I remain. 

 Sir, 

 Your humble Servant, 



ARNOLD MERRICK; 



Querri's Hoad, Cirencester, 

 22d Sep(. 1812. 



ir. 



On the secret and open Nectaries of various Flowers. In a Let- 

 ter from Mrs. Agnes Ibbetson. 



To Mr. Nicholson. 

 SIR, 



IN the exact dissection I have given of a flower in your 

 Journal for July last, the explanations of the calyx, corolla, 

 aud stamen, were alternately given, their peculiar vessels de- 

 scribed, and the separate cylinders, which convey those vessels 

 to the stalk, accurately and exactly marked. There remains, 

 therefore, of the flower but two pans to develope, the nectary and 

 the pistil : the most important, indeed j and which have never, 

 I think, been rightly explained, or properly delineated, particu- 

 larly 



On the nectary 

 of flowers.
