EMULSION 



Empyema is a serious condition, 

 and if left untreated is likely to 

 prove fatal. In mild cases it may 

 be sufficient to draw off the pus 

 by aspiration, but generally it is 

 necessary to secure thorough 

 drainage of the pleural cavity by 

 making an opening between the 

 ribs or removing a portion of a rib 

 so that a large drainage tube can 

 be inserted. This causes collapse 

 of the lung on the affected side, 

 but if the operation has been per- 

 formed early there is a good pros- 

 pect of the lung re-expanding after 

 the discharge has ceased and the 

 wound has healed. 



Ems. River of Germany. It 

 rises in Westphalia, in the Teuto- 

 burger Wald, and flows mainly 

 in a N. direction through 

 Westphalia and Hanover to the 

 Dollart, an opening of the North 

 Sea. Its length is about 210 m., 

 and its chief tributaries are the 

 Aa, Haase, Hessel, and Leda. It 

 has been canalised as part of the 

 system of German waterways. 

 (See Dortmund-Ems canal.) Em- 

 den is at its mouth. On Oct. 6, 

 1914, the British submarine E 9 

 torpedoed and sank the German 

 destroyer S 126 off the Ems river. 



Ems. Town and watering- 

 place of Prussia, Germany. It 

 stands on the Lahn, in the prov. 

 of Hesse-Nassau, 11 m. from Cob- 

 lenz. It lies on both sidesof theriver, 

 and is in three parts Bad Ems, 

 where the waters are ; Spiess Ems, 

 and Dorf Ems, the original village. 

 There are some mines hear by, but 

 the town is chiefly known for its 

 waters, these and the beautiful 

 scenery attracting many visitors. 

 For them there are many hotels 

 and places of amusement of all 

 kinds, including the Kursaal in 

 extensive gardens and a theatre. 

 The royal Kurhaus, where many 

 of the springs and baths are, and 

 the new bathhouse, have every 

 comfort for those taking the waters. 

 There is a wire rope rly. to the 

 summit of the Malberg, one of the 

 picturesque hills in the neighbour- 

 hood, and steamers on the Lahn. 

 Before the Great War there was an 

 English church here. The congress 

 of Ems hi 1766 drew up the 

 Punctation of Ems, a protest 

 against the interference of the 

 pope in the affairs of the church 

 in Germany. Pop. 6,800. 



Ems Telegram. Message pub- 

 lished by Bismarck in 1870 which 

 was the immediate cause of the 

 Franco -Prussian War. France 

 had just succeeded in obtaining 

 the withdrawal of Leopold of 

 Hohenzollern as a candidate for 

 the throne of Spain, but put for- 

 ward a further demand. On 



July 13, 1870, Benedetti, the 

 French ambassador, interviewed 

 King William I, who was staying 

 at Ems, and requested a promise 

 that he would not allow the can- 

 didature to be renewed. The king 

 refused, and later in the day de- 

 clined to reopen the discussion. 

 To Bismarck at Berlin he sent an 

 account of the proceedings, and 

 this was the Ems telegram. 



Bismarck thereupon published 

 the telegram with certain altera- 

 tions, especially in that part of the 

 message in which the king informed 

 Benedetti that he could not discuss 

 the matter further. These made it 

 appear that instead of this being 

 merely a courteous refusal to reopen 

 the matter, it was a dismissal of the 

 ambassador from his presence. 

 Thus it was treated by France as a 

 casus belli. The vital sentence was 

 " His majesty refused to receive 

 the French ambassador, sending 

 word that he had nothing more to 

 communicate. " 



Emsworth. Seaport of Hamp- 

 shire, England. It stands at the 

 mouth of the Ems, a small stream. 

 With a station on the L.B. & S.C. 

 Rly., it is 76 m. from London and 9 

 from Portsmouth. The port has a 

 coasting trade and oyster beds. 

 Pop. 2,200. 



Emu (Port, ema, ostrich) (Dro- 

 maeus novae - hollandiae). Large 

 bird belonging to the division Rati- 

 tae. It is found only in Australia 

 and certain neighbouring islands. 

 The second largest bird now 

 living, it is only exceeded in size 

 by the ostrich, which it some- 

 what resembles in general build. 

 But the wings of the emu are more 

 rudimentary, and the bird depends 

 entirely on its swiftness as a runner 

 to escape its foes. The slender 

 feathers are brown, mottled with 

 grey, but the younger birds bear 

 longitudinalstripesof lightercolour. 

 Emus are rare except in the wilder 

 parts of the country, where they 

 live in small flocks and feed chiefly 



upon small fruits. Although not 

 web-footed, they swim well, and 

 take to the water readily. They 

 are hunted with dogs, and when 

 brought to bay can deliver serious 

 kicks. These birds are easily 

 domesticated, and breed readily in 

 captivity. The male, which i.s 

 smaller in size than the female, in- 

 cubates the eggs, which are green. 

 Emulsin (Lat. emulsus, milked 

 out) OR SYNAPTASE. Unorganized 

 ferment (enzyme) present in al- 

 monds and mustard seeds. The 

 action of emulsin on the amyg- 

 dalin also present in almonds pVo- 

 duces essential oil of almonds in 

 the process of manufacturing the 

 expressed oil. Emulsin may be

Emulsion. In photography, a 

 mixture containing the silver com- 

 pounds, sensitive to light, used in 

 the manufacture of photographic 

 plates and print- 

 | ing papers. Gela- 

 i tin emulsions, by 

 far the most com- 

 monly used, are 

 made by forming 

 the silver com- 

 pounds in a hot 

 solution of gela- 

 tin, which is al- 

 lowed to set to a 

 jelly, shredded 

 and washed, and 

 re-melted for 

 coating on plates 

 or paper, on 

 which it rapidly 

 sets. In collodion 

 emulsions, the
