48- Paralichthys albiguttus, 12 cm long, fully adapted to a very light gray background. This specimen continuously appeared somewhat darker than the background. Note that the three ocelli have almost entirely disappeared. 49- Individual (B)..., on black and white background (dots 0.5 mm. in diameter).... Dots of this size, no matter how numerous, had no effect except perhaps to cause the skin to become uniformly slightly grayer. 50- Individual (B) on black and white background (dots 1 mm in diameter)...after having been fully adapted to 1 cm. squares. These spots have no appreciable effect on the skin unless they are more numerous than they are in this background. 51- Individual (B) on black and white background (dots 1 mm. in diameter)....after having been fully adapted to dots 2 mm. in diameter. Note that the posterior ocellus is much darker than on white, but that the two anterior ones are not....
Paralichthys albiguttus, individual (B) on black and white background (dots 3 mm. in diameter).... 53- Individual (B), on black and white background (dots 3 mm. in diameter).... -54 Individual (B), on black and white background (dots 2 mm. in diameter)....after having been fully adapted to white. 55- Individual (B), on black and white background (dots 5 mm. in diameter).....
13-Paralichthys albiguttus, Individual (B) on a smooth white background continuously from July 23, 2 p.m., to July 25, 10 a.m. It was alternately on white and on black about equal time during the preceding seven days. The skin actually appeared much whiter and less mottled and the animal less conspicuous than the photograph indicates. This is partly due to the shadow in the background along the ventral side. In specimens kept continuously on white for two months the skin became much more uniformly white. 14- Individual (B) on black and white background (circles 5 mm. in diameter) from August 11, 12 m., to August 13, 1:30 p.m... 15- Individual (B) on black and white background 2 cm. squares from August 24, 11 a.m., to August 27, a.m., after having been adapted to white... 16- Individual (B) on black and white background (circles 5 mm. in diameter) from August 15, 10 a.,m., to August 16, 9 a.m. This photograph shows one of the most remarkable concealing patterns observed. The fish appeared to contain numerous holes.

Bliss No.15K Automatic Round Can Water Tester.--This machine receives the cans from the end soldering machine, automatically clamps and charges them with compressed air and carries them through the testing tank. The cans during submersion remain close to the surface and leakers are readily detected and removed. The machine handles cans from 2 to 5 inches in diameter by 2 to 6 inches in height, and operates at the rate of 120 cans a minute. We build a large machine, No. 16K, for gallon cans.
Bliss No.12 Automatic Double Seamer.--This machine will double seam round tins from 1 1/2 to 6 1/4 inches in diameter by 3/4 to 10 inches in height at the rate of 37 ends a minute. The operator need only place the can in position, depress the treadle, and the machine does the rest. It produces a tight and perfect seam and every seam is uniform because of an equal pressure.
Bliss No.253 Double End Flanging Machine.--This machine rapidly flanges both ends of can bodies (soldered or lock seamed) in preparation for double seaming tops and bottoms. A special patented device prevents the receding of the tail sotck during the operation, insuring univorm and even flanges. It will handle bodies 2 to 8 1/2 inches in diameter by 2 to 10 3/4 inches in height, and is easily adjusted for different sizes of cans.
Bliss No.15 Automatic Round Can Flanger.--An entirely automatic machine of the four chuck type, continuous in operation and positive in action. It produces a perfect and uniform flange. The movement of the chucks is comparatively slow and the bodies are flanged without danger of cracking the tin. It is arranged with automatic body feed and handles can bodies from 2 to 6 5/8 inches in diameter by 2 to 7 inches in height, at the rate of 100 to 150 a minute. The friction clutch with which it is provided gives instant control.
Swanson Can-Opener : a new and practical device invented by a practical canneryman. Will open any size, any diameter, any style sanitary can
Bliss No.12 Automatic Double Seamer.--This machine will double seam round tins from 1 1/2 to 6 1/4 inches in diameter by 3/4 to 10 inches in height at the rate of 37 ends a minute. The operator need only place the can in position, depress the treadle, and
31- Paralichthys albiguttus (F), 14 cm long, in large, shallow granite pan (variegated, dark blue and white).... Note the small white spots shown in irregular rows across the fish. 32- Individual (F) on black and white background (dots 2 mm. in diameter). The white spots in the irregular rows have become more conspicuous, but the pattern is essentially the same, although the spacial interrelationship of the light and dark areas in the background is very different.... 33- Individual (C).... in...granite pan...34- Individual (C) on black and white background (2 mm. squares).... Note that the patterns produced by these two very different backgrounds are essentially the same.
