From 55NATURE says : -" As a means of quickly training A manunt prints from photographic Nigarries it should be extremely 14seful."

Dr. HAMPSON'S AIR-LIQUEFIER is now made to a standard pat. tern, and numbers are in use in University Laboratories and elsewhere in various countries. The whole apparatus is neat and compact and its parts very easily moved ; the Liquefier, without stand, being a cylinder 17 inches high and 8 inches in diameter.

It begins to liquefy air in from 6 to 10 minutes after the admission of air at from 150 to 200 atmospberes pressure, making over a litre of liquid per hour.

It requires no auxiliary refrigerant and produces a perfectly clear liquid which requires no filtering.

The operator has only one gauge to watch and one valve to control.

Direct Reading. No Levers. Open Scale. Very Sensitive.

[graphic]

Quite unlike all other apparatus devised for the same purpose, this instru: ment has no multiplying levers in its construction, and thus obviates all possibilities of error through any slight fault in the curvature of the bar being greatly magnified in direct ratio to the magnifying power of the levers. It depends for its action on the use of widely differing coefficients of expansion, namely, Nickel Steel and Vulcanite, which give sufficient direct move. ment, without the use of levers or other gear. This action produces a range of about three-quarters of an inch for every 10° F.

It is supplied, complete, with clock and drum, and records continuously for a week without changing the chart. Price £2 17s. 6d., complete, with 8 day clock.
