Description

Nathan S. Engle’s Thesis on Menstruation and Related Materials

Overview

This collection is a digital assemblage of Nathan S. Engle’s 1849 medical thesis, An Essay on Menstruation, together with ancillary files produced during its digitisation. The primary document is a 13‑page English‑language thesis submitted to the Homeopathic Medical College of Pennsylvania on 25 February 1849. The collection also contains scanned TIFF images of each page, a binary Thumbs.db system file, and a thumbnail database. All items are held by Drexel University and were captured by the PINAX digital preservation platform.

Background

Nathan S. Engle, a homeopathic practitioner from New Jersey, authored the thesis while enrolled at the Homeopathic Medical College of Pennsylvania. Homeopathy, a 19th‑century alternative medical system based on “like cures like,” was gaining prominence in the United States during this period. Drexel University, located in Pennsylvania, has preserved the thesis since its creation and made it available through its institutional repository. The collection reflects contemporary medical debates on female physiology and menstruation, drawing on classical authorities and observations from the United States, England, and Scotland.

Contents

  • Thesis Text – A 13‑page manuscript covering the onset, duration, periodicity, and physiological explanations of menstruation from a homeopathic perspective.
  • Thesis Images – Thirteen high‑resolution TIFF files (hutheses1849engle_001.tif‑013.tif) that are faithful facsimiles of the original pages.
  • System Files – A 34‑kilobyte Windows Thumbs.db binary file and an associated thumbnail database, preserved to capture the folder’s visual state at the time of digitisation.
  • Metadata – Descriptive fields include title, creator, institution, date, language, subjects (e.g., menstruation, homeopathic medicine, female physiology), and provenance information.

Scope

The collection documents the complete content of Engle’s 1849 thesis and its digital representation. It covers the physiological aspects of menstruation as understood by mid‑19th‑century homeopathic scholars, with observational data from the United States and the British Isles. The collection does not include experimental data, clinical trials, or modern medical terminology. It is intended for researchers in medical history, homeopathy, gender studies, and archival science.

# Reorganization Summary

The files were organized into three distinct groups based on their content and purpose. The 'thesis_content_pages' group includes all JPEG files containing the textual content of Nathan S. Engle's thesis on menstruation. The 'thesis_tiff_images' group includes the corresponding high-resolution TIFF images of the thesis pages. The 'system_files' group contains system-generated files that are not part of the thesis content but are related to file management. This strategy ensures that all files are logically grouped based on their content and purpose, avoiding unnecessary duplication or meta-categories.

## Groups Created

- **thesis_content_pages**: Files containing the actual content of Nathan S. Engle's thesis on menstruation, including detailed discussions on the topic.
- **thesis_tiff_images**: High-resolution TIFF images of the thesis pages, corresponding to the content pages.
- **system_files**: System-generated files that are not part of the thesis content but are related to file management.
