"Notice" is a very odd word to use for "exhibition" though. I am pretty sure this is what it means in this specific instance.

Notice des tableaux de la Galerie Espagnole exposés dans les salles du Musée Royal au Louvre, Galerie Louise Philippe, Paris, 1838
=
Exhibition of the paintings from the Galerie Espagnole exhibited in the rooms of the Musée Royal au Louvre, Galerie Louise Philippe, Paris, 1838

Very likely this is a small printed document given to exhibition visitors.

Something akin to a modern "exhibition checklist", except that it has descriptions rather than reproductions.

Don't know why it's in the exhibition section though, unless an exhibition was based on that particular catalogue, which seems unlikely.

examples:

The Descriptive Catalogue of Paintings in the Gallery of Daniel Pratt, published in 1853, describes, in addition to the interior of St. Peter's paintings of historical subjects like the Landing of Cleopatra and Landing of Columbus, romantic landscapes including the Falls of Niagara, the Natural Bridge, Virginia, and Naples, and portraits of such prominent figures as George Washington and Henry Clay.

W. H. J. Weale and Jean Paul Richter. A Descriptive Catalogue of the Collection of Pictures Belonging to the Earl of Northbrook. London, 1889, pp. 182–83, no. 237, cites it in the collection of the Earl of Northbrook; transcribes the date as 1643.

That particular exhibition was special:

"Unquestionably, the key event in the surge of Hispanism in France was the 1838 opening of King Louis-Philippe d’Orléans’s Galerie Espagnole in the Louvre. Orchestrated by Baron Taylor, the Spanish Gallery assembled 400 paintings, from late sixteenth-century works by El Greco and Morales to masterpieces by Zurbarán and Murillo to major canvases by Goya, to become, in effect, a competitor with the Prado itself."
