Vertebral Osteoporosis in Late Edo Japanese
Osteoporosis was discovered in three individuals out of nine skeletons excavated in Mukai, Tokyo. The materials were dated to the late stage of the Edo period. The severely deformed thoracic and lumbar vertebrae were from mature and elderly individuals. In the first case, the 8th thoracic to the 5th lumbar vertebral bodies showed the so-called “fish vertebrae.” The traces of Schmorl's nodes were also visible in the upper two lumbar vertebrae. Thi…
A Decapitated Human Skull from Medieval Kamakura
The present study reports on the examination of a decapitated human male skull with four upper cervical vertebrae and the hyoid bone, dating to the early Muromachi period (late 14th century), from Kamakura. The decapitation may have been the result of a sharp cut from the right rear. The cut runs horizontally into the second cervical vertebra and stops in the bone, after having severed both the spinal cord and the right vertebral artery. Superfic…
A human victim of volcanic eruption of Mt. Asama in 1783
Four hundred and sixty-six people were buried at Kambara Village of Province Kozuke (old name of Gunma Pref.), Japan, under the glowing avalanche of volcanic debris due to the violent eruption of Mt.Asama in 1783 (the 3rd year of Temmei), which was followed by the so-called "big famine of Temmei" in the eastern half of this country.Well known were those two ladies buried alive under the flow of volcanic debris at the foot of the stone stairs to K…
External genital organs in male mummies from Qurna, Egypt
The external genital organs were examined in 18 ancient Egyptian male mummies from the Tombs Nos. 317 and 178 at Qurna, Egypt, dating from the 18th Dynasty of New Kingdom to the Ptolemaic stage of the Graeco-Roman period. The penises were kept intact in only three out of 11 adult (27.3%) and in two out of three child mummies (66.7%). The observations showed that the ritual of circumcision in boys at puberty was widely prevalent in the ancient Egy…
Wedging of Lower Thoracic and Upper Lumbar Vertebral Bodies in Early Recent Japanese
An examination of the vertebrae of the early recent Japanese (in the 17th century) from Hitotsubashi Metropolitan High School Site, Tokyo, revealed that wedge-shaped vertebral bodies were sometimes found at the lower thoracic and upper lumbar, especially at the lowermost thoracic and uppermost lumbar, in males. The wedging of the vertebral bodies was, however, rarely present at those in females. The wedge-shaped vertebrae in question would common…
Note on the Technique of Decapitation in Medieval Japan
A detailed technique of decapitation by the sword in the Middle Ages could be elucidated from the skulls with the upper cervical vertebrae of two males from Imakoji-nishi site, Kamakura, Kanagawa Pref., Japan, which dated back to the Nanbokucho or early Muromachi period, i. e. the latter half of the 14th century. The observations showed that in both males the sword cut deep into the 4th cervical vertebra from the posterior right side and came a s…
Brain Size, Cranial Morphology, Climate, and Time Machines [and Comments and Reply]
A bioclimatic model is evaluated as an explanation of variation in cranial capacity among 122 ethnic groups. Distribution of absolute and relative endocranial volume is mapped. Significant correlations occur with all nine climatic variables examined. Major foci of adaptation occur with solar radiation, vapor pressure, and winter temperature. Global mean trait increase is 2.5 cm per degree of equatorial distance. The interactive geometry between c…
Sapienization and Speech [and Comments and Reply]
Middle Pleistocene erectus skulls differ from ours in fifteen discrete traits, primary among which are their smaller cranial capacities, flatter and more strongly constructed braincases, larger and more anteriorly projecting faces, and inflected mastoid processes. Back to 40,000 years ago all fossil hominids are of the sapiens desing, while all those clearly older show the erectus pattern. Except for their large brains, Neandertals are of the ere…
Secular Trend in Emargination of the Japanese Patella, with Special Reference to the Skeletal Gracility of the Earliest Jomon People
The secular trend in emargination of the Japanese patella was studied on a total of 220 specimens ranging from the prehistoric Jomon period to the present age. There was found a significant decrease both in the incidence and in the relative size of the supero-lateral notch of the patella with the progress of civilization. It was suggested that the emarginate patella was due to a deficiency of bone, in relation to the development of the quadriceps…
Notes on the Flattened Tibia of the Earliest Jomon Juvenile from Kamikuroiwa, Japan
The tibia of a juvenile, aged 12 to 14 years, excavated from the rockshelter at Kamikuroiwa, Japan, dating in the middle of the Earliest stage of the Jomon period (ca. 6000 B. C.), exhibits a marked degree of platycnemia (cnemic index, 54.7). In comparison with the juvenile tibia belonging to the Late to Latest Jomon stages (ca. 2000 to 300 B. C.), it is suggested that the Earliest Jomon people growed and decayed slightly earlier than the Late-La…
Secondarily Buried Earliest Jomon Skeletons, Including the Hip Bone Pierced by a Bone Spear Tip
The human skeletal remains excavated at Rock Shelter of Kamikuroiwa, Ehime Prefecture, Japan, in August 1969 dated back to the middle of the Earliest stage of the Jomon period. The number of individuals estimated was seven. Three of them, two adult males and a child, were found buried secondarily in a small circular pit dug at the innermost recess of the rock shelter. The following was the form of the secondary burial observed: firstly, their sku…
The So-called Squatting Number of the Femur in Japanese
Observations on the lower ends of 378 femora from modern Japanese who were accustomed to squat both at rest and at work were made and compared with other published results.The average mean of the so-called squatting number by which the depth of the intercondylar fossa at the level of the intercondylar line was to be multiplied to give the greatest depth of the lower articular surface of the femur for Japanese was 3.23.It gave Japanese an intermed…
