viii PREFACE TO THE FIRST EDITION 



to illustrate the principles of the subject under consideration. In a work 

 of this size an exhaustive treatment of this number of drugs could not 

 be given, but by a brief mention of them material for study is indicated. 

 It may be mentioned in this connection that wherever metric measure- 

 ments are given, these are stated in millimeters; this has been deemed 

 advisable for the purpose of comparison. 



The illustrations included in Part I are taken mainly from Bentley's 

 "Manual of Botany," to the author of which our thanks are due. An 

 exception, however, is found in the drawings of the starches, which were 

 prepared from original specimens. The remaining illustrations, with the 

 exception of those in the Chapter on Animal Drugs, have been prepared 

 under the direction of C. E. McClung, Ph. G., a graduate of the Kansas 

 State University School of Pharmacy, class of '92. All the drawings of 

 the cross-sections are drawn directly from sections prepared by him, the 

 cell contents being first removed by the method described in Appendix 

 C. It has been our aim to present the elements of each drug in their 

 true proportions. As often as possible the cells in their exact shape and 

 relative size have been drawn, and in no case has meaningless shading 

 been employed. For some of the drawings of the medicinal plants credit 

 is given below in the Bibliography. The illustrator has kindly furnished 

 a Chapter on Pharmacal Microscopy, which will be found in Appendix C. 



The author is much indebted to Professor Vernon Kellogg for informa- 

 tion concerning animal drugs used in pharmacy; also for Appendix B, in 

 which he treats of insects attacking drugs. The drawings to illustrate the 

 material furnished by Professor Kellogg are hereby credited to Miss Mary 

 Wellman, artist. 



For aid in the preparation of the text in Part I our thanks are due to 

 Mr. A. O. Garrett, who, in his university course, has made botany a 

 special study. 



Appendix B, upon the synthetic remedies, is the work of Mr. F. B. 

 Dains, who has made a specialty of organic chemistry and was instructor 

 in this subject in the University of Kansas during the year 1894. In 

 this section the new spelling of chemicals has been adopted only in a few 

 cases. 



To Dr. S. W. Williston, Professor of Physiology and Anatomy, who 

 has aided in the condensed description of therapeutic action; to Mr. 

 0. H. Parker and Mr. William Clark, members of the Senior Class of '94, 

 who assisted in the study of characteristics from crude specimens of drugs 

 in the open market; to Mr. W. O. Strother, of the same class, who sup- 

 plied a few drawings of cross-sections; and to Mr. W. F. Newton, of 

 the Junior Class, who materially aided not only in the study of drug char- 

 acteristics, but also in arranging the material, our thanks are due.
