Many Americans who would like to learn Karate, Judo, and Jujitsu have neither the time nor the money to devote to studying them. Thus those who teach these techniques throughout the United States are continually being asked to compile a single course of instruction in attack and defense. One such teacher, Karl Freudenberg-a prominent exponent of all three techniques-has here prepared a manual of essentials to help the man who wants to increase his fighting potential, a manual that, if studied diligently, will provide the reader with the means to make the best of his "natural weapons." Mr. Freudenberg's book offers chapters on using the hands as weapons, effective karate punching, the "Kung-fu chop," throwing preparation and techniques, and restraining methods. It should serve as an excellent introduction to the art and science of Karate, Judo, and Jujitsu.

Among terrestrial plants the vascular plants are the largest and the most con spicuous. Thus lignin is found in vascular plants such as lycopods, ferns, gymnosperms and angiosperms, whereas it is absent from simple plants such as fungi, and from all other organisms.
