 of the immune strain, he asserts, either fails to develop and is quick ly eliminated or, after growing to a tumor the size of walnut, IS overcome and gradually disappears. That he regards as tae most hope ful result of his work thus far. He 's convinced that the animals of ,be immune strain whe,. infected develop some unidentified, natural ahti-toxin which destroys the can cer cells without damaging the normal tissue.
 Agent May Re Isolated
 "The hypotheses on which l have been working contains two postu- lates,' he explains. First. that in order for an animal to develop cancer it must have special kind of tissue, and, second, that in order for this special kind of tissue to change into a cancer this tissue must have a prolonged contact with some external and internal chemi- cal agent or agents.
 These substances are probably derived from the decomposition products of vegetables and animal tissue Such agents are found in coal tar. in shale oil and in the products of certain worms. It is quite reasonable to suppose that they may be isolated so that we will know just what the chemical agent or agents are. If this could be done great light would be thrown on the whole subject and definite preventive measures could be taken"
 Investigating the cffeHt : heat on ca..ccr cells. Dr. ".!#'a' hi45 fouEd ilt:ther .ur re ot r''n'::=:t uccess in the wsr on the disease. ha,i1g dete,m!neG that, although immortal at normal temperatures, they die after being subjected to II ? degrees iAl ehici'' io- o' minutes. Cells thus heated in test tube and then ingrafted in q susceptible rat, he says, have nev- CT developed.
 Carrying this experiment fur , ther, he has brought the tempera- ture of cancerous rats under eth CT to 111h degrees and held them in that condition for an hour. On- , few survived the experiment long enough to permit removal of their cancer tissue while they were | till alive to other susceptible rats. In every case. he asserts. the can cer cells were dead and caused no growth.
 Seeks Revival Method
 The problem raised by these ex- periments is to find a way to re- store the rats to health after put ting them through the 30-minute temperature test Dr. Walker learn
 
 30 minutes at 10Sla degrees, but none lived longer than six hours after being subjected to the. can cer destroying temperature. If a method can be worked out to keep the rats alive after subjecting them to the higher temperature and the biological law thus established can be shown to apply to the human race, he feels that realization of the dream of a cure. for this non conta gious but widely prevalent disease will be only a matter of detail.
 That the disease is non-cantag- fous has been accepted more or less generally by physicians for some time, hut Dr. Walker. with rats at his disposal which clearly | inherit a distinct susceptible to cancer, has been at pains to test the truth of this conclusion for his own satisfaction and for the 2 reinsurance Of those who come in contact with affected patients. Many persons who are in daily contact with cancer patients are very much frightened for fear that they themselves might take the disease" he observes. "In order to throw some light on his sub- ject I have taken rats of my very snscemible strain and mt them in
