Wouldn't it be easier to actually look at a map?
The National Library of Scotland has an online facility which enables you to examine OS 6" maps from the 1888 to 1913 series. (It's for the whole of Great Britain, not just Scotland)
Start here
http://maps.nls.uk/geo/explore/#zoom=8&lat=53.6802&lon=-1.8118&layers=171
Click-&-drag the map until the relevant part of the country is in view.
Hold down the shift key and draw a rectangle around the area you want to examine. (Don't worry is it's not exact. You can still click-&-drag the zoomed area afterwards if needed).
Then use the blue '+' button, the top left of the map area, to zoom in further (again clicking-&-dragging to reposition the map if required).
