packed for transportation, the transverse bar which joins the 
body to the rack has in nearly every case given way under some 
unfortunate jar and become hopelessly though not conspicuously 
deformed. The untimely removal of -the set of comparatively 
unfamiliar objectives from the exhibition could not have been an 
intentional breach of courtesy or propriety, but was certainly an 
unfortunate mistake on the part of both the proprietors who 
desired and the officials who permitted it. | 
l R. and J. Beck’s exhibit is perhaps the most complete in the 
exhibition, but is so badly displayed as to present a scarcely 
| attractive appearance. The large number of standard forms 
_ and the numerous and convenient accessories made by this firm 
| have been so extensively exhibited and sold in this country that 
their peculiarities are well known. The chief novelties are a 
much-needed addition of centring and rotating adjustments to 
the substage, and a showy introduction of aluminium mountings 
in some of the stands. 
Henry Crouch, of London, also exhibits a full series of instru- 
ments characterized by a greatly improved quality of moderate- 
priced work, a class of work for which there is an increasing ap- 
Preciation and a growing demand. His best stands of medium 
size lack scarcely any advantage as compared with far more 
clumsy and costly first-class stands. His variety of accessories 18 
large and well selected, showing an earnest endeavor to adopt 
the best novelties from every source. His manufacture of a small 
histological instrument, with short body, low stage, and horse- 
shoe base, after the Continental method, is one more evidence of
