Later, Dr. Andrew Clarke, of London, adoptedsmaller bulbs, so that they can be compressed by thehand. It seems to me that the main advantage of thedouble bulb is, that pumping is thus rendered less labor-ious, for I do not conceive that there is anything to begained for purposes of inhalation by the production of acontinuous stream; at times, indeed, rather the reverse,for the expiratory current regularly interrupts the inha-lation necessarily, and may thus cause a waste of fluid. CODMAN & BQSTDN. (Modification of) Clarkes Nebulizer. A, nebulizing tubes; B, mouth speculum ; C, bottle for medicated solution; D,rubber band-eompressor; F, joint permitting the mouth speculum to be removed,or turned aside. A convenient arrangement for hand-use is shown inFig. 200 NEBULIZED MEDICAMENTS Dr. G. J. Arnold, of Roxbury, describes* an appa-ratus in which he employs hydrostatic pressure as thepropelling force. The horizontal tube of a Bergsonapparatus is connected with the upper portion of an airreservoir by means of a stopcock and rubber tubing;another reservoir filled with water is placed at a higherelevation ; as the water from the latter flows into the lowerportion of the air reservoir, the air within it is com-pressed, and when sufficient pressure has been obtained,the stopcock is opened, and the compressed air escapingthrough the horizontal tube produces the nebulization. It is not often that it is requisite to administer inha-lations in ones office; but where this is done a greatdeal, it has been found advantageous by some practition-ers to employ a pneumatic re
