(John), a native of Silecia in the 17th century, who practised physic at Leyden, and was remarkable for undertaking 16 languages. He supported an opinion, that the German and Persian languages were derived from the same origin.

ELLIQUATION, in chemistry, an operation by which a more fusible substance is separated from one that is less so, by means of a heat sufficiently intense to melt the former, but not the latter. Thus an alloy of copper and lead may be separated by a heat capable of melting the latter, but not the former.
