continuation of the first.
Page 254: par. 1: "dirigistically"? I did a Google search and it only found 16 hits. I am not too sure if this is the actual word?
A Europe which is dirigistically manipulated will itself paralyse the powers of resistance against the spirit of collectivism and allow the feeling for the benefits of freedom to perish.
Notes chapter was spread throughout the book so that each footnote was at the end of each chapter.
I was looking through a backlog of videos, and I stumbled upon Jeff Tucker's review of this book here: http://vimeo.com/55406139. I always spotted it in the pile of PDFs/EPUBs, but never knew one thing about it. Jeff Tucker's description of this book as the perfect follow-up to "Economics In One Lesson" definitely made me excited to take a look back and clean up this EPUB.
Update on 07.09.2013: Compared with LFB version, fixed a few more typos.
Page 25: par. 1, about 2/3rds of the way down: himself
If he does not do this and allows himsef to be dazzled by appearances, by the example of other countries or other times, etc., then he runs the risk of obtaining, instead of a greater, a lesser return on his investment, to his own detriment and that of the market.

For the alleged unjust distribution of wealth socialism, in all its various forms, does not seek corrective measures; this is rather the object of the so-called social reform movements, and more especally of the “planned” or “controlled” economy.
Page 14: par 2, near very bottom of page: goodness
There is a sort of goodnesss here, a longing for love and compassion, a belief that men should help each other, a sort of high-minded missionaryism which is aimed at obviating the miseries of the poverty-stricken, the lowly, the poorly paid and the humble.

The term “money economy’ must not, therefore, be taken to mean something different from the exchange economy, but as something essentially the same, though with special emphasis on the importance of money in it.
Page 77: par. 1, last sentence: particular
When the normal supply of a commodity is cut off as a result of certain extraordinary events, and its price consequently rises to an unusual level, it is found that even those households which hitherto had never thought of restricting their demand for that patricular commodity must now diminish their consumption of it.
