exhibiting, and in manufacturing or repairing, would 

 ensue on the decease of the Marquis s right hand man 

 &quot;both for trust and skill.&quot; 



In 1670-71, letters patent were granted to the late 

 Marquis s son, Henry, Marquis of &quot;Worcester, remitting 

 payment of certain sums due to the Crown at the time 

 of his father s decease.* 



And on the 1st of August, 1672, letters patent were 

 obtained, in respect to property at Vauxhall, which state 

 that the same are granted by Charles the Second &quot; from 

 grace and favour towards Jasper Calthoff and Martha 

 Calthoff, lately deceased.&quot; From the same document we 

 learn in reference to their children, that there were then 

 living, Catherine, married to Claude Denis, 

 Jasper Calthoff, and 

 Isabel Calthoff. 



And we find from letters patent, bearing date 22nd 

 March, 1667-8, that Peter Jacobson (married to another 

 daughter) is named as the &quot;son in law,&quot; So that it would 

 appear that, in 1672, four children were living, one son 

 and three daughters. The Peter Jacobson, here named, 

 was a sugar baker, holding a portion of the Vauxhall 

 estate for carrying on his business, at a trifling rental, 

 during the term of his natural life.f 



Beyond all question the Marquis of Worcester s 

 prime invention, the Water-commanding Engine, was 

 erected and at work from 1663, to the year 1670, 

 during which time it had been made the subject of an 

 Act of Parliament ; had been published in the Century, 

 in brief outline; also noticed in a separate pam 

 phlet, copies of which are exceedingly rare ; and
