An important and timely paper on an interesting .subject, the data Wliicli the author wa-s 

 ahle to compile showing that since Auduljon's time the area inhabited by the .species has 

 greatly decreased in extent, no Ics.s tlian seven States and one Territory formerly oeciipied, in

Demonstrating thiit liglit acting upon extremely thin films of silver chloride sets free chlo- 

 rine to the extent of 8.ri7 per cent, or more, and tliat a f(nantity of metallic silver equivalent

 Thi.s paper contain.s a description of the variation in the foli.ago of the only living si)ecies, 

 Liriodendron tulipifera. The different forms of leaves are figured and compared with tlie 

 ajicient types, and it has been stated that most of these ancient forms, described as species, do 

 not differ in any higher degree from each other than does a .series of leaves of the recent tree 

 when studied at ditierent stages, from the germination to the mature stage.

This article calls attention to the poor manner in which the plants are often preserved in 

 the herbaria in tliis country. Instead of fixing the specimens with glue to the p.aper it is 

 recommended merely to use gummed strips of ])aper, so that the plants may easily be taken off 

 and handled for studies of various kinds.
