In my opinion the book is as described and illustrated by the two example pages.
Indeed, it does exactly that. But is it correct?
Whilst it may not be what you were looking for it could be useful to other researchers trying to find the area their ancestor may have come from.
We will have to agree to disagree on that.
On the available page of the book, which is headed 'Alphabetical list of the most frequent of Scottish names' and then '(The numbers represent the proportion per 10,000 throughout the country)', I highlighted two names, and
Rosinish highlighted another, which we are researching in Angus or nearby but which, if you believe the available page of this book, do not occur in Angus.
The author looked at surname distribution in 1890, but the available page does not say where he sourced his data. I looked at the 1891 census; I doubt that there would have been any major shifts of population between 1890 and the date of the 1891 census, 5 April.
I looked specifically at the name Adamson, which Robinson's book says is 'South of the Forth and Clyde', and the incidence he found per 10,000 was 12.
There were 3146 Adamsons in the index to the 1891 census on SP. The total population in Scotland was 4,033,103. So there were just under 8 Adamsons per 10,000 population over the whole country, not 12 as this book suggests.

Argyll 0 0%

I also sorted by whether a county was north or south of the Forth and Clyde. This does present the occasional problem; for example Lanarkshire is clearly south of the Forth, but bits of it are north of the Clyde. I assigned Lanarkshire to south of the Forth and Clyde, and Stirlingshire and Argyll to north of Forth and Clyde.
The result shows that 62% of the Adamsons in the index to the 1891 census were
north of the Forth and Clyde, and only 38% were
south of the Forth and Clyde.
Therefore the information given for the surname Adamson on the available page of the book is significantly incorrect in every respect. The available page says that the incidence of Beattie is 13 per, 10,000, and that the name is found 'mostly in Dumfries-shire'. The 1891 census records 5006 Beatties, of whom 667 were in Dumfries-shire. (Including spelling variants, there were 5710 B(e)at(t)ie/ys in Scotland of whom 676 were in Dumfries-shire).
So the incidence of the surname Beattie without variants was just over 12 per 10,000, which is reasonably close to the 13 per 10,000 in the book. However only 13% were in Dumfries-shire; in other words, nearly 7 out of 8 Beatties did not live in Dumfries-shire in 1891.
Therefore the information about the distribution of the surname Beattie on the available page of the book is wholly incorrect. Now, it is perfectly possible that the information about all the rest of the 100 names in the book is correct in every detail. But I doubt it. It may also be that there is more useful information later in the book. But if you can see that there are such glaring errors on just this one page, can you trust anything in the rest of the book?
I wouldn't buy this book to light the fire with.
If you want to know the distribution of surnames in Scotland, there are lots of more reliable sources than this. Try
http://gbnames.publicprofiler.org/ - though this uses modern post codes rather than historical counties. And treat all such information with caution. Remember my tale of the English family who moved to Middlesbrough!
Or you can do your own research using the indexes to census, births, marriages and deaths on Scotland's People, as I did.
