Our opinion of this measure, excepting the above mentioned clauses, is 
well expressed in the words of Dr. Samuel Adams, in the Morgan Co. 
Med. Society: I am inclined to give this law my approval without 
being very hopeful of the. success of such legislation.” 
The fungus of Favus .—In our remarks on a case of favus reported in 
the January number we stated that Dr. Tilbury Fox of London believed 
the fungi of favus, herpes, etc, to be difiererit stages and modifications of 
development of Aspergillus, whereas an experiment of cultivation of our' 
own yielded an abundant crop of Penicillium ,—a result confirmed by some 
other authors. We are happy to find that the apparent difference is 
readily reconciled. In a letter dated May 5, 1868, Dr. Fox writes to us: 
“I have read with much interest your case of favus; but wish to point 
out that I use the words Penicillium. and Aspergillus as synonymous, 
because they only differ in the fact of one having a receptacle or placenta 
(Aspergillus), and the other being without it. In fact, in my germina¬ 
tions I have seen the two forms on one and the same mycelial base.” * » 
We may have occasion to refer to this letter again. At this time we wish 
merely to make this correction, and to acknowledge the receipt of two 
valuable pamphlets by the same affthor, with our best thanks; G. B,
