    Somatological measurements were conducted on a total of 182 male forestry workers rangings in age from the twenties to the fifties as selected from Yakushima islanders. Major results were as follows. 1. The mean value obtained for the maximum head length was 188.74mm, which is to be ranked in the lower category of Medium Type. The mean value for the maximum head breadth was 155.67mm which is to be ranked as Broad Type. The length-breadth index was 85.09 which belongs to Brachycephalic Type. 2. The mean value for the breadth of zygomatic arch was 146.08mm which belongs to Broad Type, and the mean value for the morphological facial height was 124.13mm which belongs to Medium High Type. The morphological facial index was 87.37 which is to be classified in Medium Type. However, the frequency of types showed that Medium Typs was 16.85%, Long Type was 28.80%, Extreme Short Type was 28.26% in all subjects. 3.

    The qualities of dental investment are specified and assured at the minimum by Japanese Industrial Standard, and manufactureres are obliged to describe the adequate and accurate instructions for proportioning and manipulating on each unit container : the water-powder ratio, the setting time, the setting expansion, the thermal expansion curve, etc. With reference to these instructions a proper mold for each casting alloy may be successfully prepared, if the very details of the instruction were kept. From the practical point of view, however, it is quite troublesome and nonproductive to keep to such instructions each time carefully. Of course, for the professional it is most desirable for these mixing conditions and other factors to have no effects on the properties of the set investment. But it is not the case. Thus the authors checked the factors, on some dental investment, and decided the ranking of the practical importance of them which should be carefully controled in mixing investments. The results obtained are as follows : 1) The first and the most important factor to be controled is the water-powder ratio, which has a marked effect on the setting time, the setting expansion and the thermal expansion for all the investments. Thus, the powder and the water to be mixed should be properly balanced in accordance with the maker's indication and not by the empirical intuition. 2) The second important factor is the room temperature, which has a great effect especially on the setting behavior. This factor might be difficult to be controled and so the temperature dependence of each investment should be well acquainted prior to the mixing. 3) The third factor is the spatulation time. This factor may be controled to the allowable extent empirically without time measurment. 4) Other factors such as the water temperature, the interaction of water-powder ratio with water temperature or with spatulation time have less but appreciable effects. 5) Each of the foregoing factors showed respectively nearly the same effect on all the investments used in this experiment.

    A total of 72 specimens of the male Japanese adult mandible was selected for the preparation of individual plaster mould to reproduce the negative contour of a more or less circular depression which separated the basal part of the frontal section from the alveolar border and which had been referred to by Virchow as incurvatio mandibulae anterior and by Klaatsch as impressio incisiva. The sagittal sections were made from each mould and visual observation on the general contour of the section was noted, and further, drawings were constructed from each section to serve for the subsequent measurement as shown in Fig. 1. The results were summarized as follows. 1) Visual observation on the profile of the depression showed that it resembled the profile of a half-cut egg standing lengthwise with its greater curved end directed upward (Fig. 2). This curvature was apparently smaller in mandibles from the younger subjects and greater in those from the old-aged. 2) The angle id, B, pg as measured on the drawings ranged from 140 in the minimum to 161 in the maximum with a mean value of 151.92 ± 0.59 as shown in Table 1 and 2. When the intersecting point between the vertical line passing B and the line connecting id and pg was calculated for its position by the formula (distancc id to B')/(distancn id to pg)×100 and designated as B', the percentage value of B' ranged from 25 in the minimum to 48 in the maximum with a mean value of 37.25 ± 0.67. The percent values of the angle id, B, pg as calculated within every groups of drawings having different B' values showed a trend similar to that obtained from the visual observation of the depression profiles.

    It is neccesarry to establish methods and technical procedures of dental cell culture before develop <in>___- <vitro>___- study of human jaw-tumor which might included many significant findings. Cultivations of the dental pulps and odontoblasts were preliminary done using human and mouse materials. Tissues for present experiments were maintained in the Rose mutipurpose culture chamber containing Eagle's medium (MEM) supplemented with 10% bovine serum. Following results were concluded : 1) Cells were appeared from the dental pulps of both human and mouse between 4 th to 7 th culture days. 2) The human pulp cells were seemed to show fibroblastic features though, the pulp cells of mouse were observed having rather different cellular features. 3) Growing cells appeared from human pulp were recognized with spore-like charactor which might be induced by pinocytic functions. 4) Human odontoblastic cells were observed from dentin portion at between 7th to 8 th culture days. 5) Those cells showed fibroblastic features at beginning of cultivation, then they were changed into more peculiar odontoblastic patterns.

    This is a report on the study made to compare and clarify splitting lines on lingua mucous proper layer of four mature mammals-rat, rabbit, cat and dog, as outlined below : A) Basic patterns of line systems common among the four are as follows : 1. Multiple arched lines and/or oblique lines systems that run from the central portion of the dorsum of the tongue toward both outer edges. 2. Multiple arched lines and/or oblique lines systems that run from both edges of the dorum toward the tip of the tongue. 3. Irregular lines that fill the central part of the dorsum and root of tongue. 4. A continuous line system that run along the frenum of the tongue (except that of the dog in which case this line is not seen.) B) Lines systems peculiar to each specy are as follws : 1. Rat. Lines systems that surround the torus linguae of the tongue ; the wave of arched lines rising from both edges, of which peaks are about to meet each other at the center ; and waves of chevrons projecting backward from the tip of the tongue. The group of lines that run almost the whole inferior surface of the tongue are simple oblique ones. 2. Rabbit. One or two continuous line systems that surronnd the torus linguae of the tongue and the arched lines group, and the concentric ellipse lines on the sublingual face. 3. Cat. Two groups of chevrons rising from both edges, opposite to each other at the root of the dorsum of the tongue ; the multiple parallel vertical lines that run along and near both edges of the tip of the tongue ; the horse-shoe like lines on the inferior surface ; and the group of irregular lines seen around the rim of the tip of the tongue. 4. Dog. The group of nervate lines on the dorsum and tip of tongue, and one continuous line that runs along the entire edge of the inferior surface of the tongus.

    Recently, I had an opportunity to encounter a 7 years old boy suffering from cleft of left prepalate and palate, bifid tongue associated with a thickened lingual frenum, hypertrophy of upper and lower gingiva, delaid eruption of permanent teeth, hyperterolism, deformity of nasal alar cartilarge, basilar kyphosis, digital anomalies consisting of brachyphalingia of fingers and toes and shortness of radius and ulna. Chromosomal analysis made by the peripheral leukocyte culture technic in the present patient showed 46/XY, with no visible abnormalties. Furthermore it was revealed that his parents were in consangunieous marriage cousinly. The author's opinion about the present case is that such a condition corresponds to a subtypical form of oral-facial-digital syndrome described by Papillon-Leage and Psaume in 1954.

    The term, Treacher Collins syndrome has been widely recognized as the condition which was indicated by E. Treacher Collins in 1900. First 2 cases reported by him showed symmetrical congenital notches in the outer part of each lower lids, palpebral fissures sloping downwards laterally (antimongoloid) and malar bone hypoplasia. The cases of congenital notches at the outer part of the lower lids were, however, already reported by G. A. Berry in 1889. In 1944, Franceschetti and Zwahlen who studied in detail this condition, recommended the term, dysostosis mandibulo-faciale. There after both have been used synonymously. We encountered December 6, 1967 a six-year-old girl with palpebral fissures sloping downwards laterally (antimongoloid), malar bone and maxillar hypoplasia, macrostomia and mental retardation. Our case seems to belong to the incomplete form of mandibulo-facial dysostosis (Treacher Collins syndrome).
