✦ Synopsis

builder, he must go to the expense of having them made, which will, in most cases, he too great an expense. Itis highly improbable that these dies be found anywhere except, perhaps, in I.ondon, where they were doubtless made for this special purpose. He states that these links may be bought for $~ per gross, hut, unfortunately the reader is left to 13nd out where to buy them.

in some cases, the language is not clear and will doubtless give the builder some trouble. For instance, in his own calculations, the same frame when series-wound will have double the amp&e turns in the field that are required when shunt-wound. There is evidently something wrong somewhere and the reader, if of an inquiring mind, as is generally the case, will' be greatly puzzled. Such over-saturation surely cannot have been intended.
