"This is "a round unvarnished tale" of the chequered adventures of an African who early in life was torn from his native country by those savage dealers in a traffic disgraceful to humanity and which has fixed a stain on the legislature of Britain, which nothing but its abolition can remove. With what propriety can we boast of our humanity and love of justice whilst we continue a commerce inconsistent with either? [...] The narrative appears to be written with much truth and simplicity. The author's account of the manners of the natives of his own province (Eboe) is interesting and pleasing; and the reader, unless perchance he is either a West-India planter or Liverpool merchant, will find his humanity severely wounded by the shameless barbarity practised towards the author's hapless countrymen in our colonies."

"Reinforcing these were still rarer items of Africana and foreign Negro interest, the volumes of...Gustavus Vassa's celebrated autobiography that supplied so much of the evidence in 1796 for Granville Sharpe's attack on slavery in the British colonies...The cumulative effect of such evidences of scholarship and moral prowess is too weighty to be dismissed as exceptional."

"I hope to have the satisfaction of seeing the renovation of liberty and justice resting on the British government, to vindicate the honour of our common nature."
