PREFACE TO ENGLISH EDITION. 



Mr. E. E. Austen, of the British Museum, has been 

 good enough to undertake the translation of my book on 

 "Venoms." For the presentation of my work to the 

 scientific pubhc in an English dress I could not have hoped 

 to find a more faithful interpreter. To him I express my 

 liveliest gratitude for the trouble that he has so kindly 

 taken, and I thank Messrs. John Bale, Sons and Danielsson 

 for the care they have bestowed upon the preparation of 

 this edition.
