3o6 THE POPULAR SCIENCE MONTHLY. 



strated l>y Marcellus Malpighius, who was born the very year that 

 Harvey's work was published, 1628. 



I will conclude my long story by merely mentioning the discov- 

 eries of the lacteals, the receptacle of the chyle, and the lymphatics. 



Harvey discovered the circulation in 1619, and published it in 1628. 

 Aselli discovered the lacteals in 1622 ; Pecquet the receptacle of the 

 chyle in 1648; Rudbeck and Thomas Bartholin the lymphatics be- 

 tween 1650 and 1652. This was a glorious period indeed ! 



Thus it came to pass that the united labors of all these worthy 

 men and labors they were, and worthy men were they resulted in 

 giving the world a simple, clear, and satisfactory solution of the 

 manner of the circulation of the nutrient fluids of the body. 



Next all-fools-day will be the tercentenary of Harvey, when all 

 Christendom ought to be interested in the justice of bis claims to the 

 glory of consummating a discovery of so much consequence to man- 

 kind. No mere national pride should bias the minds of men whereby 

 memorials may be placed at Rome, Pisa, and Bologna, in rivalry with 

 that which is to be erected at Folkestone, in England, to commem- 

 orate the time and place of Harvey's birth.

WHY does the prevailing business depression continue ? Why 

 are the times so " hard ? " Why is the long-hoped-for revival 

 of trade so backward ? What is it that has put the times so disas- 

 trously out of joint ? 



Every one is asking these questions, and nearly every one is ready 

 with an answer. Some will declare that the trouble is all of the green- 

 backs ; others will go so far as to affirm that the lack of greenbacks is 

 the cause. Almost every one will assert that over-speculation has 

 something to do with it : some will attribute the whole mischief to 

 the intense railway "craze" of a few years ago, and the consequent 

 losses. Not a few are confident that extravagance and over-trading 

 are the explanation. There seems to be no general agreement of 

 opinion ; even men of equal business knowledge and experience dif- 

 fer essentially in their views as to the genesis and remedy of the 

 evil, and the professors of political science are scarcely nearer of 

 accord. 



There has recently come from an eminent English authority in 

 political economy an authoritative declaration in the matter. No one 

 will deny that Prof. Bonamy Price's essay denominated " One per
