which were translated from foreign languages, and 

 man}' by his own pen. With the assistance of Mr. 

 George Busk he made a translation of Kolliker's His- 

 tology, a great treatise on microscopic anatomy which 

 played a large part in the development of the modern 

 English schools of anatomy and physiology. He made 

 some valuable contributions to Todd and Bowman's 

 Cyclopaedia of Anatofuy, an elaborate publication now 

 nearl}' forgotten and practically superseded, but which 

 was the standard anatomical work of the middle of this 

 century. He was unable to progress rapidly with his 

 work upon oceanic Medusas, as he was uncertain how 

 to have it published ; the Admiralty refused to assist, 

 and it was too lengthy for publication in the volumes 

 of the learned Societies. As a matter of fact, he did not 

 publish it until 1858, when it appeared as a separate 

 memoir. To the Quarterly Journal of Microscopical 

 Science and to the Transactions of the Royal and Liiince an 

 Societies he contributed a large number of memoirs 

 dealing with the microscopic anatomy and relation- 

 ships of invertebrates, and, lastl}', he gave a series of 

 addresses at the Royal Institution, which had been 

 founded as a means by which leading men of science 

 might give accounts of their work to London society. 

 Abstracts of these lectures are published in the early 

 volumes of the Proceedings of the Royal Instifnfion and 

 are interesting as shewing the kinds of zoological sub- 

 jects which were attracting the attention of Huxley 

 and which he considered of sufficient interest and im- 

 portance to bring to the notice of the general public. 

 The first of these lectures, and probably the first given 

 in public by Huxley, occurred on April 30, 1852, and 

 was entitled " Animal Individuality." The problem as 



to what is meant by an individual had been raised in
