the apparatus necessary for a standard set of physio- 

 logical experiments for an elementary course in Botany 

 will be offered for sale at a fair cost, precisely as such 

 apparatus is now offered for the Harvard Entrance 

 Requirement in Physics. 



Abundant materials in proper condition are a ne-

 botanical supply company. If the teacher has at 

 command his own greenhouse and gardener, as many

 tanic garden, he will find the director ready to aid 

 him in anything which advances botanical knowledge. 

 Commercial greenhouses, happily, are everywhere,
