This volume is from the voyage of the China Packet from Philadelphia to Canton, China, and return. The concluding statement reads: "One hundred & thirty days from Maccoa out of which time we had 30 Calm days, the longest passage I Ever had from China. With this Journal I have done and glad Am I."

These logbooks record two voyages (to Corunna, Spain, 1789-1790, and to Oporto, Portugal, 1791, and returns to Philadelphia), with observations of differences in temperature between air and water, especially when passing the Gulf Stream or any land or banks.
