"Vivisection" by Albert Leffingwell, M.D. is a scientific publication written in the late 19th century. The book discusses the controversial practice of vivisection—performing experiments on live animals—debating its ethical implications and utility in medical education and research. It seeks to address the moral dilemmas associated with such experiments while evaluating the actual benefits they provide to the field of medicine. In the book, Leffingwell presents a critical examination of vivisection, emphasizing the often severe pain inflicted on animals during these procedures. He articulates the argument that many vivisection practices do not yield significant results that justify the suffering caused, pointing out that while some physiological knowledge has been gained, it has not led to substantial advancements in therapeutics or the treatment of human disease. Addressing the opposition between scientific advancement and moral responsibility, Leffingwell advocates for greater oversight and restrictions on vivisection, particularly in educational settings, and calls for a re-evaluation of the practices that may desensitize medical students to suffering. Through a blend of personal observations, statistics, and appeals to ethical considerations, he argues for a more humane approach to scientific experimentation.

"Jaw Musculature of the Mourning and White-winged Doves" by Robert L. Merz is a scientific publication written in the early 1960s. The book focuses on the anatomical study of the jaw musculature in two species of doves, the Mourning Dove ("Zenaidura macroura") and the White-winged Dove ("Zenaida asiatica"). It aims to contribute to the understanding of the evolutionary relationships between these species by analyzing their musculature and cranial structures. The publication provides a detailed examination of the jaw muscles of the selected doves, comparing their anatomical structures and functions. Merz dissects and measures specimens to highlight similarities and differences in jaw musculature that may indicate evolutionary relationships. The findings reveal that while there are slight variations, especially in the size of certain muscles like the "M. pseudotemporalis profundus", both species exhibit a general homogeneity in their anatomical features. The study also suggests that the differences in jaw musculature may correlate to differences in feeding habits, such as the White-winged Dove's adaptation for nectar-feeding, hinting at deeper evolutionary connections between the genera. This work concludes by advocating for the potential reclassification of the Mourning Dove within the genus "Zenaida", based on the anatomical and functional similarities identified.
