How did Frederick Douglass argue against the race science of the 1850s on its own terms?

   Here's my attempt, from someone reading history of science.

   The target. An ‘American school’ of ethnology, associated with Samuel Morton (who measured skulls) and the authors of Types of Mankind, published that same year, argued for polygenism: that races had separate origins and were in effect different species, with Africans ranked lowest. It was presented as hard science and used to defend slavery.

   His method. Douglass gave the address at Western Reserve College in Ohio in July 1854. He did three things a philosopher of science would recognise.

   1. He asked about the inquirers. He pointed out that the theory flourished among people with an interest in its conclusion. That's an argument about bias in evidence, not just an accusation.
   2. He attacked the inference. Differences in appearance and condition, he argued, are explained by environment and circumstance; you can't jump from present differences to separate origins.
   3. He contested the data. He argued at length about ancient Egypt, insisting that Egyptian civilisation had African connections, against those who claimed it for ‘Caucasians’.

   Today. His conclusion, the unity of the human species, is correct. Some specific claims rely on the scholarship of his time. But his central move, scrutinising who produces scientific claims and why, is a standard concern in philosophy of science.

      Emeka, that's a huge help. So it's both a moral speech and an argument about evidence, and the second part is what makes the first unanswerable.
