1~217 caused to breathe anl atmosphere containing the vapour of Ni(CO)4.EXPERIMENT XYII.-A rabbit, weiglhing 1,090 grammes, was placed in a bell jar containing 24 litres of air.A small tube containing 0.6 (ubic ceitimetre of Ni(CO), was broken inside the jar, and the fluid evaporated very quickly.As 1 cubic centimetre of the liquid Ni(CO), at 170 C. contains 0.87146 grammie of CO, whieh at 0° and 760 millimetres yields *696.5 cubic centimetres of gas, 0.6 cubic centimetre would yield about 417.9 cubic centimetres of CO gas.As 1 molecule of Ni(CO), contains 4 molecules of CO, the animal breatlhed *an atmosplhere conitaining 0.432 per cent. of Ni(CO)1 gas.3.0 P.,i., animallpiaced in jar; 3.7, agitated muscular tremors;*urination; defiecation; :3.13, animal sitting upon hind legs; no paresis; vessels of ear full of brigbt red blood; :3.25, weak in movements, but Ino marked symptoIns; removed from jar; 3.26, temperature of mouth, 37.30 C.; :3.40, trembling aind weak in legs.The animal was found dead next morning, slhowing a lethal effect after breathinlg an atmosphere containing 0.432 per cent.for twenty-five minutes.
