Microscopical researches into the accordance in the structure 
and growth of animals and plants. Sydenham Society, London, 
1847. 
This is the Enelish translation by Henry Smith of Schwann’s 
oD y ie 
epoch-making paper, Mikroskopische Untersuchungen, ete., pub- 
lished in 1839. One of the great classics in biology, 
of the present treatise is to prove the most intimate connection of 
“The object 
the two kingdoms of organic nature, from the similarity in the 
laws of development of the elementary parts of animals and plants 
... Schleiden communicated the results of his investigations to 
me previous to their publication in October, 1837,” says Schwann. 
“ The development of the proposition, that there exists one general 
principle for the formation of a 
— 
| organic productions, and that 
this principle is the formation of cells, as well as the conclusions 
that may be drawn from this proposition, may be comprised under 
the term cell-theory”’ (Schwann).

Senebier made fundamental contributions to our understanding 
of the functions of respiration and photosynthesis. ‘‘ Leaves re- 
store to the air a part of the oxygen gas which animal life and 
various other circumstances take from it, as Priestley, Ingenhous, 
and I have shown.”
