268 On the Vblalilily and Injlammabilily 



Cross-examined. — He did not think that old oil would give 

 gas at 460. He did not know whether the oftener oil was heated 

 the more inflammable it became. 



Mr. R. Henley agreed with the last witness as to his experi- 

 ments with oil and sugar, and was of opinion that the new pro- 

 cess was superior to the old. 



H. Coxwell, Esq., secretary to the committee of chemistry in 

 the Society of Arts, had made experiments on the relative com- 

 bustibility of oil and sugar. He was present at those made by 

 Mr. oooper, and agreed altogether in the account the other 

 scientific gentlemen had given. The new process was, he thought, 

 infinitely less hazardous than the old one. He thought there 

 was no sort of danger in boiling the oil. 



Thomas Gill, Esq., chairman to the committee of mechanism 

 in the Society of Arts, also witnessed the experiments of Mr. 

 Cooper, and entirely coincided in opinion with him. 



The Chief Justice here observed, that it was useless to call 

 any more witnesses to those facts. They had heard the evidence 

 of Mr. Accum, Mr. Allen, Mr. Cooper, and several other gentle- 

 men well versed in science and mechanics ; and to call others to 

 the same points, though it might swell the number of the wit- 

 nesses, would not add to the weight of testimony. 



Mr. Scarlett said, he would show, by a series of experiments 

 made by men of the first eminence, that his clients had a good 

 defence. 



Mr. J. Deville and Mr. Biamer were then called : they both 

 agreed in the superiority of the new over the old plan, and de- 

 posed to the difficulty with which gas can be produced from oil, 

 and the comparative ease with which it can be formed from 

 sugar. 



Henry May was again examined by Mr. Scarlett. — When he 

 called to Mulier, he did not know whether the gas-lamps were 

 lighted or not. He heard Muiler speaK, but he did not see him. 

 He had worked 24 years with his master. Mulier had been there 

 about a year and a half. He did not know whether there was 

 any other man in the fill-room with Mulier. 



This closed the case for the plaintiffs. 



Mr. Scarlett proceeded to address the jury for the defendants. 

 It was with unfeigned reluctance that he was obliged to occupy 

 a considerable portion of their time, after the great attention 

 which they had yesterday paid to this cause. He should not, 

 however, trespass longer on their time than was absolutely neces- 

 sary; for, independently of his desire to consult the convenience 

 of his lordship and the jury, he was under the necessity of being 

 as brief as possible, in consecjuence of his own indisposition, oc- 

 casioned
