20 On the Prevention and Cure of 



III. On the Prevention and Cure of certain Diseases of 



the Silk- Worm. 



Sir, 



CONSIDERING that every information,^ hich 

 has a tendency to enlarge our stock of knowledge on 

 subjects connected with manufactures, ought, at the 

 present crisis, to be generally diffused ; and observing 

 the attention of our countrymen called in the public 

 prints to the culture of silk ; I have translated the fol- 

 lowing extract from an Italian Memoir, on the use of 

 the oxygenated muriatic acid gas, for the purification of 

 rooms set apart for Si Ik- Worms. This gas has also been 

 found a useful remedy for their diseases. These re- 

 marks may therefore become useful to the American cul- 

 tivators of this branch of rural economy; I therefore 

 beg leave to communicate, them to the public through 

 your valuable periodical work. 



I have the honour, &c, 

 July 29th, 1807. E. Cutbusii.
