22 Obituary Notices of Fellows deceased. 



Apart from all his other activities and constant hearty encourage- 

 ment of his pupils and assistants, Leuckart for a long series of years 

 rendered a great service to the zoological world by his admirable 

 annual ' Bericht ' or critical report on the progress of knowledge with 

 regard to the anatomy and life-history of Invertebrata. Though the 

 reports were often a couple of years later than the date of the memoirs 

 recorded and epitomised, yet they were always looked for and read 

 with great interest, on account both of the faculty which Leuckart had 

 of bringing to light little-known and out-of-the-way publications of real 

 value, and for the critical judgment and knowledge which he possessed 

 and made use of so as to give significance to the observations of other 

 workers which might otherwise have passed into oblivion. Rudolf 

 Leuckart was a sturdy honest worker of first-rate ability and of wide 

 sympathy and grasp of his subject. He rendered services of the 

 highest value to the science to which he devoted his life, and his name 

 will ever be held in veneration by zoologists and comparative anato- 

 mists. 



It is worth while, perhaps, to draw attention as a last word to the 

 fact that, more than is the case with other zoologists of distinction, 

 Leuckart directed his work very frequently towards results of practical 

 or economic utility as, for instance, in the. case of so many of his 

 researches on parasitic worms and of his treatise on the honey-bee.
