A historic report describes measuring the body's electrical resistance via a reflected light method. Prof A C Jolly demonstrates how emotion may alter resistance, with a galvanometer linked to a salt pad and bridge. Some physicians debate adding this to hospital training and London doctors consider tests using local electricity.
Two Swiss researchers Doctor Anne Pieter and Hans Vogel announce success in synthesizing cane sugar from basic elements. They credit progress after earlier attempts by Emil Fischer and note cane sugar is made from glucose and fructose, previously not assembled from carbon and water.
Geneva researchers build on Fischer and Haworth Hudson work to link bodily electricity with glandular and mental states. Experiments using a salt pad and Wheatstone bridge show emotional stimuli alter light reflex position, suggesting potential diagnostic tests for sclerosis neuritis and nervous conditions.
The article explains how dried sea grass or zostera marina absorbs sound and acts as an insulator. It notes sea grass is non inflaming and insect free, aiding in house construction and upholstery. An experiment with a clock demonstrates its sound dampening capability. Tiles with perforated metal trays and felt like packing also absorb about seventy percent of noise.

Squeezing a rubber bulb in the ballet skirt squirts perfume from the knee nozzle.
A discussion explains that even tiny evaporated amounts reach the nose and that odor depends on molecular arrangement. The U S Bureau of Standards notes vanillin and methyl salicylate share elemental makeup but differ in atom order and odor. A decorative atomizer drawing shows a tasselled cushion device with a concealed reservoir fill opening.
Baron C Shiba of Japan perfected a high speed camera that captures twenty thousand frames per second. It records one second of movement in twenty minutes on screen to study bird flight for aviation insights. Ordinary film runs at sixteen frames per second revealing new details of bird lift and descent.
