This work is divided into four parts:

• "The first, which occupies the first volume, contains a general description of Normandy, considerations about its climate, its people, their morals and habits, and the most common diseases that affect this province.
  Lépecq de la Clôture divided the entire province by region, according to the deposit of the mountains, the course of the rivers, the exposure, the elevation or the depression of the places. He described the character of the early Normans in comparison with the mores and customs of their descendants; the most general endemic diseases and those peculiar to each canton. He gave a brief account of the natural products found there, the nature of the common or mineral waters that flowed there, and the long series of epidemic diseases that were observed there.
  He made a description of the cantons of Rouen and Caen and obtained from his collaborators those of the canton of Évreux. He provided three life tables (Rouen, Lisieux and Évreux over 40 years) and made comparisons and reconciliations.
• The second part includes meteorological observations collected in Caen and Rouen during fifteen consecutive years.
• The third part presents the major constitutions of popular diseases in Caen from 1763 to 1768;
• The last part presents the diseases that reigned in the climate of Rouen from 1768 to 1777, and describes the various epidemics that occurred in Upper Normandy.
