partment of zoology to purchase a part of the ‘ Record ’ 
containing that which relates to their subject, without 
having to pay for the whole. The vertebrates form one 
part ; the insects, spiders, and myriopods another ; and the 
rest of the invertebrates, a third. It is this last volume 
which will be of most interest to our readers, containing as 
it does the literature relating to the minuter forms of animal 
life. Dr. Edouard von Martens has given account of the 
papers and separate works relating to the class Mollusca, 
and to the great group of Crustacea, which appeared during 
the year 1867 ; whilst Professor Perceval Wright, of Trinity 
College, Dublin, has done the same for the Molluscoida, 
Rotifera, Annelida, Scolecida, Echinodermata, Caelenterata 
and Protozoa. The study of all these groups is intimately 
associated with the microscope ; and it is pleasant to see the 
pages of this Journal not unfrequentlv referred to in the 
‘Record.’ No fitter recorder than Dr. Wright could have 
been found for the work, which he has done with the same 
ability as in former years. We could, however, wish one 
thing ; and that is, that space would permit the recorders to 
give a short account of many of the papers which now are 
merely entered by their titles. Though, in our own chro- 
nicle, we attempt to keep a record of the current literature 
relating to microscopic organisms, it is yet not possible for 
us to obtain the same survey as the yearly recorder ; and in 
his pages will be found references to some works and papers 
on microzoological subjects which have not come under our 
notice : besides this, many of those who work with the 
microscope are doubtless interested in special branches of 
zoology ; and to those the Zoological Record will be invalu- 
able. As a matter of duty, those who wish for the progress 
of zoological science in this country, and who can afford it, 
as we trust many can, should prove their regard for science 
by the purchase of the ‘ Zoological Record.’
