“We were not able to make these records as perfect as we would like,” said Estra, holding up four disks similar to the ones which still lay in the explorers’ translating machines.  He proceeded to open the little black cases and make the exchange.  “There will be words used which I did not see fit to incorporate in the original vocabulary, but which you will have to understand perfectly if this announcement is to mean anything to you.”

“Thank you,” said the doctor quietly.  “And now, don’t you think we had best know in advance, just what is to be the subject of—­”

“Hush!” whispered Estra; and next second they were listening to the telephone in amazement.

THE WAR OF THE SEXES

“In accordance with my promise,” stated a high-pitched effeminate voice, “I am going to demonstrate a juvenation method upon which I have worked for the past one hundred and twenty-two years.”

There was a brief pause, during which Estra hurriedly explained that the man who was making the speech was located far on the other side of the planet, in a hall like the one the four had first visited; and that he was making the demonstration before a great gathering of scientists.  “Too bad you cannot see as we do,” commented the Venusian.  “However, Savarona may go into the details of—­”

“If the committeemen are entirely finished with their measurements,” stated the unseen experimenter, “I would like to have the results compared with the recorded figures of Pario Camenol, who was born on the two hundred and fifteenth day of the year twenty-one thousand seven hundred and four.”

Another rest, and Estra said:  “They are examining a boy who appears to be about twelve years of age.”

Then came other voices:  “As we all know, the craniums of us all are absolutely distinct; as much so as our finger-prints.”  “The measurements correspond identically with those of Pario Camenol, beyond a doubt.”  “This boy can be none other than Pario.”

“Then,” the high-pitched voice went on, “then notice the formula I have written on this blackboard.  Using this solution, I have supplied nourishment to this lad from the hour of his birth.  Until a few days ago, I was not satisfied with the results; the patient showed a tiny variation from the allowable subconscious maximum, together with only nine-tenths the required motor reaction.

“But I have corrected this.  Briefly, I have incorporated in Pario Camenol’s standard diet certain elements which have hitherto been unsafe to combine.  These elements are derivatives of the potash group, for the most part, together with phosphates which need a new classification.  Their effect,” impressively, “has been to postpone age indefinitely!”

There must have been a tremendous sensation in that hall.  The speaker’s voice shook with excitement as he went on: 

“We have sought in vain, friends, for a way to cheat death of his due.  We have succeeded in postponing his advent until our average longevity is several times greater than on our neighboring planet.  But so far, it has been a mere reprieve.
