fcventy bad grains occupied precifely as much ground as

Result. 



No. l/?. That divifion on which a hundred good grains 

 were fown, produced ninety-five plants. 



id. That on which a hundred lean grains were (own 

 yielded ninety-fix. 



yl> That divifion on which was fown the one hundred 

 and fcventy hungry grains, yielded alfo ninety-fix. 



On the firft appearance of the feed leaves above ground, 

 thofe of No. i ft were broader, and more fucculent than 

 thofe of the other two plots ; but as the plants advanced 

 towards perfection, the difference in appearance gradually 

 began to difappear, and long before harveft it-was not pof- 

 fible to remark any difference in the healthinefs and luxu- 

 riancy of the ftalks in any of the three divifions. The 

 grain when ripe was equally healthy in No. 3d as in fro. 1 ft, 

 and the crop feemingly as weighty in every refpeel : but 

 this I could not afcertain with the certainty I wifhed, on 

 account of the deftrucYion by birds. 



The refult of this experiment was, in truth, very con- 

 trary to what I had expected. If No. 2d only had been 

 fown with the lean grain, I fhould have attributed the 

 health and vigour of the plants to its thinnefs: but, with- 

 out the aid of that circumftance, the plants in No. 3d were 

 equally ftrong and vigorous. I mean not, however, at 

 prefent, to make any farther ufe of this experiment than 

 barely to remark how very dangerous it is in farming, to 

 rely implicitly on reafoning from analogy between two 

 cafes that are not in every refpefi alike, though they may re- 

 femble each other in many ftrilcing particulars. It would
