Obituary — Rev. J. B. Reade, F.R.S., etc. 47 



edition of his greatest work, tlie " Lelirbuch. der Claemischen und 

 Physicalischen G-eologie," (2 vols., Bonn, 1847-1854), wliich was 

 finished in 1854, in which year an English translation (so much 

 augmented as in reality to be a second edition) was published by 

 the Cavendish- Society, under the personal superintendence of the 

 author, which work, for the first time, supplied a notable deficiency 

 in our scientific literature. In 1866 an entirely re-written new 

 German edition of this work, in three volumes, was completed ; and 

 up to the last days of the worthy Professor's life, he was occupied 

 in completing a supplement to this edition, which will bring it up to 

 date, and is expected to appear immediately. 



Space does not admit of our even giving the titles of the numerous 

 scientific papers and minor communications, or alluding to the 

 popular lectures and letters on scientific subjects, which appeared in 

 print between the years 1842 and 1849. The posthumous fame of 

 Professor Bischof will rest, however, mainly upon his most impor- 

 tant work on Chemical and Physical Geology, which embodies a 

 vast amount of data for future generalization. Even those men of 

 science who may not be inclined to adopt the late Professor's views 

 in their entirety, cannot but admire the wonderful perseverance and 

 sagacity which he brought to bear upon his chosen field of investiga- 

 tion, and admit that he must be regarded as the founder of the study 

 of chemical geology, a branch of science which every day is asserting 

 its claims to more distinct recognition. 



Professor Bischof had, what is rarely accorded to scientific men, 

 the happiness of seeing his labours universally appreciated during 

 his lifetime. Prussia gave him the decoration of the Eed Eagle, 

 whilst from Eussia he received the Order of St. Ann ; in England 

 he was awarded the gold Wollaston medal by the Geological 

 Society, and in 1861 was elected a honorary member of that 

 body, whilst most of the principal scientific institutions of Europe 

 enrolled him amongst their members. Up to the very last Professor 

 Bischof preserved his mental faculties quite unimpaired by either 

 age or infirmity; and whilst, in his public capacity, he was esteemed 

 by all, it must also be added, that in private life he was one of the 

 most amiable of men, as all who knew him can testify. D. F. 



Death of the Peesident of the Eoyal Microscopical Society. — 

 With deep regret we announce the death of the Eev. Joseph Ban- 

 croft Eeade, F.E.S., E.E.A.S., President of the Eoyal Microscopical 

 Society. He was a Scholar of Caius College, Cambridge ; and 

 obtained his B.A. degree in 1825, when he took high honours in the 

 Mathematical Tripos. He was curate of Eigworth, Leicestershire, 

 till 1829, and was successively curate and afternoon lecturer at the 

 parish church, Halifax, till 1832, and incumbent of Harrow Weald 

 till 1834. In 1839 he was presented by the Eoyal Astronomical 

 Society to the vicarage of Stone, near Aylesbury, and in 1859 to the
