that of Miller on the constitution of ephe- 

 drine; the researches of Paul and Cownley on 

 the alkaloids of ipecac; and those of Fischer, 

 Schlotterbeek and others on various alkaloids, 

 which have been published in the past few 

 years in the Proceedings of the American 

 Pharmaceutical Association. The physiolog- 

 ical properties given in connection with some 

 of the alkaloids might well be omitted in a 

 work of this kind, particularly as a few of 

 them are not entirely accurate. The index 

 would be more helpful if the plant names 

 were included in all cases, in addition to the 

 names of the alkaloids derived from them. 

 An enlargement on the parts dealing with 

 physical properties and important chemical 

 tests would add to the value of the book and 

 make it appreciated by a larger number.

SOCIETIES AND ACADEMIES. 



THE TOEEEY BOTANICAL CLUB. 



The club met in the morphological labora- 

 tory at the New York Botanical Garden, 

 March 30, 1904. 



The first paper on the scientific program 

 was ' Notes on the Cytology of the Aquatic 

 Fungi,' by Dr. Cyrus A. King. Schroeter's 

 classification of the Phycomycetes was re- 

 viewed and attention called to the fact that 

 the conidia of the Peronosporineas resemble 

 sporangia since they germinate by forming 

 internal zoospores. In the Saprolegniaceas, 

 according to Trow, the eggs are at first mul- 

 tinucleate, all except the sexual nucleus in 

 each egg being disposed of by digestion. Dr. 

 King'^ researches have shown that in the Lep- 

 tomitacese, as far as known, the oogonia are at 

 iu'st multinucleate and the supernumerary 

 nuclei are disposed of by migrating to the 

 periphery of the cell where they are cut off 

 in a distinct periplasm. In Araiospora the 

 peripheral nuclei surround themselves with 

 cell walls in such a way that the ooplasm is 

 surrounded by a layer of periplasmic cells. 

 In Sapromyces there is also a periplasm in 

 which the nonsexual nuclei are cut off; it is, 

 however, reduced to a very thin layer. The 

 formation of a body in the center of the egg
