Catalogue of North American Plants. J. H. Oyster. (2d Ed., 

 Pamph., 8vo., pp. 125, Paola, Kansas, 1888). 

 This check-list is a great improvement on the original one of 

 Di". Oyster, both in completeness and in typography. Indeed 

 we note really few errors. The paper is poor, however, and the 

 font of type used was old and dull. The number of species 

 enumerated reaches 10,123, contained in 1665 genera. A good 

 feature of the list is the appended index. The alphabetical 

 arrangement adopted by Patterson is followed both as to genera 

 and species; now let Mr. Patterson adopt the plan of numbering 

 both species and varieties — with an index. 



Cinchona in Bolivia— The Cultivation of—H. H. Rusby, M.D. 

 (Reprinted from the Pharmaceutical Record, Oct. I, 1887). 

 This is one of the most important botanical papers read at 

 the New York meeting of the American Association, when it was 

 elaborately illustrated by a fine series of the bark and mounted 

 specimens of the various species and hybrids collected by Dr. 

 Rusby during his visit to the Cinchona plantations. After 

 niaking an interesting comparison between the pure stock Cin- 

 chonas cultivated in India and the mixed hybrids cultivated in 

 South America, the author proceeds to state some of the fallacies 

 in characterizing species and concludes the essay with brief des- 

 criptions of the fifteen species, varieties and hybrids, in cultivation 

 in the Mapiri District.
