Slavery by numbers in Kentucky 1840-1859

This article is from the March 31, 1860 edition of the Covington Journal and shows that the number of slaves in the state increased by over 45,000 over those two decades, but had decreased in the northern-most counties in the state.

Here is a screen capture of the article. It does not indicate the source of these records and I have not yet done any research to try to confirm these numbers (at the very least there should be census records from 1850 and 1860 and perhaps 1840 as well) but I thought it was an interesting article.
