THE HISTORY OF THIS WORK. Vll 



plates would be required, two-thirds of which would 

 have to be coloured either wholly or in part, and that 

 the letterpress would not exceed one hundred pages 

 quarto. 



1865, Sept, 1. Read a letter from Mr. Alder stating that 

 Mr. Hancock expected to complete his investigations of 

 the Anatomy of the Tunicata at the end of this year, 

 and that they hoped that they should have the Mono- 

 graph ready for the press by the end of the year 1866. 



1866, June 1. Read a letter from Mr. Joshua Alder stating

 memory of his late friend to do his best to prevent the 

 labours of his latter years from being lost to science.

 death called away Hancock's colleague, Joshua Alder, 

 on the 21st of January, 1807, in his seventy-fifth year. 

 Hancock was now more than ever anxious that the 

 monograph should be completed in the contemplated 

 manner, and he laboured at his investigations as 

 steadily as enfeebled health would permit. In the 

 following year lie published, as a first result of his 

 studies, a paper in the ' Journal of the Linnean 

 Society,' vol. ix, "On t/tr Anatomy and Physiology of
