96, pp. 735-74 1, Loewy gives an account of an instrument which he calls an "equatorial coude," designed (I) to attain greater stability and so to measure larger angles than is generally possible with the ordinary equatorial; (2) to enable a single astronomer to point the telescope and make observations in any part of the sky without changing his position; (3) to abolish the usual expensive dome, and to substitute a covered shed on wheels (which can be run back at pleasure), leaving the telescope in the open air, the observer alone being sheltered.
The instrument in some respects resembles the equatorial equatorial coude of Loewy, but instead of two mirrors Camp there is only one.
The most extended and elaborate work of this sort yet undertaken is that of Maurice Loewy (1833-1907) and Pierre Puiseux at the Paris observatory, of which the first part was published in 1895.
