In his rapid response: "HIV EM and purification", 28 June, Nicholas Bennett wrote:  "Asking for an EM from a virus that hasn't been culturedů.is simply setting up a straw-man argument".


A few days later in his rapid response: "Re: HIV EM and purification", 1 July, Nicholas Bennett wrote:  "However, it should be born in mind that a viral load of 1 million per ml still equates to a relative volume of 9*10^-16.  In other words, a million virus particles make up less than one thousandth of a trillionth of the total volume of the blood.  Trying to find a virus particle in that situation would be a complete waste of effort.  That however hardly detracts from any argument of causality.  It is perhaps sad that a respected EM researcher such as de-Harven didn't appreciate this simple fact of impossibility".


When, in our rapid response: "One AIDS patient will suffice", 6 July, we drew Christopher Noble's attention to the fact that according to electron microscopists, including Hans Gelderblom, it is possible to visualise 106 virus particles per ml in plasma, he personally contacted Hans Gelderblom.  Hans Gelderblom confirmed that 106 virus particles per ml of plasma can be visualised.  He also stated that although he repeatedly tried to detect "HIV" particles in the plasma he failed and gave up searching for them ten years ago.


This led Nicholas Bennett to state in his rapid response: "Re: Where is the virus?", 10 July: "I'm amazed at the Perth Group's consistency in jumping to conclusions "they are not there to be found" instead of entertaining the even slightly plausible option of "maybe it's difficult to find them in this way, and we need to use another method".


Would Nicholas Bennett please give us a method other than EM with which "HIV" particles can be visualised in plasma.  Has this method been used and what are the results?
