na new form of magneto-electric machine.—When the armatures 
are dv 
are capable of developing magnetism in an electro-magnet. It is easy 
to see that the magnetism thus developed may in its turn be made to 
generate a current of electricity, and that this again may induce magnet- 
ism in a second and larger electro-magnet, and so on alternately. Mr. 
H. Wilde has availed himself of this principle to construct magneto- 
electric machines of extraordinary power. As the author’s descriptions 
are not very clear, even with the aid of figures, we shall content our- 
selves with giving the general omenuet of the peticutas and the 
results obtained with a particular machine. In this machine the genera- 
tor or primary source of the electric caren was a magneto-electric ma- 
pound each and capable of lifting cllestivel a weight of, at most, 60 
Ibs. The current from this excites en weighing three 
tons, the total weight being about rts isa a half t The armatures 
are driven at a uniform velocity of 1500 fevotutinias per minute by 
creased motive powe n unlimited i pairs o ve power an 
unlimited increase of electric i could be 6 tained, as in fact the 
whole machine is to be regarded as a means for tranaforining heat into 
mechanical power, and this last into electricity. Itis to be regretted 
that the author has given no precise data fi ich the amount of 
electricity set free can be determined with precision. The quantity of 
water dec sed per minute, with the expenditur am 
rect estimate of the value of the apparatus, as compared with that of 
other electro-motors. In any case, however, it is safe to predict a bril- 
liant and useful future for the new apparatus.—Proc. of Royal cn ome,

The vapor of hypochlorous acid is passed into chlorid of sulphur bold- 
‘ing sulphur in suspension, and the operation is discontinued as soon as 
sulphur has entirely disappeared. The chlorid of thioxyl may then ve 
separated from the chlorid of sulphur by distillation. Chior thioxyl
