subjects ; his diagrams and botanical models designed 

 at this period have been used for some years at one 

 of the Metropolitan Hospitals in the class lectures. 



He threw himself, with great energy, into the work 

 of the London Glay Gluh and investigated the fossil 

 fruits and seeds from the Isle of Sheppey. In 1840 

 he began their history, but this publication was not 

 continued; one hundred and eighty thousand fossil 

 fruits and seeds are now in the British Museum as a 

 result of his industry in collecting. Through the 

 efforts of the earnest workers of the London Glay Gluh 

 arose, in 1847, the PalceontograpMcal Society, which 

 has done so much to make known the richness of the 

 fossils of our own country, and which has produced 

 up to June, 1882, thirty-six quarto volumes. At the 

 first establishment of the PalceontograpMcal Society 

 Dr. Bowerbank was its Honorary Secretary. He held 

 that ofl&ce a considerable time, and for the last ten 

 years of his life was its President. 



Entomology was another of his favourite studies in 

 early days. He wrote a valuable paper in the ' Entomo- 

 logical Magazine,' vol. i, p. 239, 1833, on the " Circula- 

 tion of the Blood in Insects ;" a second, ' Ent. Mag.,' vol. 

 iv, p. 179, 1837, on the " Distribution of the Tracheae 

 in the Wing of Ghrysopa Perla ;" and a third, ' Ent. 

 Mag.,' vol. V, p. 300, 1838, on the " Structure of the 

 Scales on the Wings of Lepidopterous Insects." 



Dr. Bowerbank was one of the originators of the Boy al 

 Microscopical Society, and filled the office of President. 

 He also frequently contributed to its Transactions. 



In the ' Monthly Microscopical Journal,' vol. iii, p. 

 281, 1870, will be found his account of the early im- 

 provements made in the microscope in 1828 by TuUy,
