gardens at the roots of divers plants, but never succeeded 

 in bringing it to perfection. The author above mentioned 

 describes four other species of root-worms ; viz. musca se-

I flatter myself, that this valuable Essay of Mr. Walford's 

 will stimulate other gentlemen who reside in the country, 

 and who arc so materially interested, to enter seriously into 

 a minute examination of the various causes,, by which grain 

 is so frequently destroyed ; so that, by a number of such 

 inquiries and communications, we may at length be ena- 

 bled to point out a remedy — as every grain of corn that can 

 be preserved in times like the present must be a public be- 

 nefit. 



Mr. Bierkander's papers on the different root-worms I 

 got translated by a friend ; and the translation, with some 

 remarks of my own, was some time since presented to the 

 J3oard of Agriculture.

An Account of the larger and lesser Species of Horse-shoe

England. This was originally discovered by Doctor La- 

 tham, who communicated it to Mr. Pennant, and he first 

 made it public in his British Zoology, where he states jt to 

 be found in the salt-petre houses belonging to the powder 

 mills at Dartford, frequenting those places in the evening 

 for the sake of gnats ; and also observed during winter in a
