Joseph Sidebotham was born in 1822, and died at Erlesdene, 

 Bowdon, on Saturday, May 30, 1884. 



He was brought up to the business of calico printing, and 

 for a long period was the head of a firm carrying on a very 

 successful trade in that department of industry, at Strines, in 

 Derbyshire. In early life he became interested in the study of 

 botli entomology and botany ; also in astronomical research, and 

 in counection with his intimate friend, Mr. James Nasmyth, C.E., 

 then of Patricroft, constructed some large and effective reflecting 

 telescopes. Amongst his other numerous pursuits, Mr. Side- 

 botham did not neglect photography, and on the publication of the 

 collodion process in 1851, he sought and obtained an interview 

 with the late Frederick Scott Archer, and was probably the first 

 to introduce the working details of that beautiful process to 

 lovers of photography in the north of England. 



He was one of the chief founders^of the Manchester Photo- 

 graphic Society, and became its first secretary, being a member 

 at the period of his death. The waxed-paper process in his hands, 

 as well as the collodio-albumen, were worked to great perfection, 

 and for several years he was a recognized leader in dry-plate 

 work. Of late years his health caused alarm to his family and 

 friends ; he spent two winters at Mentone, where he took a large 

 number of excellent negatives ou collodio-albumen plates. His 

 residence at that delightful watering-place seemed for a time to 

 recruit his strength considerably. 



He left three sons and three daughters. The burial took 

 place at the parish-church of Bowdon on Wednesday, June 2ud. 



Mr. Sidebotham published 25 papers, of which he is credited in 

 the Catalogue of Scientitic Papers of the Eoyal Society. His 

 first paj)er was " Plants collected in Westmoreland ;" and the 

 others are also of botanical and zoological character, entomology 

 being a favourite subject. 



Gael Theodoe Eenst von Siebold was born at Wlirzburg 

 on February 16, 1801, and was brother of the Japanese traveller 

 and botanist. He was bred to the medical profession, and prac- 

 tised for some time at Ktinigsberg until 1835, when he was 

 appointed Master of the Lying-in Hospital at Dantzic. In 1840 

 he moved to Erlangen, there teaching comparative anatomy and 

 zoology. Five years later he was made Professor of Zoology at 

 Freiburg, and there began his ' Lehrbuch der vergleicheuden 

 Anatomie der wirbellosen Thiere,' in conjunction with others. 

 In 1849 he started, in conjunction with Kolliker, the ' Zeitschrift 

 fiir wissenschaftliche Zoologie,' which still is the most prominent 

 zoological periodical in Germany. The next year he became 

 Professor at Breslau; and in 1853 he was appointed to the Uni- 

 versity of Munich to fill the chair of Comparative Anatomy, and 

 Director of the Zoological Cabinet ; these positions he retained 

 to the last. He was elected a Foreign Member of our Society
