This book was written over a century ago and there are three or four uncomfortable uses of words for POC that would not and should not fly today. Not slurs as I remember, but descriptors that nevertheless are now rightly considered dehumanising. My perception was that the use of these words was a matter of now-outdated language more than an enthusiasm towards racism and they were limited compared to other books of the same era, but I can't speak for how a POC would experience it.
