Single conductor and multiconducl-or electrical cables with wood bait pieces. A light to moderate growth of hydroids was present on the insulations, with some of the hydroids growing to about 3/4 Inch long. No detrimental effects on the materials were noted at the site of hydrold attachment. Laminated Plastics. The 1 x6x 1/8-inch laminated plastic materials made of epoxy, phenolic, and malamine resin filled with either cotton fabrics, paper, glass fabrics, or nylon fabrics were not damaged by biodeterioration or by the deep sea environment. The moisture absorbed by the plastics was determined by weighing each of the test specimens before and after exposure in the sea. The results are presented in Table 8. Glass. A considerable amount of hydrold growth was found adhering to the top and the bottom sides of the glass slides (Figure 36). When the growth was removed and the glass surface cleaned and examined under a microscope, the surface of the glass was smooth and no etching or frosting of the surface by micro- organisms was evident. 43
