" These are to ccrtily that Dvs. Marshall .and Walker 

 have administered the vaccine uiociilation to such of the 

 crews ot' all his nia^jefJty's ships under mv cominand at 

 Gibraltar, Minorca, Malta, the Port of Marniorice, and 

 on tlie coast of Egypt, as had the opportunity and were de- 

 sirous of .submitting to the o[)eration : that tnese e;enilemen 

 have manifested the greatest assiduity for the extension of 

 the practice, bestowed the most unwearied attention to its 

 successful application, and have, according to the informa- 

 tion I have received from all quarters, exhibited it with 

 perfect success.

 tended at the hospital at Malta for the purpose of inocu- 

 lating the respective regiments of the expedition to Euvpt, 

 according to the general orders of the late commandeer in 

 chief Sir Ralpli Abercrombie. at which time the small-pox 

 had got into the fleet, and was very fatal. 



" Dr. Walker accompanied the expedition, with the ap- 

 probation of the connnander in chief, to Egypt, and intro- 

 duced the new practice into the army in general, which was 

 found cHectual in arresting the ravages of the small-pox ; 

 those soldiers escaping it who submitted to this operation' 

 and doing their duty as usual, while a few who ncirlectcd 

 the opportunity were laid up. ^ 



" W^e now experience his services in another way, he 

 having consented to be associated with the surgeon of the 

 brigade of seamen onshore; and from Sir Sydney Smith 

 finding it necessary to have the attendance of 'the surgeon 

 at a distance from the camp, the medical care of the w^iole 

 brigade falls upon him. 



'* '^'«i"i'-general Hutchinson feels a sincere pleasure in 

 rccoiniiiending Drs. Marshall and Walker (for their inde- 

 fatigable zeal in the service) to his royal highness the duke 

 of York, w ho ever takes so lively an interest in whatever 

 renders the situation of the soldier comfortable.
