The purpose of this study was to find the response of the teleost's brain toward chemical stimuli.In carrying out the series of experiments, four species of teleost fishes were selected as working materials. They were Carassius auratus, Ophiocephalus argus, Monopterus javanensis and Hypophthalmichthys nobilis.The chemical agents for the experiments were selected as follows: Janus green, methylene blue, neutral red and crystal violet for staining purpose, i. e. for primary oxidation (Child' 47), in which...

The purpose of this study was to find the response of the teleost's brain toward chemical stimuli.In carrying out the series of experiments, four species of teleost fishes were selected as working materials. They were Carassius auratus, Ophiocephalus argus, Monopterus javanensis and Hypophthalmichthys nobilis.The chemical agents for the experiments were selected as follows: Janus green, methylene blue, neutral red and crystal violet for staining purpose, i. e. for primary oxidation (Child' 47), in which the specimens were examined with the results recorded before reduction process set in; and in addition potassuim permanganate was used for complete oxidation-reduction purpose. The concentrations of the former agents in Ringer's solution and the latter in distilled water were experimentally determined, and are given in Table 1-4.In all cases of the stain experiments, the metabolic rates of the nosebrain (including only the olfactory bulbs and primitive endbrain in the present case) are higher than any other division, and that of the cerebellum, the balancing brain, comes out to be the next, being higher than all the other parts of the organ (with the exception of Carassius). The midbrain (part of the eyebrain) is less responsive than the cerebellum; and the medulla oblongata, without the facial and vagal lobes (brain centers for taste buds) and with its anterior regions (the earbrain) overshadowed largely by the cerebellum or only with little parts visible from above; i. e., the skinbrain, is, on the average, least responsive of allIn Carassius, the vagal lobes showed somewhat greater sensitivity than the cerebellum, and in Hypophthalmichthys they were less so than the facial lobes, which in turn almost matched up with the cerebellum. As a whole, it may be said that the olfactory lobes and primitive endbrain are most responsive and the midbrain and medulla oblongata least so, the cerebellum somewhat between them, while the facial and vagal lobes vary in their responses to these stains, but they fall between the endbrain and the medulla. If the records of both these lobes were removed from the curves on Carassius and Hypophthalmichthys, (Chart V (A)-(D)), these four curves would have a much closer resemblance in the general tendency of responses among themselves; i. e., the centers of greatest activities are located in the nosebrain, there is a considerable dropping in the eyebrain, while the cerebellum, the balancing brain, shows a great deal of rise in responsiveness, though it does not go so high as either the olfactory lobes or the primitive endbrain, and finally the medulla oblongata, the skinbrain, shows least responsiveness to the stains.The results of the oxidation-reduction process (Chart VI (A)-(D)) show more or less a general resemblance to those o?the stain experiments, but there are some differences, which should be noted. In the case of Carassius the primitive endbrain falls in its functional features a great deal below the olfactory lobes and is now even lower than the cerebellum, and the vagal lobes are about on the same level with the midbrain, while in the case of Monoptenis the cerebellum is the most active division of the brain and the medulla oblongata is similar to the midbrain. In general, it is reasonable to assume that the physiological gradients in the brains of Carassius and Hypophthalmichlhys are similar to each other, as they are of the same family, and those of Ophiocephalus and Monopterus are likewise, though they are of different families. In spite of some deviations these brains in both stain and oxidation-reduction experimentes show a general trend of similarity in their responses.It is concluded that the sensitivities of the brain surface to these chemicals are in direct proportion to its functional activities and in reverse proportion to their histogenetic age. Besides these factors, the polarity of the organ and the size of its division also have a significant bearings on the physiological gradient, but the latter should be considered together with the organization and developmental st

This paper presents the information of the effect, measured with a tele-strain-meter, of work material, feed, cutting speed, depth of cut, number of teeth and helix angle etc. On the cutting torque at a high speed bobbing machine. An empirical torque formula for gears of diametral pitch 8 was obtained. Contrast of empirical torque formulas for carbide hobs and HSS hobs shows that they are basically similar. Experiment indicates that the hobbing torque decreases slightly as the cutting speed increases.
