    As has been previously reported by some students, Meretrix meretrtx tusoria has the peculiar habit of moving by means of string-like mucous excreted from the posterior region of the clam. This method of locomotion was found to be common during late spring and autumn. In the course of their histological studies, the present writers discovered conspicuous mucous tissue in this posterior region, which they believe may be correlated with this peculiar method of locomotion. This mucous tissue lies between the root of the siphons and the black line extending along the posterior palliat margins on the inner wall of the mantle surrounding the siphons, as shown in Fig. 1 & 4.
    For fixation of this tissue, Susa and Gilson solutions gave good results, while Bouin's solution caused great swelling followed by rupture. This mucous tissue was stained with Mucicarmine and Haematoxylin. The mucous cells were very tall, reaching a length of 0.35mm in clams 30mm in length (Fig. 2). Similar mucous tissue was not found in other clams such as Venerupis semidecussata (Fig. 3), Dosinia japonica, Mactra sulcataria and Mactra veneri formis which do not have this mucous-string method of locomotion.

    The results of the investigation carried out by the present author on the behavior of the spawning pollack schools by means of Fish-Detector and other various fishing implements are summarized as follows: -
    (1) Schools of spawning migration are found distributed in various shapes of band, cloud, and nimbus.
    (2) The depth of migration is not decided by temperature, depth, and topography of sea-bottom: it is distributed over very wide limit.
    (3) Sexual segregation is found to exist, males inhabit upper layer and the other lower one.
    (4) Immature groups come to migration together with spawning groups, but they are separated from the latter staying in waters shallower than that in which the spawner inhabit.

    In the present paper we report on our study on the cooperative action of salting and dehydration in fish muscle with reference to the preservation.
    Through a result of our scant experiments, we have found that salting and dehydration seemed to have some interaction in prevention against putrefaction of fish muscle. And it seems to us that the increase of the preservative effect of salting in combination with dehydration is constant irrespective of the concentration of salt in the meat. This would be suggested that the preservative action of salting merely was physical properties atributable to prevent the attraction of water by bacteria.

    In the present work, the authors have compared the characteristics of oxidized acids isolated from various fish oils having previously been subjected to autoxidation on the one hand, and measured the color intensities exibited by the alcohol-ether (I:2) solution, which had deen prepared by dissolving the oils added with different amounts of ammonia to its definite quantity on the other.
    The results of these experiments suggest that oxidized acid in general does not contain nitrogen as its molecular constituent. It seems likely that the function of the ammonia partaking in the discoloration of autoxidized fish oil is not to produce ammonium compounds with the oil; but the base behaves mearly as a catalyst.
    A number of substances apparently different from ammonia, whether inorganic or organic, were also found to play a catalytic action in the discoloration of autoxidized fish oil.

    Inquiring into the problem what substance in autoxidized oil does correspond to the precursor of oxidized acid, the authors have arrived at the following conclusions:
    1) The substance capable of forming the skeletal portion in the. net-work of Linoxyn gel is the prccursor under question.
    2) So-called linoxic acid isolated from Linoxyn may he identical with Fahrion's oxidized acid.

    In the previous paper* we have established that the nutritive value of highly unsaturated fatty acids is not much lower than that of oleic acid, and that long-believed toxicity of highly unsaturated acids is not produced by the acids themselves but actually by formation of autoxidized matters.
    The observation led us to an assumption that natural unsaturated fatty cids around C18, even if different in the autoxidation degree, would always become less nutritious by some autoxidation.
    The assumption was confirmed by examining the toxic effect on rats of the autoxidized product which was prepared from the ethyl ester of liquid acids of linseed oil, as the rats were all died in a few days after the feeding.
    On the basis of these findings our efforts have been extended to throwing light on the structure of the toxic product of the above description. The methods used for and the result obtained from the present test are as follows:
    (1) The autoxidized products were prepared by leaving the original ethyl ester of liquid acids of linseed oil, about 3mm. deep in basin, open to atmospheric oxygen under 30°C, 50 hours.
    (2) As shown in Table 1, the autoxidized products are fractionated by urea adduct formation, and the nutritive or retarding effects of each fractions are examined.
    (3) Fraction 1 separated from the autoxidized products (consist mainly of un-autoxidized esters) does not give any retarding actions to the rats, however, fraction 2 and 3 which do not form urea adducts show the toxic effects on the animals (Table 5). From these results it is apparent that aldehydes have no harmful effect upon the rats.
    (4) On the other hand, , polymerized highly unsaturated fatty acids which contain small proportion of peroxide show the nutritive effects to the rats (Table 6) and no retarding effects are noticed.
    (5) Judging from these results, the toxic effects which yield from the autoxidized acids should certainly be attributable mainly to production of peroxide-structure.
    In oder to prove this assumption, we liberated the peroxide of autoxidized products by Lea's peroxide-determination method. 11) In consequence, peroxide liberated products became “not-toxic” (Table7).
    On the basis of this result we have come to conclusion that the most toxic structure in autoxidized unsaturated fatty acids is peroxide which has been produced at the beginning of autoxidatron.

    The authors report here the result of examination obtained with several antioxidants in the application to some cured fish, the availability of which to marine products, despite their being expected of great promise, has yet scarcely been presented.
    They used B. H. A. (Butylated hydroxyanisol), B. H. A." (B. H. A. +Synergist), N. D. G. A. (Nordihydroguaiaretic acid), N. D. G. A." (N. D. G. A. +Synergist), E. P. (Ethyl protocatechuate), V. C (Vitamin C), and P. L. (Pix liquids) in the form of 0.005%, 0.010%, 0.025%, and 0.050% solutions, respectively, which were prepared in 12% NaCl solution.
    Defrozen samples of saury were splitted, salted and used for test. After salting for 16 hours in the curing solutions above mentioned, they were dried in the daylight, wrapped with paper, and stored at room temperture.
    The test was done organoleptically as well as scientifically about the improving and depressing effects of these antioxidants ; and also the conditions of their “marginal use ” were determined for the future investigation.

    In this work, the authors compare these antioxidants each other, which have been tested in the preceding work regarding their efficacy at the “marginal use” as defined there.
    B. H. A. was found to be most recommendable in the case of salted and dried saury. B. H. A.", N. D. G. A., N. D. G. A.", and E. P. were also effective but tended to be accompanied by red or brown colour development. V. C and P. L. proved to be but of little efficacy.

    This time it is measured the actual permeation of B. H. A. in fish, the efficacy of which has been confirmed in the preceding work. The results are described of the experiments carried out along the following procedures:
    1. Soaking the fish in fresh water containing B. H. A.
    2. Soaking the fish in suturated salt solution containing B.H.A.
    3. Salting the fish with dry salt added with B. H. A.
    4. Drying the fish after boiling in salt solution containing B. H. A.
