corn, two of rice, two of common garden beans, two of Kafir corn, 

 two of barley, two of wheat, one of oats, etc. In all the experiments 

 only sound seeds were taken, being, so far as possible, from a single 

 stock in each case. Two lots of treated seeds each containing 200 

 seeds of the larger species and 1 00 of the smaller kinds were used. 

 Similar lots of untreated seeds were employed as checks. 



EXPERIMENTS IN A SATURATED ATMOSPHERE OF CARBON BISULPHID. 



In the first series of experiments the seeds were placed in shallow 

 glass vessels, resting on a plate of ground glass covered with a bell 

 jar containing a saturated atmosphere of carbon bisulphid. At the 

 end of 48 hours the seeds were transferred to the germinating cham- 

 ber, in which were placed also the check lots of untreated seed. 



The following table gives in detail the result of the experiment, 

 the figures representing the averages of the germination of the two 

 lots of each kind, both of treated and untreated seed.
