Otto Butschli was born in Frankfurt, the son of a Swiss who 

 had settk-d in that town, and niarried a lady who had lived all her 

 life there, Emilie Kulimann. Our late Foreign Member was born 

 on the 3rd May, 1848. After early school-days he turned his 

 attention to mineralogic chemistry and palaeontology, and at 

 17 years of age became assistant to Zittel ; then spent twelve 

 months at Heidelberg and graduated with mineralogj^ as his 

 principal subject. It was now that interest for living nature 

 awoke in him, and then it took possession of him. Except during 

 one semester under Leuckart in Leipzig, he was self-taught. In 

 1869 to 1876 he lived with slight breaks in Frankfurt, served in

 became for two year's assistant to Mcibius in Kiel. By this time 

 lie had published many papers on Protozoa, the development 

 and morphology of invertebrates. In 1878, whilst still under 

 30 years of age, he became Professor of Zoology and Palaeont- 

 ology in Heidelberg, where he remained to the end, in spite of 

 many flattering invitations elsewhere. Butschli had the teaching 

 talent, though towards the last he began to feel his duties some-

 and unable to withstand a severe illness which came on. 



Studies on the cell-division and conjugation of the Infusoria was 

 Biitschli's first important work, which appeared in 1876 in the 

 Senckenberg Abliandlnngen. This, together with Strasburger's 

 work on the doctrine of tlie cell, established these observations on
