Clarke noted that at the time of death there is a sudden rise in body temperature as the lungs are no longer cooling blood, causing a subsequent rise in sweating which could easily account for MacDougall’s missing 21 grams. Clarke also pointed out that, as dogs do not have sweat glands, they would not lose weight in this manner after death.[2][2] Clarke's criticism was published in the May issue of American Medicine. Arguments between MacDougall and Clarke debating the validity of the experiment continued to be published in the journal until at least December that year.[3]
