Explanation of Chronological Listing 
Events are listed only if they are pertinent to the text of this report. 
Meetings of the Heart Council, its connnittees and the Primate Research Study 
Section group (formerly committee) are not listed unless something transpired 
that was significant to the Regional Primate Research Centers Program. The 
letters "FY" preceding a year indicate that the fiscal year is meant. One 
should bear in mind that the Federal fiscal year begins on July 1 and runs 
through the next June 30. Thus one fiscal year stands astride two calendar 
years. Furthermore, the item listed relative to a fiscal year will have been 
discussed at the Congressional Hearings about six to nine months prior to the 
beginning of the fiscal year indicated. For example, in calendar year 1958, 
the Senate appropriations subcommittee was informed by a witness that the Heart 
Institute was planning the formation of a primate colony. ^ However, since the 
testimony was in the hearings for the Fiscal Year 1959 budget, it is shown in 
this listing for "FY 1959." A fiscal year can be approximately translated into 
a calendar year by subtracting a number of months from the July 1 beginning of 
a fiscal year: subtact nine months in case of House Hearings and six months 
in case of Senate Hearings.
