A galaxy is a massive, gravitationally bound system that consists of stars and stellar remnants interspersed with a medium of gas, dust, and dark matter.
A nebula is an interstellar cloud of dust, hydrogen, helium and other gases.
However, in some older Astronomy literature, all "fuzzy objects" were called nebula, even if they were technically galaxies. This is because scientists had not yet established that galaxies were, in fact, objects outside the Milky Way.
They were presumed to be among the local gas & dust objects in our own galaxy. Edwin Hubble made the essential determination that some "nebulae" were considerably further away than other objects in the milky way and were, in fact, separate galaxies.
