Egyptian monuments we find there pourtrayed men of dif- 
ferent races, or, if the term is preferred, varieties, possessing 
the very same distinctive characteristics which we observe 
in their descendants in our own times. The negro of to-day 
is the exaCt counterpart of the negro figured in the most 
ancient of these sculptured records. 
If, then, permanence of type for the term of let 11s say 
three thousand years proves that certain animal species are 
immutable and primordially distinct, surely the same con- 
clusion must be extended to the varieties of the human race, 
and, e.g., the Negro, the Arab, and the Jew. must be traced 
each to a distinct and independent origin. But if M. 
Flourens and Dr. Bateman consider that these well-marked 
- — and, as we have just seen, permanent — forms have been 
produced from one common stock, it is hard to see how they 
can consistently regard a similar permanence in other 
animal forms a proof of radical diversity and of unalterable 
fixity. 
V. PROGRESS IN MICROSCOPICAL SCIENCE.* 
By W. T. Suffolk, F.R.M.S. 
f HE Fellows of the Royal Microscopical Society are 
certainly possessed of a “ Journal of which any 
learned body might be proud : the first volume, 
issued at the end of 1878, merely professed to be a Journal 
of the Society,” with other microscopical information. In the 
present volume a most important addition has been made. 
No less than two hundred and forty-eight English and foreign 
scientific periodicals are regularly examined, and theircontents 
— so far as they come within the scope of the Royal Micro- 
scopical Society’s work — indexed under the author’s names. 
The value of this arrangement to students scarcely needs 
comment : the difficulty of knowing what has been written 
and where to find it is one of the rocks ahead to all those

and Proceedings, and a Record of Current Researches relating to Inverte- 
brata, Cryptogamia, Microscopy, &c. Edited, under the direction of the
