The original 1770 Two Farewell Sermons by Reverend Mr. Geo. Whitefield  

It is a small, thin book, about 7 inches long 

In the original leather binding. 

Does contain the original Portrait plate, and the end papers are the original marbled ones of the period, as well as the alternative letter for S, indicated this is an original copy, and first edition. 

These are two of the most historically significant parting addresses delivered by ⁠George Whitefield, the legendary 18th-century English revivalist who served as chaplain to ⁠Selina Hastings, Countess of Huntingdon. 

These sermons were delivered at the Chapel in Tottenham-Court-Road, on Sunday August, 27th, 1769; and at the tabernacle in Moorfields, on Wednesday August 30th, 1769, Immediately before his Departure for America. This would be his last crossing as he would die one year later. 

The most famous of these ⁠Parting Sermons is widely known as "The Good Shepherd" (based on John 10:27-28), where Whitefield pleaded with his congregations to take a final farewell of the world's lusts and remain faithful to Christ.

What makes this copy significant, apart from its condition and age is it was dictated in short hand as he was preaching, and Whitefield believed this short hand dictation was not accurate and did not accurately represent what he had intended. 

Whitefield strongly condemned this publication. Because they were transcribed without his consent or revision, he argued they contained inaccuracies, garbled phrasing, and made him "say nonsense". Similarly, his literary executor and biographer John Gillies vehemently disowned the shorthand texts and unsuccessfully attempted to buy up and pulp the entire print run to protect Whitefield's legacy. 

So many copies were purchased back by the publisher and destroyed.
