In concluding these remarks, it may be proper to 

 observe, that, as some of the above operations re- 

 quire a considerable degree of manual dexterity, it 

 will be necessary for the right execution of them, 

 that a person be employed for that purpose, who has 

 previously been accustomed to work in the nursery.
