The Unicode block for Tagbanwa is U+1760–U+177F: Tagbanwa script Tagbanwa, is one of the scripts indigenous to the Philippines, used by the Tagbanwa people and the Palawan people as their ethnic writing system and script. The Tagbanwa languages (Aborlan, Calamian and Central), which are Austronesian languages with about 25,000 total speakers in the central and northern regions of Palawan, are dying out as the younger generations of Tagbanwa are learning and using non-traditional languages, such as Cuyonon and Tagalog, thus 	Tagbanwa script

Education. Hartline did his undergraduate studies at Lafayette College in Easton, Pennsylvania, graduating in 1923. He began his study of retinal electrophysiology as a National Research Council Fellow at Johns Hopkins School of Medicine, receiving his medical degree in 1927. Career and research.

Bronk at that time. In 1940–1941, he was Associate Professor of Physiology at Cornell Medical College in New York City, but returned to Penn and stayed until 1949. Then he became professor of biophysics and chairman of the department at Johns Hopkins School of Medicine in 1949.

Hartline investigated the electrical responses of the retinas of certain arthropods, vertebrates, and mollusks, because their visual systems are much simpler than those of humans and thus easier to study. He concentrated his studies on the eye of the horseshoe crab (Limulus polyphemus"). Using minute electrodes, he obtained the first record of the electrical impulses sent by a single optic nerve fibre when the receptors connected to it are stimulated by light. He found that the photoreceptor cells in the  eye are interconnected in such a way that when one is stimulated, others nearby are depressed, thus enhancing the contrast in light patterns and sharpening the perception of shapes. Hartline thus built up a detailed understanding of the workings of individual photoreceptors and nerve fibres in the retina, and he showed how simple retinal mechanisms constitute vital steps in the integration of visual information. Awards and honors. Hartline was elected a Foreign Member of the Royal Society (ForMemRS) in 1966. He was awarded the Nobel Prize in Physiology or Medicine in 1967. Personal life. Hartline married Elizabeth Kraus Hartline in  1936. They had three children.
