张元济先生致陈乃乾书信十七通,是我在征集整理陈乃乾先生遗著所发现。张、陈两先生同为浙江嘉兴人,虽然张老籍隶海盐县,陈老则籍属海宁县,但两县毗邻,相去不远,历史上两县的归属又屡次变更,故两地之人,历来互相视为同乡。乃乾先生自民国初 Mr. Zhang Yuanji wrote to Chen Naiqin in his 17 letters, which I found in the collection of Mr. Chen Naiqian’s remains. Zhang and Chen Liang are both Jiaxing natives in Zhejiang Province. Although Zhang Lao Ji was born in Haiyan County and Chen Lao was a native of Haining County, both counties are adjacent to each other and not far from each other. The ownership of the two counties in history has been repeatedly changed, People, always as each other as fellow. Naikan from early Republic of China
