In the Monday edition of the newspaper Sud-Ouest, Michèle Delaunay, a junior minister and former dermatologist, revealed assets valued at 5.4 million euros (about $7 million), a number she said she feared would be “difficult to understand for the majority of the French.”

Laurent Fabius, who in addition to serving as foreign minister is the grandson of an important early-20th-century art dealer, kept mum about his holdings until Monday evening, when he revealed assets totaling about 6 million euros (about $7.8 million).

Some tried to defuse tensions with self-derision.

“I have a T-shirt from David Beckham, so I think I need to put that in my estate declaration,” Aurélie Filippetti, the culture minister, told France 2 television last week, while insisting that her 71-square-meter Parisian apartment was her sole possession of consequence. (The apartment was valued at 710,000 euros — about $925,000 — in her declaration Monday. She also disclosed about 11,000 euros, or $14,400, in the bank and 314,000 euros, or about $410,000, in debt; the T-shirt was not listed.)

Jean-Luc Mélenchon, a fixture on the far left but not a member of the government, volunteered on his blog that he owned an apartment in Paris (purchased for 346,750 euros, about $453,000), a country house (purchased in 1996 for the equivalent of $120,000), and savings of 150,000 euros, or about $196,000. First, however, he noted: “I measure 1.74 meters tall. I weigh 79 kilos.”

Mr. Mélenchon went on to list his waist measurement and shoe size, and to note that his hair is “natural” and “not dyed.” He is also looking for a larger apartment, he said, and thanked “those who can make me a good offer.”

Mr. Mélenchon and other critics have noted that it seems unlikely the disclosures could have caught Mr. Cahuzac, especially because they were not accompanied by an enforcement mechanism, at least not yet.

If a disclosure is not independently verified, “it’s worth nothing,” said Jean-François Copé, the president the Union for a Popular Movement, the center-right political party that is the primary opposition to Mr. Hollande’s Socialist Party.
