94 BOTANICAL GAZETTE. [ April, 
September 5, 1816, and began the practice of medicine in Paris in 1843. Soon 
after the withdrawal of Louis from active life the two brothers removed to 
Hyeres on the Mediterranean, where they passed the remainder of their lives in 
seclusion, absorbed in the service of the Roman Catholic Church of which they 
had always been most devout followers. 
From a letter written by Dr. Vidal to the President of the Academy at 
Paris, we learn that, on December 22, M. L. R. Tulasne, who appeared to be in 
good health, accompanied a friend for a part of the way from his own residence 
to Hyeres, but on his return he was suddenly seized with an apoplectic fit and 
remained unconscious until his death at4.p.m. The following extract from Dr. 
Vidal’s letter expresses the esteem in which M. Tulasne was held by his neigh- 
bors: “ You will have at ssid: all the ees regarding his scientific work; 
but what will never be known is the a f good which he did to those abot 
him. M. Tulasne lived very seit in the country; he received all persons 
with the same affability, but one saw that, to interest him actively, it was nec- 
essary to point out to him those who were unfortunate and in need of consola. 
tion, and then his goodness and charity were equally inexhaustible. Aided by 
his brother, Dr. Tulasne, who died last year, he established charitable institu- 
tions pretty nearly everywhere in this region. His life so well spent may be 
summed up by saying that he did good, nothing but good and always good.” 
In their botanical works the illustrations were generally made by Charles, 
while the text was written by Louis, although, in a number of cases, the text 
was the joint work of both. Of the fifty titles given under their names in the 
Royal Society’s Catalogue, eleven bear the names of both brothers. Their ac- 
tive work began with “Observations sur le genre Elaphomyces,” in the Annales 
des Sciences of 1841, and their latest work was probably the paper on Tremellini 
in the Annales of 1872. Of their contributions to phenogamic botany the most 
important were monographs of the Podostemacece and Monimiacee in the Arch- 
ives du Museum, some articles on Leguminose, and an account of Madagascar 
plants, all showing careful and accurate work in descriptive botany, while the 
“ Etude d’embryologie Mrs ” in the Annales of 1847, showed their ability 
in a very different and difficu Id. 
ut it is in connection Hii their work on the structure and development 
of fungi that they are best known and, in this department of botany, their 
writings, we might almost say, form the basis of modern views on the subject. 
As in most all cases Charles furnished the illustrations and, at times, also a por- 
tion of the text, we need not distinguish between the two brothers in speaking 
of their mycological works. Their attention was, at first, directed to hy 
fungi, and from them it naturally turned to the structure of Gasteromycetes, an 
order which was in a chaotic condition at that time. The structure and affini- 
ties of the principal genera of this order formed the subject of several of their 
pape. The Ustilaginee and Uredinee were tr2ated in two important papers, 
“ = 
1847, and “Second Mémoire sur les Urédinées et les Ustilaginées, ” in 1854. In 
these two admirable papers, to a knowledge of the anatomy there was added a 
study of the germination and development of the spores in the different genera
