– Devil take it, ice thawed under legs! – Kazn shouted. – I failed and now I cannot get out. When I grab the edge of ice, ice thaws and turns into water…

I made out a vague spot of the Kaziny head and grabbed at random a hand. Yes, it was the hand if only I did not grab for burning головню: heat of this hand was felt even through my fur mitten. «However what temperature of his body has to be?» – with surprise I thought.

We pulled out our friend on the coast. From an ice bathtub on a forty-degree frost! But unfortunate Kazya delirious and fire of fever did not feel cold and danger. It was stirred up as the bear who got out of water and ran from us along the lake. It was easy for it to run. He ran on the trampled-down road with a speed of a dog, we in our fur suits could not catch up with him. The shining sphere of our «steam» friend sparkled on a hillock soon and disappeared.

What to do? To run after Dashkevich? But we could not leave radio station for a long time. In our work and so there was a break. We decided that one of us has to go to work, and another will be engaged in searches of the run-away patient. But as Dashkevich was stronger than each of us separately, we decided to invite to the help of professor Wagner. Pronin hurried on radio station, and I rushed off to Wagner.

– What did you make with our friend? – I asked Wagner.

Professor looked at me with one eye and answered, without coming off the lamp transmitter:

– I nothing to it made bad. And what our patient? How he feels?

– Ran away! – hasty I answered. – Ran away when it has probably not less than forty degrees temperature. Naked ran away!

Professor Wagner smiled.

– Good feature? – he asked, pointing to the device. – You did not meet such design yet.

The device was really entertaining, but to me had no time for it.

– Korotkovolnovik? – carelessly I asked and, without waiting for the answer, continued: – Listen, professor, leave your experiences and help me to catch and return our escaped friend until he died finally.

– At a usual order of things – Wagner answered, without moving a little – companion Dashkevich had to die long ago. And we would need to search for his dead icy body only. But as companion Dashkevich feels excellently…

– From where you know it?

– From your own words. Dashkevich did not die, even покупавшись in the lake. He breathes in couples as the engine, and walks in shorts behind the Polar circle as though it on the beach in the Crimea. Do not worry about your Kaz, you sit down here here and listen. You asked what I made with Dashkevich.

– But, professor, now not time…

– It is a high time! You sit down. I assure you that with Kazy nothing bad happens. Experience was successful.

– Again experience? – with astonishment I asked.

– Well, certainly.

Wagner unexpectedly squeezed my hand at an elbow. I screamed.

– Painfully? I and thought. You are hurt by joints when you work with the regenerative receiver. You feel temperature increase. Well, opened radio, but still did not study character of this animal at all. The fact that we know about radio, is just baby talk. Our knowledge and scope of radio extend every day. You know that doctors for treatment of some diseases began to use short waves now, artificially lifting radio waves the body temperature of patients. And here the thought came to my mind: and why not to heat artificially human body by means of short radio waves?

– But the human body is naturally heated – I told.

– Yes, but it is not enough. The healthy person possesses automatic change of temperature in only five-seven tenth degrees throughout days. On a disease the human body reacts increase or fall of temperature to two-three degrees against norm. Extreme limits of fluctuations make only six-seven degrees.
