The next day Lakanal, after a short conference with his colleagues of the Committee of Public Instruction, read in the tribune a short report and a decree which the Committee adopted without discussion.
Their minds were elsewhere, for grave news had come in from all quarters.

The Austrians were bombarding Valenciennes, the Prussians had invested Mayence, the Spanish were menacing Perpignan, and bands of Vendeans had seized Saumur after a bloody battle; while at Caen, at Evreux, at Bordeaux, at Marseilles, and elsewhere, muttered the thunders of the outbreaks provoked by the proscription of the Girondins.

So that under these alarming conditions the decree of the 10th of June, in spite of its importance to science and higher learning in France, was passed without discussion.
In his _Lamarck_ De Mortillet states explicitly that Lamarck, in his address of 1790, changed the name of the Jardin du Roi to Jardin des Plantes.[30] As the article states, "Entirely devoted to his studies, Lamarck entered into no intrigue under the falling monarchy, so he always remained in a position straitened and inferior to his merits." It was owing to this and his retired mode of life that the single-minded student of nature was not disturbed in his studies and meditations by the Revolution.

And when the name of the Jardin du Roi threatened to be fatal to this establishment, it was he who presented a memoir to transform it, under the name of Jardin des Plantes, into an institution of higher instruction, with six professors.

In 1793, Lakanal adopted Lamarck's plan, and, enlarging upon it, created twelve chairs for the teaching of the natural sciences.
Bourguin thus puts the matter: "In June, 1793, Lakanal, having learned that 'the Vandals' (that is his expression) had demanded of the tribune of the Convention the suppression of the Royal Garden, as being an annex of the king's palace, recurred to the memoirs of Lamarck presented in 1790 and gave his plan of organization.
