Question: "Which discipline of natural history would be last alphabetically?"  Context: "A genre that greatly rose in importance was that of scientific literature. Natural history in particular became increasingly popular among the upper classes. Works of natural history include René-Antoine Ferchault de Réaumur's Histoire naturelle des insectes and Jacques Gautier d'Agoty's La Myologie complète, ou description de tous les muscles du corps humain (1746). Outside ancien régime France, natural history was an important part of medicine and industry, encompassing the fields of botany, zoology, meteorology, hydrology and mineralogy. Students in Enlightenment universities and academies were taught these subjects to prepare them for careers as diverse as medicine and theology. As shown by M D Eddy, natural history in this context was a very middle class pursuit and operated as a fertile trading zone for the interdisciplinary exchange of diverse scientific ideas."  Answer:
The answer to this question is:
zoology
