an artificial lake some twenty miles long by a dam across the valley at
or near a point where the proposed canal strikes it, a few miles from
Colon, such as was advocated by C.D. Ward in 1879." The site referred
to was Gatun, and this was written in 1880, when the sea-level project
had full sway.

So that it is going entirely too far to say that all naval commanders
and commercial masters are in favor of the sea-level project. Admiral
Walker himself, as president of the former Isthmian Commission, and as
president of the Nicaraguan Board, favored a lock canal. Eminent army
engineers, like Abbot, Hains, Ernst, and others, favor the lock project.
It requires no very extensive knowledge of navigation to make it clear
that passing through a waterway which fora depth of 19 cm with water containing milk and maintained at 25 ± 2°C. The pool was conceptually divided into four equal quadrants. An escape platform, 11 cm in diameter and 18 cm high, was located at a fixed position in the one quadrant and submerged 1 cm below the water surface.

The mice were pretreated with saline or WGOS for three days. On Day 4, the acquisition phase began, which consisted of five training days (Days 4--8 of the timeline are coincident with training Days 1--5) with three consecutive trials per day to find the platform. When a mouse reached the platform within 80 s, it was allowed to stay on the platform for 20 s until the start of the next trial. If a mouse did not reach the platform within 80 s, it was
