to Elegia, a city of that kingdom, where a Roman army, under the command 

 of Severianus, the prefect of Cappadocia, was at that time posted. This formi- 

 dable body he immediately attacked, and so entirely defeated it, that scarcely a 

 single Roman found means to escape. So complete a victory as this must of 

 course have put Vologeses in possession of the greater part of Armenia, and par- 

 ticularly of the city of Elegia. After so important a coiKjuest, the Parthian mo- 

 narch may naturally enough be supposed to have caused these medals to have 

 been struck, and that in the town of Elegia. And that this was really the case, 

 some will perhaps allow deducible from the monogram presented to our view on 

 one of these coins. Nay, that he derived the name, or surname, Peroz, or Pe- 

 rozes, itself from a successful expedition he undertook against the Romans, we 

 learn from Moses Chorenensis, the Armenian historian. " At which time, says 

 this writer, after the death of Titus the II. king of the Romans, called Antoninus 

 Augustus, Peroz, or Perozes, king of the Persians, (Parthians) made an irrup- 

 tion into the Roman empire ; whence he deduced the name Perozes, which sig- 

 nifies the Conqueror, or the Victor, having before been denominated Vologesus, 

 according to the Greeks, but by what name he went among the Persians I have 

 not yet been able to learn." Which passage seems not only to point at the de- 

 feat of Lucius Attidus in Syria, but likewise at the terrible overthrow given the 

 Romans in Armenia, soon after Marcus Aurelius and Lucius Verus ascended the 

 imperial throne, Mr. S. adds, that the Arabic Firilz and the Persic or Armenian 

 Peros agree entirely in signification, if they may not be considered as absolutely 

 the same word : that a Persian king, named FirCiz by the Arabs, is called Perozes 

 (n«o^ric) by Agathias ; and that Moses Chorenensis and one, at least, of the 

 medals here described, mutually strengthen and s upport each other. 



XXXFIII. A Successful Operation for the Hydrops Pectoru. By William 

 Moreland, Surgeon, at Greenwich, p. 302. 



As few instances are to be met with in chirurgical writers, of the successful 

 opening of the thorax in the dropsy of the breast ; the following person's case, 

 who was preserved by it in the most imminent danger of death, may encourage 

 others under similar circumstances to perform the operation, which has hitherto 

 been very rarely attempted. 



Anne Harmsworth of Croom's Hill, Greenwich, of a thin, hectic habit of 

 body, and subject to defiuxions on the breast, about the latter end of the year 

 1760, complained of a smart, shooting pain in her right side, which somewhat 

 affected her breast. Her evacuations by stool and urine were by no means de- 

 ficient, nor was there any remarkable appearance on the part aftected. A blister 

 was applied, and oily medicines given, which relieved her in a few days, yet not 

 so entirely but that she had returns of the pain at different times, though not
