£onclufion. On the facls expofed I could greatly enlarge, but I think 



on all accounts it is bed at prefent to offer them in their 

 prefent form to the reafoning faculties of your readers. At 

 any rate they may ferve as data, and if they thou id fail to 

 bring others to my opipion, may aft, I truft, as ufeful ftimu- 

 lants to the further inveftigation of a very curious fubjecVof 

 enquiry, as to what are the nature of the enemies tp the per-. 

 feclipn 0/ pur wheat harvefl. 



With refpeft and efteem,

T£c vicinity of ?• &' J* ou gM to obferve, that on the grains of wheat fown 



th&barberry does near the barberry, I I ad no opportunity of making obferva-* 



stffedTgr in tions ; but that I have a dried root of wheat now by me, on 



which there are above 100 draws that are all clean and found, 



though it grew a few years ago in a garden where barberry 



bufhes were.

Experimental Invejiigations concerning Heat. J?yBENJAMiT? 

 Count of Rumford, V.P.R.S. 9c c, 



(Concluded from Page 75.) 



Sect. IIL Experiments tending tojhexv that Heat is communis 

 cated through Jblid Hodies, by a Law ivhich is the fame as that 

 uhkk would enfue from Radiation bttxeen the Particles. 



Objeil of in- AJlAVING made a confiderable number of experiments on. 

 quiry j the laws the paffage of heat through fluids, and through different fub- 

 tion o/heatln ^ ances m lne ^ ate °f powder, I was curious to afcertain the 

 folids. Jaws of its propagation through folic! bodies, particularly me* 



tals. 



I hoped this difcovery would furnifli fome additional data, 



to confirm or refute the opinions I had adopted concerning hea^ 



and its manner of acling ; and it will be feen by the refults, 



that my expectations were not fruftrated.
