1878 WORK OF THE YEAR 243 



The Liberals are making fools of themselves, and " the 

 family " declare I am becoming a Jingo ! Another speech 

 from Gladstone is expected to complete my conversion. 



Among other occupations he still had to attend 

 the Scottish Universities Commission, for which he 

 wrote the paragraph on examinations in its report; 

 he lectured on the Hand at the Working Men's 

 College ; prepared new editions of the Physiography, 

 Elementary Physiology, and Vertebrate Anatomy, and at

 June 3 he lectured to working men at Jermyn Street

 and Distribution of Crayfishes at the Zoological 

 Society on June 4, and lectured at the Zoological 

 Gardens weekly from May 17 to June 21 on Crus- 

 taceous Animals. In all this work lay the foundations 

 of his subsequent book on the Crayfish, which I find 

 jotted down in the notes of this year to be written 

 as an introduction to Zoology, together with the 

 " Dog " as an introduction to the Mammalia, and 

 Man already dealt with in Man's Place in Nature 

 as an introduction to Anthropology. This projected 

 series is completed with a half -erased note of an

 year. 



He notes down also, work on the Ascidians, and
