...canal leading up the spinal column to the brain. He has hair and warm blood like other animals. He produces young in the same way. He suffers from the same poisons as do the great apes, and from diseases similar to theirs. He is even preyed upon by similar lice and fleas. He differs in degree, to be sure, from other animals, but not in kind. And those animals set down as his nearest relatives are more and more nearly like him in these respects. Indeed, there is less anatomical difference between man and the higher apes than between...
...honored when a Wellesley newspaper places it in that category of places to which journalism so rarely applies biblical verses. But we regret that Wellesley has already imbibed the spirit of Dr. Moffatt's new version of the Bible. Dr. Moffatt felt justified in changing 'ark' to 'barge' and 'lice' to 'mosquitoes' so that the Bible again might become a living document.

Artificial Fertilization. Biologists had long known that certain low invertebrates, such as rotifers or plant lice, normally reproduce themselves without fertilization by the male, by a process called parthenogenesis (virgin birth). Loeb proved that in many other species parthenogenesis can be induced artificially by treating the egg in various ways, i.e., keeping it in sea water, in salt or sugar concentrations at a certain temperature, in certain acid solutions, pricking it with a needle. In 1899 he caused the unfertilized eggs of sea-urchins to 'develop into swimming larvae and remain alive. Similar results were obtained with starfish, worms...
...insect-borne diseases and soon afterwards Ross discovered that human malaria is transmitted by the mosquito, and Reed, Carrol, and the Army Medical Commission demonstrated that yellow fever is transmitted also by a mosquito. Since then it has been shown that plaque is transmitted by fleas, typhus fever by lice, and relapsing fever by bedbugs, and the bites of many other insects have been shown to be dangerous. Dr. Smith has also conducted exhaustive researches on tuberculosis, was the first to recognize that there were distinct differences between the bovine and human tubercle bacilli, and contributed to our knowledge...
