CHAPTER XI 

 PRESERVATION OF MARINE ORGANISMS 



BY E. J. ALLEN AND EDWARD T. BROWNE 



Introduction. 



It is impossible within the space allotted to this 

 section to describe in any detail all the numerous 

 methods for the preservation of marine organisms. 

 We have selected the simplest methods, which, if care- 

 fully carried out, should yield good results. Those 

 who require their specimens preserved by refined 

 methods for minute microscopical investigations are 

 strongly advised to consult that indispensable book, 

 " The Microtomist's Vade-Mecum," by Dr. A. Bolles 

 Lee. This book should be in the hands of every marine 

 naturalist, and we have frequently consulted its pages 

 for this chapter. We are also indebted for methods 

 to Dr. S. F. Harmer and Mr. R. L. Leiper, and 

 especially to Mr. A. J. Smith, who has charge of the 

 Preservation Department in the Marine Laboratory at 

 Plymouth. 



The subject matter of this chapter is really in two 

 parts. General information and simple methods such 

 as are within every traveller's power are printed in 

 large type ; but the more technical and delicate methods 

 of preservation, for detailed microscopic study rather 

 than faunistic collection, are printed in a smaller type ;
