Show Can the Blood of Baboons Be Transfused Into the Veins of Meii?bs) CAN the blood of apes and anthropoid monkeys be injected into the veins of human beings without injury to the latter? Paul C. Van Natta, anthropologist in the Smithsonian Institution, Institu-tion, says that he knows of no satisfactory experimental ex-perimental results concerning this question, though it is generally considered, for obvious reasons, rea-sons, that the blood from one species cannot be transfused into the veins of an animal of another species or genus without serious consequence to the latter. Dr. David Starr Jordan, president emeritus of Leland Stanford University, in a statement made to the Pathfinder, calls attention to the following statement found in "Evolution and Animal Life," written by Dr. Jordan in collaboration with Dr. ' Kellogg: "Friedenthal finds that while the blood serum of man is poisonous to, and destroys the red blood corpuscles cf all other animals experi- mented on, these animals, including fishes, r.m- Vrf phibians, reptiles, birds and mammals, .imo-ig ! which latter were lemurs and New and Old World V !ai; monkeys, it docs not injure the corpuscles of the f. y man-apes (orang, gibbon, chimpanzee) . This im- vXj j m unity exists only among the closely related j animals, as the horse and donkey, dog and wolf, J i hare and rabbit; from which it is evident that ! man and the man-apes have nearly identical TAnl'ii i blood." VjPtv "Friedenthai's statement," says Dr. Jordan, f ' "which I never have verified, has been accepted JJ l without question by all the writers I have noticed. 5 The most recent investigator, is that of Dr. jx -NX George H. F. Nuttall, of Cambridge, referred to -'- by Dr. Kellogg in his volume, 'Evolution.' " J1!; Dr. Kellogg's statement reads as follows- "There should be added to this brief accoum ot ) ,"t the evidences of human evolution at least a ic:;- jy ' erence to the interesting blood tests devised bv Ci Dr. Gorge Nuttall, of Cambridge, England, anil Vra others, which indicate the chemical likeness of -2s the blood of the anthropoid apes and that of P C1 ' man. c "These facts, called precipitin tests, are based J!-' on the discovery that if the fresh b)oad serum T' ' of any animal is injected into the veins of a rab- (.N' bit, there vill be produced in the rabbit's blood !;' an antibody. This is analogous to the antitoxin i-J which is produced in the blood of a horse by in- l1 . jecting diphtheria virus. vVi "Now, if into blood, taken from an animal of the same species as that from which serum wa. r originally injected into the rabbit's body, thrr.
