470 The Museum Gazette 



list is designed for use as labels, and we can supply it as 

 a slip, printed only on one side, for cutting up. The mosses 

 named are all common ones. 



In collecting mosses for purposes of identification only, it 

 is not necessary to wait for their " fruiting." For minute 

 distinctions and for systematic arrangement the " fruit" is 

 essential, but a great number may be known and admired for 

 their leafage only, and are recognisable at almost any season 

 of the year. For study of this kind a vivarium is infinitely 

 preferable to dried specimens. We shall probably add to 

 our list of labels in an early number. 



Apropos of what we have written on Museums at p. 421, it 

 may be urged that a most important addition to the useful- 

 ness of a museum of whatever scope, is a Catalogue. This 

 must, of course, be adapted to the scope of the museum. It is 

 impossible to praise too highly the catalogues issued by the 

 various special departments of the British Museum. The only 

 wish which they leave unfulfilled, is that there were more of 

 them. They are full of modern knowledge and are most 

 useful additions to all museums. They are not, however, 

 nor is it to be desired that they should be, what is wanted 

 for an Educational Museum. Some of our large provincial 

 museums have their own catalogues, but they are seldom 

 complete, and almost never kept up to date. For Educational 

 Museums it would be quite feasible to prepare a catalogue 

 which should be adapted for all, and thus save expense in 

 printing, and labour in preparation. It would also be of 

 great value as indicating what objects should be collected. 

 We commend this most useful task to the attention of the 

 Museums' Association. 



It is possible that we have a link of evidence as to the 

 relationship between the nuthatch and the woodpeckers in 

 the habit of the young of both to hiss. Those who have 

 heard a nest of young woodpeckers, deeply ensconced and
