Acetarsol, an arsenical preparation, had no filaricidal effect on larvae and adults even when it was administered to dogs per os in such a large total dose as 500 mg. Copper glutaminate was found ineffective when injected subcutaneously or intravenously in a total dose of 3.75ml/kg. Filarial larvae and adults were not killed by sodium oxyantimonic gluconate which had been injected intravenously in such a large total dose as 350 mg Sb/kg. Bromsulfalein, Bayer 205, and phthalofyne were proved to be ineffective when administered intravenously in a total dose of 200, 300, and 1, 250mg/kg, respectively.

Pieces of beef and pork were examined for keeping quality when they were stored in air-tight polyethylene package or in bamboo-leaf wrappers. The results indicate that the meat on test had es sentially the same keeping quality, regardless of the kind of package and irrespective of the presence or absence of wrappers. Besides, some further problems on storage of meat were discussed.

A total of 558 cattle, including many Japanese oxen and some dairy cows, were examined for pathological changes of the abomasum, in the Sasayama Slaughterhouse during a period of 9 years from 1955 to 1963.
1. Principal lesions were erosion, ulcer, and atrophy of the mucous membrane. The former two affected 252 head (44.7%) and the latter 16 (14.1%).
2. Seasonal occurrence of erosion was observed in summer. It was the highest in June, the rate being 82.3%.
3. The number of foci of erosion was larger in the fundus-gland region than in the pyloric region. The. fact indicates that erosion was closely related with matallic foreign bodies ingested.
3. Erosive foci were a few in some cases and innumerable in others. They were round, oval, or irregular in shape, circumscribed, concave downward, and dark-red or reddish-brown in color. Some of them were 1 to 40 mm in diameter. Others were long tape-like or lineal, being 3 to 17 cm in length.

タンニン酸パマキン錠を用いて, 鶏Leucocytozoon病の発生予防, 治療試験を, 1962年7月7日より9月12日まで行ない次のような所見を得た.
1) タンニン酸パマキン錠を20～40mg雛に3日間連投与し, 5日間休んで3日間連投与を繰り返した場合, 野外自然感染をA群で8羽中5羽, B群で6羽中4羽血中のgametogonyの出現を阻止する成績を得た. これにたいし, 対照群は7羽中7羽に出現を認めた.
2) gametogony出現時の臨床症状は, タンニソ酸パマキン錠投与群は対照群に比べて採食, 飲水量, 元気など良好であった.
3) 生体重の測定を試験期間中行なったが, 感染時の雛の発育および回復は, タンニン酸パマキン錠投与群が対照群よりも生体重の動揺が少なくよい成績を得た.
4) フラゾリドン (Nf-180, 0.03%) を添加したB群は, 添加しなかったA群よりも発育が悪い成績であったが, 試験羽数が少ないので今後さらに試験を行なう必要がある.
5) タンニン酸パマキン錠を治療の目的で, 37日令のL病感染雛に100mg1回投与したが, 血中のgametogony, 臨床症状は全く変化を認めなかった.
6) 今回の発生予防試験では, タンニン酸パマキン錠の副作用を依然認めており, 今後投与間隔の延長または投与量の問題を究明しなければ実用に供することは困難であると思う.
