ICCD speckle observations of binary stars. 11: Measurements during 1991-1993 from the Kitt Peak 4 M telescope
One-thousand one-hundred ninety-seven observations of 730 binary starsystems, observed by means of speckle interferometry with the 4 mtelescope on Kitt Peak, are presented. Included in these binary starsare new interferometric companions to five visual binaries. Thesemeasurements, made mostly during the period 1991 to 1993, comprise the11th installment of results stemming from our speckle program at the 4 mclass telescopes on Kitt Peak, Cerro Tololo, and Mauna Kea.

Mesures d'etoiles doubles faites a Nice, etoiles doubles nouvelles (24eme serie) decouvertes a Nice.
Table 1 gives 1182 measurements of 682 binaries observed with the 74 and50 cm refractors. Table 2 lists 26 new binaries discovered with the 50cm refractor.

New binary stars (18th series) discovered at Nice
The detection of 150 uncataloged binary systems using 50 cm and 74 cmrefractors at the Nice Observatory is reported. The list of newlydiscovered binaries is presented, including magnitudes, separation,probable periods, the 1900 right ascensions, and the types of the stars.
