¶1In the Knox Circuit Court appellant by affidavit was charged with the crime of arson. Acts 1905 p. 584, §2260 Burns 1914. To this affidavit appellant entered a plea of not guilty, and also a special *534plea of insanity was filed. He was tried by a jury and convicted. Following the overruling of his motion for a new trial, he was sentenced to imprisonment in the state’s prison for a period of from two to twenty-one years and fined $500.

¶5Under this showing we hold that the court erred in refusing .to instruct the jury at the close of the opening argument for the state, as requested by counsel for defendant. §2136 Burns 1914, cl. 4, Acts 1909 p. 257.
¶6*535Judgment reversed, with, instructions to the trial court to sustain appellant’s motion for a new trial, and for further proceedings not inconsistent with this opinion.
