Ashes of composite samples of canned sockeye, pink and blueback salmon and canned pilchard were analyzed for Ca, Mg, Na, Ka P. Cl, S and traces of Cu and Mn. Comparison of the relative amounts of these elements with their concentration in sea water indicates selective absorption of Ca and K over Mg and Na respectively. The presence of Cu and Mn in trades is important for dietetic purposes.

Determinations of the Ca, Mg, Na, K, P and Cl content were made and the ratios of calcium, magnesium and phosphorus oxides suggest the presence of calcium and magnesium metaphosphates in the ash of the flesh, calcium metaphosphate in that from the skin and tribasic calcium orthophosphate in that from the bone.

Samples of canned coho (blueback) salmon (Oncorhynchiis kisutch), from fish caught each month of the fishing season (May-September) in a limited area on the coast of British Columbia, were subjected to analysis from which nutritive values were determined by the calculation of calorific values. The average percentages of constituents in composite samples of the entire contents were: water, 72.8; fat, 4.50; protein, 19.9; sodium chloride-free ash, 1.37; sodium chloride, 1.13; calorific value per pound of contents, 562. Percentages of fat, protein, sodium chloride-free minerals, and consequently the food value, reached a maximum in cans containing fish caught in mid-July.

Proximate Analyses

Proximate analyses of samples of canned pilchard from fish caught early and late in the season in one vicinity on the west coast of Vancouver island are tabulated. The average calorific value per pound of content was 747 and 1074 Calories, respectively. The percentage of fat (18.5) in the late-caught fish was almost twice as great as that in the early-caught fish. Separate proximate analyses of the flesh, skin, and bone disclosed significant changes in the percentages of fat, protein, and minerals in these components between the beginning and end of the season.

Proximate Analyses

Proximate analyses were made at bi-monthly intervals during 1933–34 on samples of Ostrea lurida, O. virginica, and O. gigas grown under identical conditions in the strait of Georgia. The proportions of glycogen and protein are shown to be approximately reciprocal and the greatest variation to occur during the summer. The energy content varies slightly, attaining a maximum in late fall and early winter, O. gigas having the highest and O. lurida the lowest values.

Composite Samples

The proximate compositions and calculated calorific values of individual and composite samples of canned sockeye (Oncorhynchus nerka) and pink (O. gorbuscha) salmon from fish caught in several localities on the British Columbia coast are compared. The resulting data are also presented in such a way as to allow comparison of the composition and energy content of the various constituents in the can, some of which are frequently discarded in the utilization of canned salmon. The average percentages of the total oil, protein, salt (sodium chloride)-free minerals, and Calories contributed by the different constituents in the samples were respectively: flesh—(sockeye) 62, (pink) 72; 85, 81; 55, 54; 73, 78; skin—(sockeye) 11.2, (pink) 15.3; 3.6, 4.3; 9.8, 6.7; 7.7, 9.0; free aqueous liquor—(sockeye) 0, (pink) 0; 11, 14; 5, 7; 4, 8; free oil—(oil) 26, 10; (Calories) 15, 4; bone—(salt-free minerals) 30.2, 32.6. Corresponding average percentage compositions of composite samples of entire contents were: water—(sockeye) 68.6, (pink) 71.5; oil—8.82, 6.75; protein—20.2, 19.3; salt-free minerals—1.57, 1.57. The average energy contents were (sockeye) 749, (pink) 644 Calories per pound. Comparison with published analyses of canned sockeye and pink salmon from Alaska and Washington indicated that more extensive and detailed sampling will be necessary before conclusions can be drawn regarding the comparative compositions and food values of canned British Columbia salmons, and the relation of these values to those of salmon caught to the north and south.

The total oil in samples of canned British Columbia sockeye (Oncorhynchus nerka) and pink (O. gorbuscha) salmon, each from three different localities, contained respectively 50, 67, 67 and 50, 67, 67 international units of vitamin D per gram, equivalent to average contents of 1700 and 880 international units in the oil per pound of contents for the sockeye and pink samples respectively. The oil in the cans of sockeye salmon from two of the localities contained approximately 2.5 and 2.0 A.D.M.A. units of vitamin A per gram respectively. A composite sample of the oil in all the cans of pink salmon contained no appreciable amount of vitamin A. Several physical and chemical characteristics of the oil samples are given.

In a letter to Professor Tait, dated Mentone, 14th April 1882, Mr. Aitken says :—Since coming here this time, I have tested the sea with the polariscope and with the spectroscope. With an instrument by Hoffman, which gives coloured bands with polarized light, I have been able to detect small, but decided indications of polarization in the light internally reflected by the water, the surface reflection being, of course, cut off when the observation was made. At present I think the polarization is due to regular reflection from the polished surfaces of some of the particles, which are seen to glance brightly in concentrated sunlight.I have also detected an absorption band in the green of the spectrum of the light internally reflected by the Mediterranean water. This band is much more distinct in water where there are but few reflecting particles, and the light undergoes a great amount of selective absorption.

Influence of humid aging on tensile properties of two polymeric composites was studied. The purpose of the study was to evaluate the suitability of the materials for a naval helicopter external fuel tank. Due to the application, the humid environment was kerosene and saline solution to evaluate the sea water effect on the composite tensile strength. The composite samples were immersed in kerosene for 168 hours, respective 1752 hours and in saline solution for 168 hours. Tensile tests were performed after the immersion. The composite sample tensile tests showed that kerosene and saline solution had no influence on the elastic modulus of the materials, but it was observed a slight improvement of the tensile strength of the two polymeric composites.
