"If you are satisfied that there was a design to effect death, but without deliberation and premeditation, you may find murder in the second degree. The defendant may be convicted under this indictment of murder in the first or second degree or manslaughter in the first degree.
"When it appears that the defendant committed a crime and there is reasonable doubt of which degree he is guilty, he can be convicted of the lowest only.

"The law presumes that sanity is the normal condition
