TLDR
The conductivity bridge derives its bridge source from a self-contained vacuum tube oscillator adjusted to approximately 1,000 cycles as mentioned in this paper, which operates directly from the A.C. power source.Abstract:
The new Conductivity Bridge derives its bridge source. voltage from a self-contained vacuum tube oscilltor adjusted to approximately 1,000 cycles. Voltage for the amplifier and null indicator tubes is provided by a.builtin D.C. power supply which operates directly from the A.C. power source. 9-324 Conductivity Bridge, without Conductivity Cell, for use with 110 volts 5060 cycle A.C. 9-351.Cosi~uCvity Cell, for use with Conductivity Bridge, constant 0.8, $20.00read more

The multifunctional choroid.

TL;DR: It seems that the thickening of the choroid may be mechanistically linked to the scleral synthesis of macromolecules, and thus may play an important role in the homeostatic control of eye growth, and, consequently, in the etiology of myopia and hyperopia.

A Predator’s View of Animal Color Patterns
TL;DR: In this paper, the authors explore the factors that determine color patterns under various specific conditions and show that the actual pattern evolved in a particular place represents a compromise between factors which favor crypsis and those which favor conspicuous color patterns.
Journal ArticleDOI
Amniote phylogeny and the importance of fossils
TL;DR: The importance of the critical fossils seems to reside in their relative primitive‐ness, and the simplest explanation for their more conservative nature is that they have had less time to evolve.

Animal colour vision — behavioural tests and physiological concepts
TL;DR: An overview of the methods used to study animal colour vision is given, and how quantitative modelling can suggest how photoreceptor signals are combined and compared to allow for the discrimination of biologically relevant stimuli is discussed.
