Observations on 24 cases of Tonsillar Malignancies that were found during the Period of 8 years are made with review of literature.
Theas 4 cases are characterized by having early metastasis to Iymphodes of the neck.
Tonsillar cancer are almost squamous cell carcinoma, tonsillar sarcoma are nearly reticulum cell sarcome.
Tonsillar carcinoma have good prognosis by surgical treatment, but tonsillar sarcoma have a poor prognosis by surgical treatmen
Thearfore tonsillar sarcoma will perhaps have good prognosis by irradiation.

It has been reported that cancer origirating from the hard palate is rare among the neoplasms in the mouthc avity.
Recently we have experienced and reported two cases of the hard palate cancer, hick differed, foom each other, in the place of origin, in the histological finding and in the clinical course.
The first case was a woman of 62 years old, who under took the total extipation of the left maxilla (histologically adenocarcinoma) and has showed neither total relapse nor metastasis during nine months up to the present.
The second case was a 35 years old man, who suffered form the squamons cell carcinoma originating on the median line of the bony palate and showed at the firstexamination, massire metastasis to the neck lymphglands on both side the patient was treated with radiation therapy (X-ray) and Radium in rain and died after lung metastasis of the cancer.
We have described the clinical course of these two cases in detail and discussed by radiation therapy for the malignant neoplasms of the hardpalate origin radiatire lesions to periostal and bony tissues.

The authors encountered on a 19 years old man, who had a neurilemmoma occurred from the left border of the tongue. After the removal of this tumor, the patient was healed completely. Then clinical and histological findings of the neurilemmoma were discussed.

The report was made on 35 years old female who had Congenital Lateral Neck Cyst without Fistula.
In pathological findings of extirpated cyst, it seemed to be thyroid gland tissue and pardally to be carcinoma-like change.
We reported statistical study of congenital neck cyst in recent ten years.

The movements of the soft palate and the root of the tongue during production of speech sounds were observed with four cleft palate speakers using cineradiography with electronic image intensification. The results were compared with Umeno's previous investigations with normal subjects.
Incompetency of the nasopharyngeal sphincter and disturbances of time relationship between the movement of the vocal tract and tone production were the main abnormal findings observed in the cleft palate speakers. It was also noticeable that the highness of elevation of the soft palate varies according to speech sounds in different ways from the normal.

The intra-nasal, intra-oral and subglottic air pressures were measured during production of various Japanese speech sounds, andd these values of pressure were compared with the sonagrams of each sound in degree as well as in time relation.
A new electromanometer, in which the mechanical pressure is changed to the electrical energy with strain guage, was used in order to record delicate changes of the pressure corresponding to each component of speech sounds.
Both speech sound and air pressure were traced on the electrical oscillograph and simultaneously the former recorded with a tape-recorder to be analysed on the sonagram.
The results obtained are as follows.
[I] On the intra-nasal air pressure
1. The intra-nasal air pressure does not rise so markedly except during production of nasal syllables. The pressure begins to rise ca. 35-50msec. prior to the phonation and reaches its maximum value 7-13mm H₂O at the end of the nasal consonant and then it drops rapidly at the following vowel.
2. During phonation of some vowels such as “i” or “u”, a slight rise of the intranasal air pressure is occasionally observed.
[II] On the intra-oral air pressure
1. The intra-oral air pressure is not observed to rise during phonation vowels or nasal syllables.
2. The intra-oral air pressure begins to rise almost simultaneously with the utterance of voiced consonant syllables, i. e. with its proceeding wave. The maximum value (5-7mm H₂O) of the pressure is observed at the end of the voiced consonant wave in the fricative sounds and at the beginning in the plosive sounds.
3. The intra-oral air pressure begins to rise 60-80msec. prior to the phonation of the voiceless fricative consonant syllables and 170-210msec. prior to the plosives. The maximum value (7-9mm H₂O) of the pressure is observed at the point of 1/4 or 1/5 of the consonant wave in the fricative sounds and at the end in the plosive sounds.
4. The pressure drops rapidly at the following vowels in the both voiceless and voiced consonant syllables.
[III] On the subglottic air pressure
1. The subglottic air pressure rises during phonation of all speech sounds, and its maximum value is almost the same, showing the height of 30-50mm H₂O.
2. The subglottic air pressure begins to rise prior to the production of every speech sound. This phenomenons considered to show the “Kaiser's Effect”, and the latent period between onset of subglottic pressure and voice production varies according to speech sounds, i. e. it shows 170-190msec. in voiced vowels, 80-90msec. in nasals, 90-110msec. in voiced fricatives, 80-120 msec. in voiced plosives, 80-100msec. in voiceless fricatives and 160-190 msec.in voiceless plosive, sounds.
3. There is also a difference in the way of elevation of the subglottic air pressure among speech sounds. During phonation of vowels and voiced plosive consonant syllables, the curve of ascending subglottic pressure to be traced on oscillograph is more convex, on the contrary, is more concave in nasals and voiced fricative consonants. During phonation of voiceless consonant syllables the subglottic air pressure continues to rise to the production of following vowels, but in the course a transient slight drop is always observed. This drop of air pressure corresponds to production of the transitional part of consonant syllables and follows to the time when the intra-oral air pressure shows its maximum value.
