In the early part of 1873, and for some time afterward, the system invented by Joseph Stearns was the duplex in practical use. In April of that year, however, Edison took up the study of the subject and filed two applications for patents.
One finds these in various combinations or as individual motives on the furniture of the Louis. Shows the red-tiled entrance hall of a duplex apartment in New York. The backgrounds for these mounts were the woods finely inlaid with ivory shell and brass in the style of the Italian Renaissance. Oriental lacquer and painted furniture, at that time heavily gilded.
Duplex telegraphy, or the sending of two separate messages in opposite directions at the same time over one line was known and practiced previous to this time, but quadruplex telegraphy, or the simultaneous sending of four separate messages, two in each direction, over a single line had not been successfully accomplished, although it had been the subject of many an inventor's dream and the object of anxious efforts for many long years.
Waife's character with the clemency due to human nature, but with the caution required by the interests of society, permit him to resume a "duplex course," sanctioned by ancient precedent, but not commended to modern imitation.
The Hopi director of the dances was Mootchka, whose costume was as astoundingly frightful as he could possibly make it.

Struthers reports two cases in which there were two cavities to the stomach.
High in the air, another signal wailed up and down a peculiar scale of sound and the mighty host of vessels formed smoothly into symmetrical groups of seven. Each group then moved with mathematical precision into its allotted position in a complex geometrical formation a gigantic, seven-ribbed, duplex cone in space.
Onward and upward flashed the gigantic duplex cone, its entire whirling mass laced and latticed together into one mammoth unit by green tractor beams and red pressors. These tension and compression members, of unheard-of power, made of the whole fleet of three hundred forty-three fortresses a single stupendous structure a structure with all the strength and symmetry of a cantilever truss!
