i was kept from leaving my studies by one person, herman fund gel-goltz, who did not praise my theoryt suggested classes in his physics laboratory. said he saw a scientific streak in me. now your brother is back winged is keen on experiments. dear sigismult, i think that work in the direction of gases is both very promising and very risky. remember the experiments of the young hemfriday to the teacher faraday, how many explosions accompanied the discovery of the laughing gas nitrous oxide. and how many we do not know gases when heated distillation under pressure can behave unpredictably. you're taking a big risk, plus your eyesight and sorry absent-mindedness, multiplied by your perseverance. i beg you, please, be careful, your loving brother edward never heard of a practice session. and we don’t have such people, only if the students are already engaged in the experiments of experimenters , in addition to discovering the phenomenon of electromagnetic induction, he managed to convert some types of gases into a liquid state, at the beginning he received liquid chlorine, then all the re
