John Winthrop's proposal respecting electrical globes and jars, ca. 1758

In this proposal, John Winthrop explains the need to replace damaged "electric globes" used in the College's collection of scientific apparatus. He states that Benjamin Franklin, at the time residing in London, was willing to seek replacement globes for the College's collection. Winthrop then proceeds to assert that the College should acquire "square bottles, of a moderate size, fitted in a wooden box, like what they call case bottles for spirits" instead of the large jars included in the scientific apparatus, because those jars cracked frequently.

Short nomenclator or vocabular in English and Hebrew: composed alphabetically for the use and benefit of my pupils in particular and for the advantage of those who are desirous to obtain the knowledge of the Hebrew tongue in general, which may be that great help to understand not only ye sacred oracles in their original, but even any Jewish author (so far as concern owns) as also it may give great insight in ye tongue to those, as to compose it, a work altogether new, [ca. 1735]

Headed on the first page with the words "Nomenclatura hebraica," this handwritten volume is a vocabulary with the Hebrew word in the left column, and the English translation on the right. While the book is arranged in sections by letter, individual entries do not appear in strict alphabetical order. The small vocabulary varies greatly and includes entries like enigma, excommunication, and martyr, as well as cucumber and maggot. There are translations of the astrological signs at the end of the volume. Poem written at the bottom of the last page in different hand: "Women when good the best of saints/ that bright seraphick lovely/ she, who nothing of an angel/ wants but truth & immortality./ Verse 2: Who silken limbs & charming/ face. Keeps nature warm."

Letter from John Quincy Adams to his brother, Thomas Boylston Adams, 1786 July 2

This letter was written by John Quincy Adams on July 2, 1786 to his younger brother, Thomas Boylston Adams, who was then staying with their uncle, the Reverend John Shaw, in Haverhill, Massachusetts. In the letter, John gives Thomas advice on life as a student at Harvard, instructing him to choose his friends carefully, to favor those who are virtuous and studious over those who are idle and prone to vice, to maintain an "unblemished moral reputation," and to spend as much as six hours each day studying in order to excel as a scholar.

Rabbinical manuscripts of Judah Monis, ca. 1700s

This leather-bound volume contains ten handwritten Hebrew texts presumably compiled by Judah Monis in the early 18th century. The pieces range from three to 150 pages on different sized leaves and appear to be in multiple hands. The last page of the volume has the struck-through inscription, "Judah Monis' Book" and accompanies a 44-page text. The texts are unattributed and undated, but have been identified as transcriptions of cabalistic writings and include a short biography of Isaac Luria (1533-1572) and extracts from the work of Luria, Hayyim ben Joseph Vital, Jacob ben Hayyim Zemah, Abraham ben Isaac of Granada, and Naphtali Bachrach. The transcriptions appear to be unattributed and undated.
