Botanischer Practicum. As the original, it contains thirty-two 

 chapters beginning with the use of the microscope, proceeding to 

 the examination of cells and tissues, the epidermis being treated 

 separately, passing to the study of vegetative organs, and next to 

 the various groups, beginning with protophyta and ending with 

 angiosperms. The volume is well illustrated and handsomely 

 printed. The appendix treats of various re-agents recommended 

 for use. 



Marah over Megarrhiza^ Torr. — Priority of Dr. Kellogg' s Genus. 



Mary K. Curran.. (Bull. Cal Acad. Sci., ii., pp. 521-524.) 

 It appears that the generic name Marah, Kellogg, was pub- 

 lished in the Proceedings of the California Academy, Vol. i., p. 

 38, in 1855, while Dr. Torrey's Megarrhiza came in the follow- 

 ing year. If the reference of these plants to Echinocystis by 

 Bentham and Hooker and Professor Greene is to obtain, the rel- 

 ative age of the other two generic names has no special impor-

Mimicry among Plants, 



Sci. Phila., 1888, pp. 12, 13.) 



Professor Rothrock groups the cases of mimicry under two

 family, and gives interesting examples of both.

 Pathology of Pollen in jEstivis or Hay-fever. Samuel Lock- 

 wood, (Journ, N. Y. Micros. Soc, iv., pp. 99-105, one 

 plate.) 



Prof Lockwood, presents an illustrated paper on the relations 

 of pollen in hay-fever. His most pertinent suggestion is as to its 

 action as a *' pseudo-parasite." Referring to the well-known 

 disposition of pollen to send its tubes down into moist surfaces, 

 he thinks that this action may be induced when it comes into 

 contact with the mucous membrane of the nose, thus causing the 

 acute stinging pain which is such a persistent symptom of the
