Jaw Musculature of the Mourning and White-winged Doves

Robert L. Merz

"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.

The Natural Philosophy of William Gilbert and His Predecessors

W. James (William James) King

"The Natural Philosophy of William Gilbert and His Predecessors" by W. James King is a scientific publication written in the mid-20th century. The book explores the contributions of William Gilbert, a key figure in the transition from medieval to modern natural philosophy, especially focusing on his work related to magnetism and electricity. It analyzes how Gilbert's theories were influenced by earlier scholarship and how he, in turn, laid foundational concepts for later scientific developments. The book delves into Gilbert's groundbreaking work, particularly his seminal text "De magnete," which provided extensive insights into the nature of magnetism. King traces the historical context of Gilbert’s work, comparing his views with those of his predecessors, including Aristotle, St. Thomas Aquinas, and other influential thinkers. The author argues that while Gilbert is often celebrated as a pioneer of modern physics, his ideas were deeply rooted in the scholastic traditions of his time. King's examination reveals the complex interplay between innovation and tradition in Gilbert's approach, illustrating how his interpretations of magnetic attraction and other phenomena represented a critical, yet transitional, point in the evolution of scientific thought.
