Excerpt from page 133:
Eyes. – While nineteen individuals had dark brown eyes, one individual had black, one green-brown, and two gray-brown eyes. The sclera were bloodshot (14), yellow (3), clear (3), or yellow and bloodshot (2). The iris was homogenous in Nos. 4464 and 4472, rayed in No. 4471, and zoned in Nos. 4464 and 4473. Seven men (Nos. 4456, 4458, 4464, 4474, 4481, 4482, and 4484) had blue-ringed irises, possibly arcus senilis. No. 4467 had a dark rim around his iris, and Nos. 4477 and 4480 had Negroid eyes.
