 T. H. HuxLET. 12ino. Cloth, $1.50. 



" Of the essays that have been collected by Professor Huxley in this volume, 

 the first four deal with some aspect of education. Most of the remainder are 

 expositions of the results of hioloi^ical research, and, at the same time, illustra- 

 tions i»r the history of scientific ideas. Some of these are among the most inter- 

 estintj of Professor Huxley's contributions to the literature of science.'' — London 

 Academy. 



" When weary of the iteration of old thoughts dressed up in new phrases, it 

 is refreshing to be brought into converse with one of the most vigorous and acute 

 thinkers of our time, who has the power of putting his thoughts into language so 

 clear and forcible."— Zowrfow Spectator. 



CAPITAIi AND POPUIiATION: A Stndy of the Economic Effects 



of their Relations to Each Other. By Frederick B. Hawlet. 



12mo, cloth. Price, $1.50. 



" It would be false modesty in me to seem unaware that the economic law I 



have attempted to establit^h equals in its influence upon economic conclusions 



anyhitlierto ascertained. Granted its trutli, it throws new and decisive light 



on nearly all the unsolved problems of the science." — Extract from Preface.

Felix L. Oswald, M. D. 12mo. Cloth, $1.00. 



Contents : Diet, In-door Life, Outdoor Life, Gymnastics. Clothing, Sleep, 

 Recreation, Remedial Education, Hygienic Precautions, Popular Fallacies. 



"The author strikes right and left at the lingering traces of the traditional 

 asceticism which has had so much influence in warpini: our systems of education 

 and life. He insists, at the outset, that the monkish identification of the human 

 body with Satan and sin shall be discarded utterly, and that we shall regard this 

 tabernacle of clay as the most perfect structure of the divine architect, and as the 

 sole meaiis by which we can work out our salvation. Nature is the author's 

 supreme law, and his cure for all maladies of the iadividual and the community 

 is right living." — Home Journal. 



" Dr. Oswald is as epigrammatic as Emerson, as spicy as Montaigne, and as 

 caustic as Heine."— PAitade/p/tJa Press. 



THE PRINCIPLES OF THE L,AW : An Examination of the Law 

 of Personal Rights, to «liscover the Principles of the La'w, as 

 ascertained from the Practical Rules of the La^v, and har- 

 monized with the Nature of Social Relations. By A. J. Will;ird. 

 8vo, cloth. Price, $2.50. 

 " A calm, dignified, able, and exhaustive treatise of a subject which is of erreat 

 importance to every one. Mr. Willard first discusses the nature and origin of 

 rights, obligations, and powers of fundamental social law and institutional law. 

 He then expounds the science of law and defines the nature of all species of obli- 

 gations and contracts. A general view of rights and powers is then brought 

 forward, and a consideration of their special functions, as, for instance, the use 

 of air and wa'er and the principles of Individual sustenance. The doctrine of 

 individual redress and protection is thoroughly examined, and a long and inter- 

 esting discussion follows of nuisance*, wroiigs, and injuries. The characteriza- 

 tion of dueling and the pithy and convincing way in which its absurdity is shown 

 rt re admirable. The treatment of the subject is so clear and logical, so simple 

 and scholarly, that it deserves the hiirhest praise. It is a work such as Aristotle 

 might have written, had he lived in this latter day." — Philadelphia Press.
