Delphinium – cattle, horses

The lantern slides in Series II depict poisonous plant research, mainly showing the
effects of plant toxins on livestock. Most of these slides show livestock that have
ingested toxic plants. Many of the slides are labeled with the scientific name of the
subject plant, the animal type, the animal number, and the date and time of the
photograph. Sequences of images follow the course of a particular animal's reaction to a
plant toxin. A few of the slides show poisonous plants in their native habitats. Some
slides have charts, tables, maps, and figures related to poisonous plant research.
