Set of the first two volumes of Maclure's Opinions..., lacking the third volume, which is usually not found together with the first two, the third volume is accorded a separate entry in Howes in acknowledgement of that fact. Maclure was born in Scotland and became an American citizen in 1803. Maclure was active in the scientific and intellectual circles of Philadelphia. He also travelled extensively in the United States and Mexico. He hoped to establish an agricultural school and sought help from Robert Owen and his colony of New Harmony. Maclure's correspondence from the New Harmony period on economic, social and political subjects was published there as his Opinions.
