 Animal life is very abundant n some
 parts ot the world at great depths in ,Ae
 sea. This is illustrated by the fac, tha,
 during last summers explorations by the
 French steamer Talisman one haul of ,,s

 The Airs Plant Food Besides ai.fe. gen and oxygen, the air contains I. smaller proportion carbon;c ae,d, m. monia and certain nitrous compounds substances which are very important te vegetation. Late researches at the Trench observatory on the Pic du Midi, abou; , 500 feet above sea-level, show that ,he proportion of carbonic acid in the ait does not vay percep,ibly with the a,F. tude, as has hitherto been thought. ap1 that ammonia IS as completely difasea Tn the atmosphere as carbon.c acid. .Hy discharging of absorbing these .so gas. eous substance, the sea IS behcge' ' act as great regulator of he supply keeping their proportions Tn the air re- marNabiy constant and uniform through out the world although the Ia.:nt'sje. wl;hdrawn and added on ,he iana nlas. be ine"ssanily changing-l. is.is beer supposed that the nitrous eempo .nds afe produced by electric discharges wh.eh cause the chemical ucloa of he airs OK gen and nitrogen, and ,his view x confirmed by the fact that no .faees ai these compounds have been found q. the Pie du Midi above the heisn,s reached by tnunder-storms.
 Symbiosis - In inc anima. ard vece. table kingdoms are found two dls,ne, forms of fellowship in which dssimila. organisms live constantly together. n one form-ihat of parasitism-on ore of,he associated organisms lives at the eNpeuse of the other, as, for instance. the mls.le- toe on the aPpie-tree. In the ether form, the advantage of the compan!onship is as in the case oi the well scosn henmi. crab, one species of which picks up an empty shell for an abode and shares this and its food with a sea are none, which in return protects us hos; by means ot numerous long thread. charged with singing acid which Il shoots out on the slightes; alarm 3y exp riment a; Naples 1t has been p.oven that ,he compact between these two partners IS so close that one Is inaispens. able 10 the other. \ still more re.aark- lele illustration is drawn from the can. lie-na. tree of South America. which 'orrs an alliance with a species oi small black ant. 70 their mutual bene.i:.
