These are primarily letters, with some receipts for medical services rendered included. They relate to the general social and intellectural life of Philadelphia and to publications on medical topics. Many of the letters are introductions to Europeans when Pennock first visited there. Letters dated post-1867 are to relatives and colleagues (?).
