patches of ulceration on their skins resulting from poisoned 
wounds. 
Baron F. Von Mueller supplies a “ Census of the Plants of 
Tasmania,” up to 1879. 
Mr. Justice Dobson and A. Simson both contribute papers on 
the codlin moth ( Carpocapsa pomonella ), a depredator which is 
committing serious mischief in the apple and plum orchards of 
the colony. 
R. M. Johnston gives a memoir on the “ Natural History of 
the Marine Tertiaries of Table Cape,” with a description of 
thirty new species of Mollusca ; and notes on the “ Distribution 
and Variability of Tasmanian Land Shells.” 
The Right Rev. Bishop Bromby, D.D., read a paper on the 
** Law of Storms,” with especial reference to the Southern He- 
misphere. He considers that in the Tasmanian waters a storm 
generally arises from a conflict between an easterly and a 
westerly wind, the easterly always flowing on the polar side of 
the westerly. 
We are happy to find that there are in Tasmania persevering 
and able observers who turn their attention to local phenomena, 
The Microscope and its Revelations. By W. B. Carpenter, 
C.B., M.D., LL.D., F.R.S., &c. Sixth Edition. Pp. 882, 
26 Plates, 500 Wood Engravings. London : J. and A. 
Churchill. 1881. 
It is pleasing to see another edition of this well-known hand- 
book. Our veteran microscopist has undertaken the work with 
his old vigour undiminished ; keen both in sight and intellect. 
No new discovery has escaped him, and the book faithfully re- 
presents the state of microscopical science up to the time of 
going to press. 
The title naturally suggests the plan of the work ; this, indeed, 
has been but little changed through the whole of the six editions, 
save in the alteration caused by scientific progress, and the 
extension of some important subjects. To the instrument itself 
four chapters are devoted, the first containing a plain account of 
the optical principles of the microscope, the remaining ones con- 
taining a description of the various kinds of microscopes made 
both in England and abroad, and the various accessory apparatus 
employed. The mode of using the microscope is described at 
great length. The notes on errors of interpretation are very im- 
portant, and include the new discoveries of Professor Abbe on 
diffraction spectra. The value of these cannot be overrated, and 
Dr. Carpenter has done well to give great prominence to the
