This article contains a general account of the writer^s expe- 
riences in the Cape de Verde Islands during the first month of 
his residence there, from Christmas 1864 to 22nd January 1865. 
It consists chiefly of a description of the author^s travels in the 
t^yo islands, S. Vicente and S. Antao, visited by him, but includes 
no special entomological information.

628 : January 25, 1865. 
In this presidential address, the last work of its veteran author, 
we have a somewhat rapid sketch of the present state of our 
knowledge of many interesting departments of entomological 
study, accompanied by indications of existing deficiencies and 
of the course in which investigations should be directed in order 
to fill up these gaps. 
ScHAUM, H. Zur Beseitigung von Missverstandnissen. Wiener 
entom. Monatsschrift. viii. pp. 55-58 : February 1864. 
This paper, whicli is in reply to an article by Schiner (Wien, 
ent. Mon. Bd. vii.), is in support of the view entertained by 
several continental entomologists that the works of certain 
authors who are notorious for the production of imperfect 
descriptions, and for a careless and uncritical arrangement of 
their materials, should be entirely ignored by their successors. 
It may be granted that the writings specially referred to by Dr. 
Schaum are really worse than useless, but unless their rejection 
by entomologists of future generations can be assured, those of 
the present day must be content to accept the burden thus laid 
upon them and make the best they can of it.

Diseases as affecting domesticated animals. Journ. Boy. 
Agricult, Soc. 2nd series, vol. i. pp. 33-72 1865. 
This paper contains a series of observations on the occurrence 
of parasitic insects and Acarina on domesticated animals, their 
eflects, and the treatment necessary when these become trouble- 
some or injurious. There is nothing new in a natural-history 
point of view in this paper.
