of the Western Islands of Scotland, about 25 miles long, and as much in breadth. It is in general rocky and barren, not producing a sufficient quantity of corn for the inhabitants; but a great number of cattle are annually exported, which with the fishings and a considerable quantity of kelp are the only articles of commerce. It is deeply indented with bays and creeks, forming in several parts good natural harbours. There are no villages except Tobermory, near the northern point of the island, where a fishing station has been lately erected. The island was originally part of the dominions of the Lords of the Isles; but in after-times it became part of the possessions of the ancient and valiant family of Macleans, who still retain one-half. The other is the litigated property of the duke of Argyle, whose ancestor possessed himself of it in 1674, on account of a debt; but after the courts of law had made an adjudication in his favour, he was obliged to support their decree by force of arms. The ruins of several ancient castles are seen on this island.

Muller or Regiomontanus (John), a celebrated astronomer of the 15th century, was born at Koningshoven in Franconia in 1436, and acquired great reputation by publishing an abridgment of Ptolemy's Almagest, which had been begun by Paracelsus. He went to Rome to perfect himself in the Greek tongue, and to see the Cardinal Baffarion; but finding some faults in the Latin translations of George de Trebizond, that translator's son assassinated him in a second journey he made to Rome in 1476, where Pope Sextus IV. had provided for him the archbishopric of Ratibon, and had sent for him to reform the calendar. Others say that he died of the plague.

Muller (John), a noted engraver, who flourished about the year 1600, and had been bred under Henry Goltzius, whose style he closely imitated. The facility with which he handled the graver (for he worked with that instrument only) cannot be sufficiently expressed; his works must be seen, to convey a proper idea of it to the mind. His engravings are valuable, as productions of a very extraordinary nature; exclusive of which they have a prodigious share of merit. Among his most estimable performances, may be mentioned, 1. The hand writing on the wall, a middling-sized plate lengthwise, from his own composition. 2. The adoration of the wise men, the same, from the same. Fine impressions of both these prints are very rare. 3. The resurrection of Lazarus, a large plate lengthwise, from Abraham Bloemart. He engraved also several much esteemed portraits.
