THE LARGEST PYRAMID. 379 



less than one fifteen-thousandth part of a grain, a quantity barely visible to the 

 naked eye. 



Third — Hence, when an ignorant criminal attempts to explain suspicious 

 blood-spots upon his clothing, weapons, etc., by attributing them to the ox, pig, 

 sheep or goat, or to any of the birds used for food, we can, under favorable cir- 

 cumstances absolutely disprove his false statement, and materially aid the cause of 

 justice by breaking down his lying defense, even if twenty years have elapsed. 



Fourth — But, if the accused person ascribes the tell-tale blood to a dog, 

 an elephant, a capybara, or any other animal in Dr. Woodward's list, it is useless 

 to attempt to dispute his story on microscopical evidence as to the size of the 

 blood corpuscles. 



Fifth — In cases of innocent persons wrongfully accused of murder, and 

 really stained with the blood of an ox, pig, or sheep, testimony of experts, found- 

 ed upon measurement of the corpuscles, would be valuable, but less conclusive, 

 because, under certain circumstances, human blood-corpuscles may shrink to the 

 size of those of the ox, whilst under no known condition do ox or pig corpuscles 

 expand to the magnitude of those in human blood. 



Sixth — In order to do away with ingenious objections of lawyers that the 

 murdered person may have been affected with some disease which altered the 

 size of his blood disks, or that the articles of clothing, etc., upon which the stains 

 were deposited had produced, chemically or otherwise, some similar change in 

 their magnitudes, it is very important to obtain, promptly, stains from the fresh 

 blood of the victim, made in the presence of witnesses, upon portions of the pris- 

 oner's clothing, or weapons analogous to those upon which suspicious red spots 

 are found when he is arrested. When this cannot be done, spots of the murdered 

 person's blood, sprinkled on white paper, and fragments of his lungs and kidneys, 

 should be carefully preserved, the former by rapid drying and the latter by pre- 

 servation in diluted alcohol. These little precautions, which may in any instance, 

 prove to be of infinite importance, should be earnestly impressed upon coroners, 

 district attorneys and policemen, throughout the civilized world. — American

THE LARGEST PYRAMID. 



We believe it is not generally known that the largest existing pyramid rests 

 on American soil. The Pyramid of Pueblo, in Mexico, is larger than the great 

 Pyramid of Cheops, in Egypt. The latter covers only fourteen acres, while the 

 Mexican one covers forty-four acres of ground and was originally 600 feet high. 

 It is made "of sun-dried brick, and is supposed to have been built 7,000 years ago.
