The Architecture of the Human Body. — Professor 
Humphrey, in his fourth lecture on this subject at the Royal 
Institution, said that as the tail diminishes in animals the 
hinder limbs seem to grow out. Thus, the serpent is nearly 
all tail and no limbs : the whale, with its shortened trunk, 
has a broad flat tail ; also, as the tail of the tadpole disappears, 
the hind legs, of the frog take its place. Man has the bones 
of a small incipient tail, with three flat sides ; this tail turns 
inwards, so that the human being is really the only animal in 
creation who can occupy an arm-chair in comfort. The head 
of the thigh-joint rests in a socket so very shallow that it 
is only held in its place by atmospheric pressure and the 
ligaments surrounding the joint; and the leg swings to and 
fro below this shallow socket very much like a pendulum. —

There is a project on foot in Paris for the formation of a 
museum containing the best examples that can be found 
of the various types of the human race, not for scientific 
purposes only, but also in the interest of art. M. Charles 
Rochet has introduced the subject in a lecture at the Sor- 
bonne. — Standard. 
Leptothrix and Vibrio Bacillus. — MM. Giuseppe 
Balsamo Crivelli and Leopold Maggi have an important 
paper in the f llendiconti del Reale Istituto Lombardo 3 (ser. 
ii, vol. i, p. 11) on the above organisms. They affirm that
