172:“Le développement des conferves est aussi simple que leur structure; il s'opère par l'addition de nouvelles cellules aux anciennes, et cette addition se fait toujours par l'extrémité. The terminal cellule becomes more dense than the infield cellule; then a medium production takes place in the internal fluid, which tends to divide the cellule into two parts of which the infield remains stationary, while the terminal cell becomes denser again, producing yet another new internal cell, and so on. Is the production of the middle coat originally double or simple? Voilà ce qu'il est impossible de déterminer; mais toujours est-il vrai de dire que plus tard elle paraît double dans les conjuguées, et que quand deux cellules se séparent naturellement, chacune d'elles est close aux deux extrémités.”
178:“The development of the conferve is as simple as its structure; it takes place by the attachment of new cells to the old, and this attachment always takes place from the end. The terminal cell elongates more than the deeper cells; then the production of a lateral bisector takes place in the inner fluid, which tends to divide the cell into two parts, of which the deeper one remains stationary, while the terminal part elongates again, forms a new inner partition, and so on. Is the production of the middle partition originally double or single? It is impossible to determine this, but it is always true that it later appears double when united, and that when two cells naturally separate, each of them is closed at both ends.”

When the company that ran the
Brussels’ botanic garden collapsed, Dumortier developed the idea of a state-owned botanic garden in the capital. He succeeded in convincing the Parliament in 1869 of buying the impressive herbarium and dried collections of the late Carl Friedrich Philipp von Martius. A

In 1831 he became a member of the first elected parliament of the new kingdom, as the member for
Tournai. He remained elected until 1847. He then switched seats and was now elected for the city of Roulers and held this seat until his death.

In 1872 he was awarded the honorary title of
Minister of State. He also was awarded nobility with the title of earl. However, for unknown reasons, he did not raise the necessary patent letters and was therefore not ennobled.

Barthélemy
Dumortier was a son of the merchant and city councillor Barthélemy-François Dumortier and of Mariue-Jeanne Willaumez. He married Philippine Ruteau and they had a son, Barthélemy-Noël Dumortier (1830-1915).

few months later the state bought the garden of the 'Société Royale d’Horticulture de
Belgique'. Dumortier hoped to create a botanic garden whose role model was the Royal Kew Gardens.
